Pole Position

FLEW to Poland today for the Adolf Anderssen Memorial, which is being held in his birth-place of Wrocław (more commonly known as Breslau in the 19th century).
Ryanair flies direct to the Silesian city, which is always something of a good-news/bad-news situation.
The bad news today was that Ryanair told me to be at Stansted airport three-and-a-half hours before my flight was due to take off at 11:40, but checkin opened at gone 08:40.
The airline also gave me wrong information about which printed documents I needed, but otherwise checkin was fairly smooth, and passing through security even smoother.
The chess festival consists of a rapid (10 minutes with a five-second increment) today, which does not interest me, a blitz later in the week, and four "Open" tournaments - actually an over-2000, an under-2001, an under-1601 and a beginners', for children aged under 12.
I am seeded eighth of 68 in the under-2001, officially called Wrocław B, which, according to the tournament website, has an average rating of 1571, an average age of 27, nine females, 63 rated players and five federations. A slight oddity is that two of the unrated players have estimated ratings of 2000 which, if even approximately correct, would push my real ranking down to 10th.
Two players, including myself, were born in 1957 - everyone else in 1959 or later. Since I was born in February, I am probably the oldest player in the tournament.
Thirty-two players were born in 2000 or later, including two in 2010, so there is a good chance I may extend the junior fest I 'enjoyed' earlier this month in Basel.
The over-2000 and under 2001 have two rounds tomorrow, followed by one round a day for seven days. The time limit is 40 moves in 90 minutes, a 15-minute 'windback' and a 30-second increment from move one.
*************
Polish customs took about 45 minutes to get through, but standing in the queue made it seem longer - perhaps I have been spoilt by recent smooth border-crossings.

Middlegame Lessons From Basel III


White has just played 14.Bf4-d2 in Jeremias Stark (1599) - Spanton (1814), Basel Round 3
*****
*****
*****
*****
*****
Black has to move the queen, but to where? The candidate moves, in my opinion, are 14...Qh5, 14...Qe5, 14...Qc7 and 14...Qa6, and here I want to deal with them in turn.
A) 14...Qh5
This comes to be, at least for a while, the second choice of the analysis engines Stockfish14 and Komodo12.1.1. The queen is actively placed on h5. But the activity of the black pieces, including a rook that will soon come to the half-open b file, is easier to direct against the white queenside, so it makes sense to place the black queen where it can add to this pressure.
B) 14...Qe5
A queen in the middle of the board in the middlegame is powerful if it cannot be molested, but is often subject to harassment. The latter looks more likely here, but it is not clear such harassment is beneficial to White. For example, 15.f4?? is a gross blunder thanks to 15...Qd4+, while 15.Bc3 Qf4 (or 15...Qh5) 16.Bxg7 Kxg7 leaves Black without his fianchettoed bishop but with the better remaining-bishop and with exploitable dark-square weaknesses in the white position. The engines reckon the best answer to 14...Qe5 is 15.Kh1, with what they rate as approximate equality.
C) 14...Qc7
This is what I played. The queen remains on the queenside but is not very active. The engines reckon Black has, at best, a slight edge.
D) 14...Qa6
General principles in chess are often a useful guide to finding good moves, but many times two general principles clash. Here 14...Qa6 runs contrary to the general principle of not placing the queen in the firing line of a weaker piece, but conforms with the general principle of pinning enemy men (in this case the c4 pawn). I rejected 14...Qa6 because of 15.Qc2?!, missing that 15...Nb6 costs White a pawn, eg 16.Nxb6 Qxb6+ and 17...Qxb2. Note that in this line 16.c5? loses to 16...Qxa4 17.cxb6 Qxc2 18.Bxc2 Bxb2 19.Rab1 Bd4+. The engines reckon the best answer to 14...Qa6 is 15.b3!?, when Black can probably accept the exchange, but is also much better, according to the engines, after the simple 15...Nb6.
In conclusion, it seems 14...Qa6 is best.

Middlegame Lessons From Basel II


White is two pawns down in Spanton (1814) - Anuar Tureshbayev (-), Basel Round 2, but can conjure up a strong attack by finding the right move
*****
*****
*****
*****
*****
24.Rd6?
Black gets a large advantage after this with the game continuation 24...Bf5.
White needed to find 24.Bd3!, according to the analysis engines Stockfish14 and Komodo12.1.1. The first point is 24...exd4? allows a draw by 25.Bh7+ Kh8 26.Bg6+ Kg8 27.Bh7+ etc. Also drawing is 24...g6? 25.Qh6 exd4 (only move) 26.Bxg6 fxg6 27.Qxg6+ etc. That leaves 24...Rfe8, when 25.Bc4! Be6 26.Bxe6 fxe6 27.R4d3 is only slightly better for Black, according to the engines.
**********************************************************
White is still two pawns down, but can equalise by finding the right move

The game saw the hopeless retreat 28.Nf3?, but the engines point out 28.Bxf7+! Bxf7 28.Qh8+ Kxh8 29.Nxf7+ and 30.Nxd8.

Middlegame Lessons From Basel


White has just played 15.Bg6-e4 in Cyrill Speiser (1320) - Spanton (1814), Basel Round 1
*****
*****
*****
*****
*****
White is a pawn up and winning, according to Stockfish14; has a slight edge, according to Komodo12.1.1.
The fact that two strong engines can disagree to such a large extent suggests this is not an easy middlegame to judge.
However, given enough time, Stockfish14 comes to reduce White's advantage to 'only' having the upper hand (+1.28 pawns, compared with Komodo12.1.1's +0.52 pawns).
Grandmaster Nigel Davies states that the No1 factor in chess is king safety, and here White is much better situated. White's pieces are also more active.
The number of pawn-islands is equal, but clearly Black's pawn-structure is superior, which could be a significant factor in any ending.
So what should Black play?
*****
*****
*****
*****
*****
15...Be6
This is Komodo12.1.1's choice, but Stockfish14 may well be right in preferring 15...Qg7!? After 16.Qxg7+ Kxg7 both engines reckon White has the upper hand, but Black has time to complete development and try to start manoeuvring against the white queenside pawns. Of course swopping queens reduces the chance of a tactical coup, but, for reasons explained above, the tactical situation in the diagram favours White (there was also the psychological consideration that CS is a junior, and it rarely hurts to get queens off against juniors). However, White is not forced to exchange queens - 16.Qe3 keeps an edge.
16.0-0
*****
*****
*****
*****
*****
16...Kh8?
Trying for a kingside attack, but the attempt is unrealistic. Again ...Qg7 is sensible.
17.Nh4 Kg8
Forced, thanks to the threat of Ng6+, so 16...Kh8? has wasted two tempi in what was already a bad position.
**********************************************************
Can White avoid an exchange of queens by retreating to h5?
*****
*****
*****
*****
*****
Yes, as 19...Bg4? fails to 20.Bxh7+!
However, Black can play 19...Qf7, when either queens come off or the white queen has to retreat from the vicinity of the black king.
***********************************************************
Can Black grab the undefended a2 pawn?
*****
*****
*****
*****
*****
20...Bxa2?! runs into 21.Nf5+, when 21...Kg8? 22.Rd7 is the start of a massacre, so Black has to play 21...Kh8, when 22.Nd6 is unpleasant, the engines continuing 22...Na5!? 23.Ra1 Nc4 24.fxe5 fxe5 25.Nf7+!? Kg7 26.Bxb7 - a sharp line, but all variations seem good for White.
The engines reckon the best move in the diagram is 20...Rad8, when they agree White is better but disagree as to how to proceed.

Endgame Lesson From Basel

ONLY one of my five games at Basel reached an ending, but it is quite instructive.
Position after a black capture on c4 in Jeremias Stark (1599) - Spanton (1814)
*****
*****
*****
*****
*****
Black is a pawn up and has two protected passed pawns. But this is a rook-and-pawn ending, and White has compensation in the shape of an outside passed pawn, a juicy square at e6 and targets at e7 and h6. Nevertheless the analysis engines Stockfish14 and Komodo12.1.1 reckon Black is clearly winning.
45.a3
It makes sense to get the passed pawn off the same rank as the king, and the move gives White the option of following up with Ra2 or Re6. Note that 45.Kg3?! Rc3+ 46.Kg2 Ra3 helps Black.
45...h5?!
A radical and unnecessarily complicating way of dealing with the weakness at h6. Black is still much better after the text, but simpler is 45...d5, not least because 46.Re6 d4 starts a race White cannot win.
46.gxh5 Rf4?
White gets drawing chances after this. The engines reckon 46...Rh4 leaves Black in control.
47.Kg3?
Much better is 47.h6 Rh4 48.Re6, although after 48...c4 Black has the upper hand, according to Stockfish14; just a slight edge, according to Komodo12.1.1. Note that 47...Rxf5? runs into 48.h7 Kg7 49.Rxe6+, although Black has a draw after 49...Kh8, according to the engines.
47...Rxf5?!
More clear-cut is 47...Rh4.
48.Rf2!?
Stockfish14 reckons this is best, but it seems pointless in that the pawn-ending is winning for Black despite White having passed pawns on the a and h files. Komodo12.1.1 wavers between the text and 48.h6, although the latter is easily met by 48...Rf6.
Perhaps the best practical chance is 48.a4!?, when the engines reckon only 48...d5 maintains Black's advantage.
48...e6 49.Rxf5+?
The pawn-ending is lost, so White should have tried pushing the a pawn or relocating the rook.
49...exf5 50.h4?!
This comes to be Komodo12.1.1's choice, at least for a while, but it makes Black's task easy. A better practical try is 50.a4, but 50...c4 wins after 51.a5 c3 52.a6 c2 53.a7 c1=Q 54.a8=Q Qg1+ 55.Qg2 (55.Kf3 Qh1+) Qxg2 56.Kxg2 and after 51.Kf2 c3 52.Ke2 f4 53.a5 (what else?) f3+ etc.
50...gxh4+ 51.Kxh4 c4 (1-0, 58 moves).

Opening Lessons From Basel V

IN round five I had black against Steve Heron from Liechtenstein, who is 11 or 12 and has a Fide rating of 1580.

Sicilian Accelerated Dragon
1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Nxd4 Nc6 5.Nb3!?
There are eight more-popular moves in ChessBase's 2021 Mega database, but the text has been played by grandmasters. The idea, normally, is to inhibit Black's thematic Accelerated pawn-thrust ...d5.
5...Bg7 6.Bd3?!
But this puts ...d5 back on the agenda. Normal is 6.Be2, while 6.Nc3 allows the controversial 6...Bxc3+!?
6...Nf6 7.Nc3 d5
There are 50 examples of 7...0-0 in Mega21 and just five of 7...d5, but Kjetil A Lie (2493), the strongest player to reach the position after 7.Nc3, chose the thematic text.
8.0-0 0-0
Komodo12.1.1 narrowly prefers 8...d4, but Stockfish13 likes castling.
9.Re1 e5
Both engines like 9...d4.
10.Bg5 d4 11.Nd5 Be6 12.Nxf6+ Bxf6 13.Bxf6 Qxf6
Position after Black has connected rooks
It might be thought White is doing well as Black's fianchettoed bishop has been exchanged, but White has few prospects of exploiting the holes around the black king. Meanwhile Black has more space in the centre and the more-active bishop. The engines agree Black is better.

Opening Lessons from Basel IV

IN round four I had white against Maximilian Ponamarev from Germany, who is 15 or 16 and has a Fide rating of 2017.

Sicilian ...e6
1.e4 c5 2.Nf3 e6 3.g3 Nc6 4.Bg2 g6?!
This has been played by many grandmasters, including Svidler, Kamsky and Liberzon, but is probably a mistake, as I hope to show.
The main move in ChessBase's 2021 Mega database is 4...Nf6, when the main line continues 5.Qe2 d5 6.exd5 Nxd5 7.0-0 Be7 8.Rd1, when Komodo12.1.1 reckons White has a slight edge, but Stockfish13 is less sure.
5.d4
It is easy for Black to carelessly forget White still has this option even though it was not exercised at move three.
5...cxd4
This is the main move, but Svidler has also tried 5...d5, when 6.exd5 exd5 7.0-0 cxd4 8.Nxd4 was nice for White in Mihail Kobalia (2614) Peter Svidler (2723), Chess.com Blitz 2020 (1-0, 43 moves).
6.Nxd4 Bg7
This natural-looking move is the engines' choice but, after White's reply, Black is in big trouble.
Eliezer Malzman (-) - Vladimir Liberzon (2555), Israeli Championship (Tel Aviv) 1978, saw 6...a6 7.0-0 Bg7 8.c3!? (8.Be3 seems better) Nge7, when Malzman played the surely too-slow 9.Ne2 and drew, but the engines reckon White has the upper hand after 9.Be3 or 9.Nxc6.
Svidler chose 6...Qb6!? in a 2012 blitz win against Magnus Carlsen, but the engines' reckon the latter's reply 7.Nxc6?! throws away much of White's advantage. Instead they like the much more popular 7.Nb3, when Stockfish13 rates the white position as already positionally won, although Komodo12.1.1 'only' gives White the upper hand.
7.Nb5
Taking advantage of the holes in Black's set-up.
7...Nf6?
Most popular in Mega21 is 7...Qa5+?! 8.N1c3 Bxc3+?! 9.Nxc3, but the engines strongly dislike the whole concept (an old rule-of-thumb says that when you have a bad bishop, you should not swop off your good one).
The engines reckon Black's best chance lies in sacrificing a pawn with 7...d5!? 8.exd5 exd5 9.Qxd5 Qe7+ 10.Qe4 Be6, but agree White is better (much better, according to Stockfish13).
8.Nd6+
This is good enough to cement White's advantage, but even better seems to the engines' 8.e5!?, the point being 8...Nxe5 9.Qd6 wins material for White. Best play, according to the engines, continues 9...Qa5+ 10.N1c3 Nc4 11.Qc7! 0-0 12.Qxc4.
8...Kf8 9.Nc3 a6
The engines suggest 9...Ne8, albeit with a large advantage for White.
10.0-0 Ne8 11.Bf4 Nxd6 12.Bxd6+ Kg8 13.Kh1!?
This may be too slow. I rejected 13.f4 because of 13...Qb6+ 14.Kh1 Qxb2, which is Komodo12.1.1's choice, but both engines give White a large advantage after 15.Rf3.
13...Bf8
Eduard Fomichenko (2357) - Elena S Brineva (2139), Poltavskaya (Russia) 2005, saw 13...h6 14.f4 with a strong attack for White (1-0, 29 moves).
Komodo12.1.1 at first reckons White only has a slight edge after 13...b5, but comes to give White the upper hand (Stockfish13 reckons White is winning).
14.e5 Bxd6 15.exd6?!
The engines prefer 15.Qxd6, meeting 15...Qf8 with 16.Na4, and if Black exchanges queens (I wanted to keep queens on, which is why I played the text), both engines give White a positionally won game.
15...b6 16.Bxc6!?
This may be best but the position is no longer so clear.
16...bxc6 17.Qf3?!
The engines do not like this, but are unsure as to how White should proceed - suggestions include 17.f3!?, 17.Kg1!?, 17.Qd2 and 17.Qd3.
Position after White connects rooks
White retains an edge, according to the engines, but the important part of the analysis is earlier in the play when I think I have demonstrated why ...g6 at move four is dubious (but Svidler apparently disagrees, so who are you going to believe?).

Opening Lessons From Basel III

IN round three I had black against Jeremias Stark, a Swiss aged 11 or 12 with a Fide rating of 1599.

Sicilian Accelerated Dragon
1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Nxd4 Nc6 5.Nxc6!?
An unusual choice, but this was my eighth time facing it, and I have twice played it myself.
5...bxc6
Against juniors an interesting choice might be 5...dxc6!? True, White can get an edge with 6.Qxd8+, but then Black has achieved the first rule-of-thumb of playing against juniors - get the queens off.
6.Nc3!?
White's normal idea is to play 7.Qd4, but the little-played text is preferred by the analysis engines Stockfsih13 and Komodo12.1.1.
6...Bg7 7.f3?!
Passive and weakening. It is by no means clear White will need this move. The normal follow-up to 6.Nc3!? is to continue development with 7.Bc4.
7...d6
I misjudged 7...Nf6 8.e5, not liking the pawn-sac 8...Nd5!? and underrating the simple retreat 8...Ng8, which the engines reckon favours Black.
8.Bf4!?
This does not look right. The obvious square for this bishop is e3, while the engines again like Bc4.
8...Qb6 9.Na4!?
Awkward-looking, but the engines only marginally prefer 9.Rb1.
9...Qa5+ 10.c3 Be6 11.Bd3
The engines want White to play the aggressive 11.b4!?, reckoning 11...Qc7 12.Qd2 Qb7 (White was threatening 13.Nc5) 13.Bd3 is at best only slightly better for Black.
11...Nf6 12.0-0 0-0
Position after Black has castled
Black has connected rooks, and the opening can be thought of as over. The engines give Black a very small edge.

Opening Lessons From Basel II

IN round two I had white against Anuar Tureshbayev from France, who is nine or 10 and does not have a Fide rating.

French Irregular
1.Nc3!?
This can have independent meaning but can also be used as a transpositional device.
1...d5 2.d4
The independent 2.e4 is the most-popular move by far, at least in ChessBase's 2021 Mega database, reaching a position that can arise, but rarely does, from a Scandinavian: 1.e4 d5 2.Nc3!?
2...e6 3.e4 c6!?
I have called this an irregular variation of the French Defence, but the position more often comes about from a Caro-Kann move-order: 1.e4 c6 2.d4 d5 3.Nc3 c6!?
4.Bd3
More popular are 4.Nf3 and 4.e5, but the text has been chosen by strong players, as has Stockfish13's pick, 4.a3!?
4...dxe4 5.Nxe4!?
Offering a promising gambit. Blackburne in 1880 preferred 5.Bxe4 Nf6 6.Bg5 Be7 7.Bxf6 in a simul win.
5...Qxd4
Stockfish13 and Komodo12.1.1 approve of this principled decision, but they agree White has an edge.
6.Nf3 Qd8
All nine games in Mega21 feature this retreat, but 6...Qb6!? is worth investigating. The engines come to view the moves as of approximately equal value.
7.Qe2!?
Holding back on where to develop the dark-square bishop and on whether to castle short or long.
7...Nf6 8.Nxf6+
Known moves are 8.Bg5 and 8.Bf4, but the engines prefer the text.
8...Qxf6
The engines prefer 8...gxf6!?, one line given by them running 9.0-0 Qd5!? 10.Nh4!? Nd7 11.Be3 Ne5, when they reckon White has a slight edge.
9.Bg5?!
Reckless. The engines give White the upper hand after 9.c3.
9...Qxb2 10.0-0
Position after White castles
With one side having connected rooks, the middlegame can be thought of as starting. Stockfish13 gives Black a slight edge after 10...Nd7, but Komodo12.1.1 reckons White has full compensation for the sacrificed pawns.

Opening Lessons From Basel

IN the first round I had black against Cyrill Speiser, a Swiss aged 16 or 17 who did not have a Fide elo but had a national one of 1320.

Sicilian Accelerated Dragon
1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Nxd4 Nc6 5.Nc3
For many years the refutation of Black's move-order, which began as the Hyper-Accelerated Variation of the Sicilian but transposed into a 'merely' Accelerated Variation, was supposed to be 5.c4, setting up a Maróczy Bind. The point was that if Black failed to 'force' Nc3 by playing an early ...Nf6, White should punish the omission by clamping down on the centre.
Modern thinking, I believe, holds that while the Bind gives White a long-term slight edge, defensive techniques have improved to the extent that Black should be reasonably comfortable. Similar views are often expressed about the Exchange Variation of the Queen's Gambit.
However, it is one thing for defensive techniques to have improved at elite levels, quite another for the same thing to have happened among club players.
Nevertheless, it is not every white who revels in the type of positional play the Maróczy usually entails, which is perhaps why there are almost 29,000 examples of the text in Chessbase's 2021 Mega database and just over 21,000 examples of 5.c4 (but the latter scores 57%, seven percentage points more than 5.Nc3).
I suspect the most important thing is to play what you feel most comfortable with, as is often the case unless one move can be shown to be seriously faulty.
5...Bg7 6.Nf3!?
What is White's idea?
*****
*****
*****
*****
*****
Much more popular in Mega21 are 6.Be3, 6.Nb3!?, 6.Nde2!? and 6.Nxc6!? All five moves have been played by grandmasters.
The idea of the text, which, at least in Mega21, only goes back to 1982, is presumably to interfere with Black's normal Accelerated plan of getting in ...d5 without spending a tempo on ...d6.
The drawback is that the white king's knight has spent three tempi getting to f3, from where it blocks the white f pawn, which often advances to f4 in the Sicilian.
6...Nf6
Also popular is 6...d6, which concedes the point about ...d5 but argues Black has little to fear since White has spent time manoeuvring the king's knight to what is arguably not its best square.
7.Bd3?!
Not only is this passive, but it seems to run contrary to the spirit of 6.Nf3!? More popular in Mega21 is 7.Bc4.
Note that 7.e5? runs into 7...Ng4, but the analysis engines Stockfish13 and Komodo12.1.1 point out a bizarre trap in 8.Ng1!? Ngxe5? 9.f4, when the black king's knight is a gonner. However, after 8.Ng1!? the engines reckon 8...d5!? 9.exd6 Bd4!? is strong for Black.
7...0-0
The thematic 7...d5!? would be a novelty, at least in Mega 21, and also probably good.
8.Bf4?!
A strange-looking move, perhaps hoping to get a knight into c7. Most popular in Mega21 is 8.0-0, when the position, according to the engines, is more-or-less equal.
8...d5
Getting this move in without first having to play ...d6 is a main reason - probably the main reason - Accelerated players 'risk' the Maróczy.
9.exd5 Nxd5 10.Qd2?
This should drop a pawn, but Black is also much better after 10.Bd2 or 10.Nxd5.
10...Nxf4?
Winning the bishop-pair, but Black can win a pawn with 10...Nxc3 11.bxc3 Qa5.
11.Qxf4 Bxc3+?!
Giving up the bishop-pair in return for inflicting structural weaknesses, but the engines' 11...Qb6 seems better.
12.bxc3 e5?
Not paying enough attention to the weak squares around the black king. The engines' 12...Qa5 is better.
13.Qh6 f6?!
This allows a drawing combination, and anyway may be inferior to 13...Qf6.
14.Bxg6!?
The opening is effectively over as objectively Black should now play 14...hxg6 and accept a draw by repetition. Instead I played on with 14...Qe7?!, although the game was eventually drawn.

Back Home

GETTING through checkin (a short queue) and security (no queue) at Zürich airport was a breeze.
Heathrow Terminal 2 was, if anything, even easier - from my flight touching down to getting through customs, collecting my luggage and joining an Underground train, just 25 minutes passed.

Reflections On Basel

EFFECTIVELY my trip to Basel became a glorified weekend swiss in that I played one game on day one and two games on days two and three.
All of my opponents were juniors, and it is probably fair to assume they have spent the past year or more improving online while their over-the-board ratings remained stagnant.
So what bearing does that have on my tournament performance of losing six Fide elo? 
Certainly my draw with a 2017 was a decent result, although I should have won the game after my opponent went seriously wrong in the opening.
But I was fortunate that one of my draws was with an opponent who had a Swiss elo of 1320, but no Fide rating, and it is hard to see anything creditable in that performance.
So it can be argued I was lucky not to lose more rating points, but on the other hand was unlucky to meet an all-junior field.
However, the bottom line is that my Fide rating will be going down.
I have not looked at the games in any great depth yet, but I have the following impressions:
1. I generally outplayed my opponents in the openings. This conforms with the view that juniors may be very booked up on sharp and fashionable lines, but can struggle with older theory.
2. I was thoroughly outplayed in middlegame tactics.
3. It is not possible to draw any conclusions about our respective endgame strengths - I won the only ending I reached, but by then I already had a large advantage.
THREE GOOD THINGS ABOUT BASEL AND THE TOURNAMENT
1. The city's old town has lots of interesting-looking bars and restaurants, including at least three Irish pubs.
2. Public transport, in the form of trams and buses, is excellent, and is free for hotel guests.
3. Playing conditions at the tournament were spacious, with good lighting.
THREE BAD THINGS ABOUT BASEL AND THE TOURNAMENT
1. Prices are often shocking, even for a Londoner, with a single and not-very-flavourful espresso typically costing about £4, and a half-litre of standard keg beer costing around £8.
2. Basel is not a normal tourism destination, so its attractions are limited if you are not into eating and drinking.
3. The city is easy to get to from Zürich airport, but overall for most people it is a long journey for a four-day tournament (assuming your opponents turn up for every round).

Good News ... Bad News

AFTER playing juniors in my first five games at Basel, I was paired with a grown-up for the sixth and final round today ... but my opponent, from Portugal, failed to show.
That meant I finished on 3.5pts (+1=3-1 and a default), which saw me lose exactly six Fide elo.
Meanwhile, in the early hours this morning, when I could not sleep, I watched some baseball, using the breaks between innings to fill in my passenger locator form for my return to England.
This included booking a covid Day 2 test, which set me back £75.

Basel Round Five

FACED my fifth junior this afternoon in round five of the Basel tournament. He is 11 or 12 years old and registered with Liechtenstein.
Steve Heron (1580) - Spanton (1814)
Sicilian Accelerated Dragon
1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Nxd4 Nc6 5.Nb3!?
Position after 5.Nb3!?
*****
*****
*****
*****
*****
The main idea of this move, as I understand it, is to restrain ...d5, which is Black's thematic equalising move in the Accelerated Dragon.
5...Bg7 6.Bd3?!
But this blocks the white queen's action along the d file.
6...Nf6 7.Nc3 d5 8.0-0 0-0 9.Re1 e5
The analysis engines Stockfish13 and Komodo12.1.1 like 9...d4.
10.Bg5 d4 11.Nd5 Be6 12.Nxf6+ Bxf6 13.Bxf6 Qxf6
Black has lost the fianchettoed bishop, but White is unlikely to be able to exploit the holes around the black king.
14.Nc5 Bc8
The engines like 14...Nd8!?
15.Be2 Qh4 16.Bb5 Qe7 17.Nd3 Bd7 18.Qf3 Rac8 19.Qg3 a6?
Black has a tiny edge, according to the engines, after 19...Nb8 20.Bxd7 Nxd7.
20.Bxc6 Rxc6 21.Qxe5
I had missed the strength of this move.
21...Re8?
Probably best, according to the engines, is 21...Qxe5 22.Nxe5 Rc7 23.Nxd7 Rxd7, although Black is a pawn down without compensation.
22.Qxd4 Rxc2?
And this makes Black's situation even worse.
23.Nb4 Rc5
What else? Nd5 is a huge threat.
24.Nd5 Rxd5 25.Qxd5 Bc6 26.Qb3 Qh4
Hoping to conjure up a swindle, but the odds are against it.
27.f3 Re5 28.Qd3 Rh5 29.h3 Qg5 30.Rad1! Kg7
Not 30...Rxh3? 31.Qd8+ Qxd8 32.Rxd8+ Kg7 33.gxh3.
31.Qd4+ f6 32.Qd8 Qe5 33.f4!? Qxb2?
This allows a mate in three, but 33...Qxf4 34.Qe7+ Kh6 35.Qf8+ Kg5 36.Rf1 Qe5 37.Qd8 creates the threat 38.Qd2+.
34.Qe7+ Kg8 35.Rd8+ 1-0

Basel Round Four

ARRIVED at the clinic for my covid antigen test earlier than I needed to, and wished I had arrived even earlier as I got tested 10 minutes before my appointment was due.
By a stroke of luck, the tram that goes to the chess venue also passed very near to the clinic, so I arrived at the board for round four of the Basel Tournament 'only' 17 minutes late.
My opponent was a junior from Germany, aged 15 or 16.
Spanton (1814) - Maximilian Ponomarev (2017)
Sicilian 1...e6
1.e4 c5 2.Nf3 e6 3.g3 Nc6 4.Bg2 g6?!
Perhaps it is presumptuous of me to say so, but this move, which has been played by many strong players, including Svidler and Kamsky, is probably a mistake, as I hope will become clear.
5.d4 cxd4 6.Nxd4
How should Black proceed?
*****
*****
*****
*****
*****
6...Bg7
Grandmasters have tried many different moves, but it is doubtful if any is fully satisfactory.
The text is most-popular in ChessBase's 2021 Mega database.
Svidler chose 6...Qb6, but the analysis engines Stockfish13 and Komodo12.1.1 reckon White is much better after 7.Nb3 (Kamsky's 2270 opponent played 5.0-0, but still managed to draw).
I thought Black should perhaps try 6...a6, but it has to be said Black's position looks very suspicious.
7.Nb5
The point behind why I believe ...g6 at move four is dubious. Having said that, Komodo12.1.1 reckons White 'only' has a slight edge. Stockfish13, as is often the case in its assessments, is more enthusiastic for the side with an advantage.
7...Nf6?
I thought Black should try 7...Qa5+ 8.N1c3 Bxc3+ 9.Nxc3, which turns out to be the most-popular line in Mega21, but the engines reckon White is positionally winning.
The engines suggest Black should sac a pawn with 7...d5!? 8.exd5 exd5 9.Qxd5 Qe7+ 10.Qe4 Be6, which was seen in a Russian blitz game between two players rated just under 2500. The engines reckon White is only slightly better.
8.Nd6+
Not bad, but the engines much prefer 8.e5!?, the point being 8...Nxe5 9.Qd6, when the engines reckon best is 9...Qa5+ 10.N1c3 Nc4 11.Qc7! 0-0 12.Qxc4, leaving White up a knight for a pawn.
8...Kf8 9.Nc3 a6 10.0-0 Ne8 11.Bf4
MP in the postmortem suggested 11.Nxe8 Qxe8 (the engines prefer 11...Kxe8) 12.f4. The engines reckon best is 11.Be3, but all three moves leave White much better.
11...Nxd6 12.Bxd6+ Kg8 13.Kh1!?
Preparing f4, but this never comes, and MP said, bearing in mind what happens in the game, that Kh1 may be a mistake. Certainly it may be too slow. If 13.f4, Komodo12.1.1 gives the continuation I was worrying about, viz 13...Qb6+ 14.Kh1 Qxb2, but both engines reckon White is much better after 15.Rf3.
13...Bf8 14.e5 Bxd6 15.exd6
The engines much prefer 15.Qxd6, I rejected it because after 15...Qf8 White cannot retreat the queen without dropping the e pawn, and I felt White's advantage was bigger with queens on. However the engines reckon 16.Na4 Qxd6 17.exd6 is very good for White.
15...b6 16.Bxc6!?
This may be best, but the position is unclear.
16...dxc6 17.Qf3?!
But this seems to throw away much of White's already-diminishing advantage.
17...Bb7?!
This does not seem best, but again the engines are unsure, flitting between 17...Ra7!?, 17...Qxd6 and 17...Kg7.
18.Kg1?
Scared of shadows. White has the upper hand, according to the engines, after 18.Rad1.
18...Qxd6 19.Ne4 Qe7 20.Qc3
Not 20.Nf6+?? Kg7.
20...f5!
A committal move, but if the knight retreats, Black's worries are over.
21.Nf6+!
This may look suicidal, but White has resources to emerge with at least equal chances.
21...Kf7 22.Rad1 Rad8
MP rejected 22...Rhd8! because of 23.Nxh7, but the engines continue 23...Rxd1 24.Rxd1 Rd8 with equality.
23.Rd7
Spectacular, perhaps, but not best as 23.Nd7! uses the same idea to reach a position in which White regains the pawn and has more pieces on the board to menace the black king (after 23...Rhe8 24.Nxb6).
23...Rxd7 24.Nxd7 Rd8
Not 24...Qxd7?? 25.Qxh8.
25.Nxb6 c5 26.Nc4 Qc7 27.Re1 Rd5?
As MP pointed out in the pm, this should lose. The engines reckon White has a slight edge after 27...Rd4.
28.Ne5+?
Missing the winning 28.Qh8.
28...Kg8 29.Qe3 Rd4 30.f3 Bd4!? ½–½
MP offered a draw, and I accepted as I could not see a way to an advantage. However the engines reckon White is well on top after 31.c3. I am fairly sure I thought 31...Ra4 was a good answer, but the engines give 32.Rd1 as winning.

Basel Round Three

COMPLETED a hat-trick of junior opponents this afternoon when I faced a Swiss aged 11 or 12 in the third round of the Basel tournament.
Jeremias Stark (1599) - Spanton (1814)
Sicilian Accelerated Dragon
1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Nxd4 Nc6 5.Nxc6!? bxc6 6.Nc3!?
There are more than 1,400 games in ChessBase's 2021 Mega database with the move 6.Qd4, but the little-played text is preferred by the analysis engines Stockfish13 and Komodo12.1.1.
6...Bg7 7.f3?!
This seems to be more weakening than anything.
7...d6
I rejected 7...Nf6!? because of 8.e5, but the engines reckon Black is better after 8...Ng8.
8.Bf4 Qb6 9.Na4
This looks awkward, but the engines only marginally prefer 9.Rb1.
9...Qa5+ 10.c3 Be6 11.Bd3 Nf6 12.0-0 0-0 13.c4!?
The engines prefer 13.Be3, although then Komodo12.1.1 continues 13...c5 14.c4.
13...Nd7 14.Bd2 Qc7
I seriously considered the pinning 14...Qa6, but rejected it because of the reply 15.Qc2?!, missing that 15...Nb6 costs White a pawn after 16.Nxb6 Qxb6+ or 16.Nc3 Bxc4. I think I somehow thought White could meet 15...Nb6 with 16.c5?, but then very good for Black is 16...Qxa4 17.cxb6 Qxc2 18.Bxc2 Bxb2.
15.Bc3?!
Black is only slightly better, according to the engines, after a move such as 15.Qe2.
15...Rab8?!
Strong is 15...Bxc3 16.Nxc3 Qb6+ 17.Rf2 Ne5 as 18.b3? fails to 18...Qe3.
16.b3 Ne5?!
The engines prefer 16...Nc5 17.Bxg7 Kxg7 18.Nxc5 Qb6, although they reckon it is at best a small edge for Black. In this line 17.Nxc5 Bxc3 18.Nxe6 fxe6 is better for Black, according to the engines, presumably because, although there are opposite-coloured bishops, the black bishop has much more freedom.
17.f4
Now White is better, according to the engines.
17...Nxd3 18.Qxd3 Bxc3 19.Nxc3 f5!?
Trying to open lines for the bishop, but Black's pawn-structure becomes compromised.
20.Rad1 fxe4 21.Qxe4 Bf5 22.Qe3!?
Komodo12.1.1 quite likes this move, but I felt the coming exchange of queens favours Black as a knight and queen often combine well in the middlegame while, after the queens come off, Black is left with the only piece (apart from the kings) that can move diagonally.
22...Qb6 23.Qxb6?!
Improving the black pawn-structure seems unnecessary, although at first the engines are happy with this capture.
23..axb6 24.Rde1 Rfe8 25.Ne4 Ra8 26.Rf2 h6 27.h3 Kf7 28.Ng3!?
A strange move, at least to me, but the position remains equal, according to the engines.
28...Bd7 29.f5 g5 30.Nh5 Ra5 31.g4 b5!?
White gets an outside passed pawn after this but it is a long way from the queening square and meanwhile an exchange of pawns gives Black's bishop more scope.
32.cxb5 Rxb5 33.Ng3 Rd5 34.Rb2?!
A puzzling move. Almost any other reasonable move keeps the position equal.
34...Rd3 35.Kh2 c5 36.Ne4?!
White is very close to equal after 36.Rf2, according to the engines.
36...Bc6?!
Missing the chance to get rid of the backward e pawn with 36...e6 or 36...e5.
37.Nf2 Rf3 38.Ne4?!
Probably better is 38.Re6 although Black is fine after 38...h5.
38...Rb8 39.Ree2?
Black is better after 39.Rbe2 Rb7, according to the engines, but the text runs into big trouble.
39...Rb4 40.Nd2 Rff4
Even better, according to the engines, is 40...Rc3!?, when the white king is suddenly looking rather vulnerable, eg 41.Nf1 h5 42.gxh5 Rh4 43.Re3 Rc1 44.Rf2 Rxh5 with continuing pressure.
41.Nc4?!
Better, according to the engines, is 41.Kg3 or 41.Rc2, although they much prefer Black.
41...Bb5
41...Rf1?! looks vaguely threatening but is harmless.
42.Rbc2
The engines reckon slightly better is 42.Rbd2!?, but Black still wins a pawn and is much better.
42...Bxd4 43.Rxc4 Rbxc4 44.bxc4 Rxc4 45.a3 h5?!
This is OK but unnecessarily complicating.
46.gxh5 Rf4?
Much better is 46...Rh4 with a large advantage.
47.Kg3?!
Objectively better is 47.h6 Rh4 48.Re6, although Black still has an advantage after 48...c4.
47...Rxf5?
...Rh4 is still much better.
48.Rf2 e6
How should White proceed?
*****
*****
*****
*****
*****
49.Rxf5+?
The pawn-ending is lost for White, despite having passed pawns on the a and h files, so something else should have been tried, eg 49.a4, but then 49...c4 is very good for Black.
49...exf5 50.h4?!
A better try is 50.a4 but 50...c4 51.Kf2 c3 52.Ke2 f4 etc wins. Also losing in this variation is 51.a5 c3 52.a6 c2 53.a7 c1=Q 54.a8=Q Qg1+ 55.Kf3 Qh1+.
The game finished:
50...gxh4+ 51.Kxh4 c4 52.a4 c3 53.a5 c2 54.a6 c1=Q 55.a7 Qf4+ 56.Kh3 Qe3+ 57.Kh4 Qf2+ 58.Kh3 Qxa7 0-1

Basel Round Two

FACED another junior this morning, and could discover little about him except he is French, aged nine or 10, does not have a Fide rating, and drew with a 1939 in round one.
Spanton (1814) - Anuar Tureshbayev (-)
French Irregular
1.Nc3 d5 2.d4 e6 3.e4 c6!?
Irregular, to say the least, but it has been played by grandmasters, and there are 525 examples of 3...c6!? in ChessBase's 2021 Mega database.
4.Bd3 dxe4 5.Nxe4!?
Speculative, but playable.
5...Qxd4 6.Nf3 Qd8 7.Qe2
Freeing d1 for a rook, and holding back on the dark-square bishop until Black has shown more of his hand.
7...Nf6 8.Nxf6+ Qxf6 9.Bg5?!
Throwing a second pawn on the fire, but Stockfish13 and Komodo12.1.1 reckon White has the upper hand after 9.c3.
9...Qxb2 10.0-0 Qb6 11.Rab1
The engines prefer 11.Ne5.
11...Qc7 12.Rfd1 Be7 13.Qe4?!
The engines like 13.Qe3 and 13.Bxe7.
13...Bxg5 14.Nxg5 h6 15.Nf3 Nd7 16.Rd2 Nf6 17.Qh4 0-0 18.Rbd1 Bd7 19.g4!?
Black has connected his rooks and remains two pawns up, so I felt I had to do something or else I would be without compensation for the material minus.
19...Qf4 20.Be2 Rad8 21.Rd4 Qc7 22.g5 hxg5 23.Nxg5 e5
How should White proceed?
*****
*****
*****
*****
*****
24.Rd6?
The engines give 24.Bd3! Rfe8 25.Bc4 with an unclear position.
Another better try than the text is 24.Ne4!? as 24...exd4? 25.Nxf6+ gxf6 26.Bd3 Rfe8 27.Qh6 is a draw. However, after 24.Ne4!? Black has 24...Nxe4 25.Rxe4 Be6 with what the engines reckon is a clearly winning position.
24...Bf5 25.Rxd8
The desperate 25.Nxf7? fails to 25...Kxf7.
25...Rxd8 26.Rxd8+ Qxd8 27.Bc4
27.Qh8+!? Kxh8 28.Nxf7+ Kg8 29.Nxd8 wins back a pawn, but the engines continue 29...Bc8, when the white knight is surely doomed.
27...Bg6?
Much better is 27...Qd1+ 28.Kg2 Nd5.
28.Nf3?
Retreating the knight is always likely to be hopeless, but here it misses 28.Bxf7+! Bxf7 29.Qh8+ Kxh8 30.Nxf7+ and 31.Nxd8, when White has equalised.
28...Qd1+ 29.Kg2 Be4 30.Qh3 Qxc2?
Greedy. Black can simply swop off into an ending two pawns up, but even better is 30...g5 etc.
31.Qc8+ Kh7 32.Qh3+ Kg6 33.Qg3+ Kh6 34.Qh4+ Kg6
Disastrous for Black would be 34...Nh5?? 35.Qg5+ Kh7 36.Qxh5+ Kg8 37.Qxf7+ and 38.Qh5#.
35.Qg3+ Kh7 36.Qh3+ Kg6 37.Qg3+ Kh6 38.Qh4+ Kg6 39.Qg3+ Kh6 40.Qh4+ ½–½

Basel Round One

Cyrill Speiser (?) - Spanton (1814)
Sicilian Accelerated Dragon
1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Nxd4 Nc6 5.Nc3 Bg7 6.Nf3!?
Unusual, but it has been played by grandmasters.
6...Nf6 7.Bd3
Not 7.e5? Ng4.
7...0-0 8.Bf4?!
White is more-or-less equal after 8.0-0, according to the analysis engines Stockfish13 and Komodo12.1.1.
8...d5 9.exd5 Nxd5 10.Qd2?
Both 10.Bd2 and 10.Nxd5 are better.
How should Black proceed?
*****
*****
*****
*****
*****
10...Nxf4?
Missing the win of at least a pawn after 10...Nxc3 11.bxc3 Qa5.
11.Qxf4 Bxc3+?!
The engines' 11...Qb6 is probably better.
12.bxc3 e5?!
The engines prefer 12...Qa5.
13.Qh6 f6?!
Probably better, and certainly more practical, is 13...Qf6.
14.Bxg6!?
There had been a somewhat chaotic start to the first round, and I had not been able to find out who my opponent was (but I knew I had to be in the top half of the draw). My opponent and I exchanged names, and I told him my rating, but he said he could not remember his (and ratings were not displayed with the pairings, nor were they otherwise available, except online, which was awkward as phones are not allowed at the venue).
By the time CS played 14.Bxg6!?, the  lower-rated player on the board next to me (I was sat at the end of a row, so there was only one board next to me) had already lost a piece and was still rushing his moves (within a few minutes he would be mated, or possibly he resigned when faced with mate-in-one - I did not notice which).
Since these were the circumstances, I felt justified in taking the risk of playing on.
14...Qe7?!
14...hxg6 15.Qxg6+ Kh8 16.Qh6+ etc is dead-drawn.
15.Be4
The problem with my decision is not so much that Black is a pawn down - after all, White has doubled and isolated c pawns - but the fact that the black king is dangerously exposed. I should also have taken into consideration that my opponent, a junior, was not rushing his moves, unlike the much-younger junior sat next to me.
15...Be6 16.0-0 Kh8?
Trying for more than the position offers. Best, according to the engines, is 16...Qg7, although Stockfish13 gives White at least the upper hand after 17.Qe3 (Komodo12.1.1 reckons White only has a slight edge).
17.Nh4
Threatening 18.Ng6+. Black's reply is forced.
17...Kg8 18.f4 Qg7
I felt I had to offer an exchange of queens.
Not 18...f5? 19.Bxc6 (19.Rf3!? is also strong) bxc6 20.Rae1 e4 21.Re3.
I also did not like the look of 18...exf4 19.Rxf4, when Black's king is in huge danger.
19.Qxg7+
If 19.Qh5!? then not 19...Bg4? 20.Bxh7+! Instead Black should probably play 20...Qf7, when White is either obliged to allow an exchange of queens or has to withdraw his queen from the vicinity of the black king.
19...Kxg7 20.Rad1 Rfd8
Likely the wrong rook, but almost certainly better than 20...Bxa2?!, when 21.Nf5+ Kh8 (21...Kg8? 22.Rd7 is horrific for Black, eg 22...Rf7 23.Nh6+) 22.Nd6 is strong for White.
21.Rb1 Rab8
I rejected 21...Rd7 because of 22.Rxb7!? Rxb7 23.Bxc6 Rab8 24.Bxb7 Rxb7 25.fxe5 fxe5, but the engines reckon White is only slightly better. I missed that 26.Re1 can be met by 26...Kf6 (or 26...Rb5 for that matter).
22.fxe5 fxe5
I rejected the engines' choice, 22...Nxe5!?, because of 23.Rxb7+ (better than 23.Bxb7, according to the engines) Rxb7 24.Bxb7, but the black knight gets a decent outpost, and Black's pieces are better coordinated than White's.
23.Nf5+ Kh8
I thought this was forced because of 23...Kg8 24.Bxc6 bxc6 25.Ne7+ Kg7 26.Nxc6, but 26...Rxb1 27.Rxb1 Rd2 28.Nxe5 Rxc2 29.Rb7+ Kf6 30.Nf3 Rxa2 31.Rxh7 is not completely clear-cut, despite White's two-pawn advantage, as Black's outside passed pawn is a fast runner.
However, the engines prefer the text as they reckon 23...Kg8 is well-met by White maintaining the pressure with 24.a4 or 24.Ne3.
24.Nh6 Kg7 25.Nf5+ Kh8 26.Nh6 Kg7 27.Nf5+ ½–½
A severe case of rating-itis; of course White should play on.
(I discovered after the game that CS does not have a Fide rating, but has a Swiss rating of 1320.)

Testing ... Very Testing

SPENT much of this morning trying to book a rapid antigen test, which I have to take in the three days before I am due to fly back to London on Wednesday.
This proved surprisingly difficult, with many venues fully booked for next week, and others having no suitable time slots, bearing in mind that I have two games on both Sunday and Monday and do not want to leave my test until Tuesday afternoon.
I think I have managed to get somewhere, although 9.10am on Monday is hardly ideal - I will need to take a taxi afterwards to the venue and am unlikely to arrive for when the morning round starts at 9.30am.

Free Basel

I FLEW to Basel two days before the tournament began so as to have a free day to explore the city and get my bearings.
The venue, the Landgasthof Riehen, is some four miles out of town, so today I practised catching the number 6 tram, which stops right outside the hotel.
It was just as well I did in that I caught the right tram, in as much as it was a number 6, but it was coming from Riehen instead of going to it.
Never mind - hotel guests in Basel get free public transport, so it cost me nothing to get off after a few stops, cross the street and catch a number 6 heading in the right direction.
The venue, outside of which the number 6 stops

An intriguing-looking church opposite the Landgasthof Riehen - unfortunately it was locked
I had a late breakfast of an espresso and a slice of apple pie at a small cafe in Riehen, which cost me 9.80 Swiss francs (before a tip) - that is about £8.
I walked back into town, which is easy to do as you can follow the tram tracks until you find an interesting point to turn off.
The route is very flat and mostly urban, but there were some sights worth recording.





Thursday 15 July 2021

Basel City

MY flight landed at Zürich airport almost exactly on schedule at 5.15pm.
There was a delay disembarking, but I breezed through customs with no one asking to check my passenger locator form or my proof of being fully vaccinated.
Indeed the only minor problem I had was explaining why I was visiting Switzerland - my pronunciation of "Schachspiel" was insufficient, but "chess" got the job done.
I had time at the airport for a coffee and to buy a roll and a drink to have on the train, which, with one change at Zürich's main station, got me to Basel before 7.30pm.
And that left time for me to find the old town and get my first impressions in the evening gloom.






Swiss Swizz

I TOLD in an earlier post how I got an exchange rate of 1.2367 Swiss francs for a pound at the Victoria XE on Monday.
Since I paid £300, a quick calculation shows I received 371 Swiss francs.
Today at Heathrow Terminal 2 the rate from Travelex is 1.0066, meaning £300 would buy just under 302 Swiss francs.
In other words, the Victoria rate is 22.85% better than the airport rate.

So Far, So Good

ARRIVED at Heathrow Terminal 2, long before checkin for my flight was officially due to open, but I was allowed to proceed anyway.
Security took well under five minutes to pass through, and I am now sat at the Big Smoke Taphouse & Kitchen drinking what purports to be a double espresso but is more like an americano - I knew everything could not run smoothly.

Swiss Bound

TODAY I face the prospect of navigating my way through check-in and security at Heathrow, followed by customs at Zürich.
If the experience is anything like my trip from Gatwick to Crete last month, things should go relatively smoothly.
The problems, if there are any, are more likely to arise on returning to the UK and having to get through customs at Heathrow.
The good news is that Terminal 2, which is where I am travelling from and to, seems to be less affected by delays than Terminal 5
Then again, recent reports of long queues concerned Terminal 5 departures rather than arrivals, so maybe the Curse of Heathrow can strike anywhere at anytime.

Mind The Gap

MY participation at tournaments in Basel (Jul 17-20) and Gateshead (Aug 26-30) means there is a roughly five-week gap to fill chess-wise.
In pre-covid times I would have probably solved this with a series of weekend events in the UK.
A search of the calendar at the English Chess Federation supplies two promising candidates: Oxford (Aug 7-8) and Ilkley (Aug 21-22), although the former is likely to be a junior-fest.*
I am also considering another longer tournament somewhere in Europe, but will hold fire on any such decision until nearer the time as I fear more countries will soon return to banning visitors from Britain.
*Incidentally,  the word likely is an anagram of Ilkley!

Heading North

LOOKS like Tim Wall's Northumbria congress will be my first over-the-board chess on home soil since a London League game in March 2020.
It is being held in August from Thursday 26 to Monday 30 at the Marriott Hotel, Gateshead.
I have entered the challengers, which is U2000. Depending on whether you put your trust in Fide or the ECF, I am either roughly in the middle of the pack (Fide rating 1814) or one of the favourites (ECF rating 1998).
There are five other sections: two round-robin invitationals, a masters (open), a major (U1750) and a minor (U1500).
The time control is all moves in 90 minutes, with a 30-second increment.
Round one on the Thursday is at 6.30pm, with two rounds on each of the other four days at 10am and 3pm.
The list of entries, and more details of the tournaments, can be found at https://northumbriamasters.com/entries/

Swiss Prep Update

MADE it to Victoria, where the best rate I could get for £1 was 1.2367 Swiss francs.
This compares with an online mid-rate of 1.257754 from XE, so I did not do too badly.
Around the corner was a Post Office exchange bureau offering a miserly 1.186.
On the way I called in at the Daunt bookshop in Cheapside, without finding anything I wanted, but at Waterstones in Trafalgar Square I bought Kapka Kassabova's travel book Border - A Journey To The Edge Of Europe (Granta £9.99).
I am still little more than halfway through Eric Newby's Round Ireland In Low Gear, so I should have enough reading to tide me over my trip to Basel, especially as I expect much of my time to be taken up with chess. 

Swiss Preparations

I INTEND walking from my home in Spitalfields, East London, to Victoria station in Westminster to buy Swiss francs today.
The best exchange rates that I know of in the UK can usually be found at the bureaus around the station (but definitely not in the station itself).
Not all of them had reopened the last time I checked, but with any luck I should get a reasonable deal.
I also want to call in at Foyles or somewhere similar to buy a book to take on my trip to Basel, which is now just three days away.

Swiss Watching

MOST experienced chess players know roughly how swiss pairings work at a chess tournament.
In each round players meet opponents on the same score as themselves, whenever possible.
Colours alternate, again whenever possible, and the golden rule is that you do not play the same opponent twice.
The system is named after a tournament held in Zürich in 1895 that used a format devised by a local teacher, Julius Müller. Before then chess tournaments were either all-play-alls or knockouts.
According to ChessBase writer André Schulz, the format may have been first used by Müller six years earlier at another tournament held in Switzerland.
I was prompted to look this up after posting yesterday about an upcoming swiss I am playing in at Basel.
As is quite well-known, the swiss system is used by organisers of other games, including bridge and Scrabble.
According to Wikipedia, it will also be used in football's Champions League from 2024:

On 19 April 2021, UEFA announced that from the 2024-2025 season, the UEFA Champions League will start using the Swiss system. What was previously known as the “group stage” (the stage in between the “qualifications stage” and the “knock-out stage”) will become one unified 36 team group. Each team will play 10 different opponents, 5 at home and 5 away. The matches in each round will be set using the Swiss system algorithm with the top 8 teams automatically moving up to the knockout Round of 16 stage, teams placed 9th to 24th will play a two-legged playoff (with teams placed 9th to 16th holding a home field advantage) in order to qualify for the Round of 16 stage.

But do not expect to get into meaningful discussions with football fans about the ins and outs of swiss pairings.
In fact Uefa will use what it is calling the "Swiss model," which is certainly not what chess players regard as a swiss.
There will be 36 teams, with each playing 10 opponents, five at home and five away. But the key point is the fixtures will be announced at the start of the competition rather than being decided after each round of games.
The eight best teams will advance to a knockout stage, where they will be joined by eight winners from play-off games between the teams that finish ninth to 24th.
More details will be released nearer the time, but the main effect from a chess viewpoint may be to cause even more confusion among non-players about how a swiss-style chess tournament works.

A Swiss swiss

I MENTIONED yesterday I have entered the Basel schachfestival, which is being held from Saturday 17 to Tuesday 20 at the Landgasthof Riehen.
I was too late to book accommodation at the venue, which is four miles from Basel's main train station, so I am staying in town at an Ibis Budget.
If it is anything like the Ibis Budget at Bradford, West Yorks, it will be good value for money, especially as my stay apparently comes with a pass for free public transport in the area.
The congress is being run as one big swiss, with a 4pm round on the Saturday, 9.30am and 3pm rounds on the Sunday and Monday, and a 9.30am round on the Tuesday (prize-giving, should it prove relevant, is 2.30pm on Tuesday).
The time control is 40 moves in 90 minutes, then a 15-minute 'windback', with a 30-second increment from move one.
So far there are 138 entries, which is fairly near the venue's maximum of 150, and there are plenty of countries represented by a lone soul.

Here is a selection of interesting rules and observations:

Before going to the tournament venue, please remember to bring at least 5 (1 per round) protective masks (certified surgical masks, nowadays also available in supermarkets), or a visor, and a personal pen to fill out the Contact Tracing Form and note your moves on the game forms.

- A lateral, front and rear distance between the chessboards of at least 1,5 m will be ensured
- The tournament room will be regularly aired
- Chessboards and pieces will be disinfected after each round or completed game
- A bottle of hand disinfectant will be available at the entrance to the room
- There will be a waste container for used masks at the exit of the game room
- The tournament director will measure the body temperature of the participants before checking in. Unfortunately, people with a body temperature of over 37,4 ° C will not be admitted to participate in the tournament.

This is one of the first tournament since the Covid-19 emergency. Together, we will succeed it if everyone does his/her part. So that we can finally continue to play real tournaments and opponents "in person" in the future.
Have fun and a "virtual hug"!
