*My round-three opponent did not have an ECF rating so I have used his Fide rating to calculate my ECF performance.
I begin this blog after getting back into league chess following many years' absence due to work. My post-job status also means I am able to play more tournament chess. My new club in London is Battersea and my first game for them is on Thursday September 14, 2017. I start with a Fide rating of 1858, an ECF grade of 169 (=1968 elo) and an ICCF correspondence rating of 2267. My current Fide is 2009, my ECF is 1955 and my ICCF is 2325.

London System
1.d4 d5 2.Nf3 Nc6 3.Bf4 Bg4 4.e3 e6 5.Be2 Bd6 6.Bg3 h5!?
The mainline in ChessBase's 2023 Mega database runs 6...Nge7 (6...Nf6 is also popular) 7.Nbd2 0-0 8.0-0 with a slight edge for White, according to Stockfish16 and Komodo14.1.

7.Nbd2
Carrying on with normal London System development seems perfectly reasonable.
7...h4 8.Bxd6 cxd6!? 9.h3 Bf5 10.c3 Nf6 11.Qa4 Ne4 12.c4 dxc4
This is one of the points of 8...cxd6!? - when White breaks with c4 Black can capture and still have as many central pawns as White.
13.Bxc4 a6 14.d5?!
White should probably withdraw the queen or the bishop.
14...Nc5 15.Qa3 exd5 16.Bxd5 Nb4
How should White meet Black's triple-threat of a forking check on c2, a check on d3 and the win of a bishop? |
*****

*****
*****
17.Nd4
White could also calmly castle, but 17.0-0!? Nxd5 18.e4 Bxh3!? 19.exd5 Bf5 seems to leave White with insufficient compensation for a pawn, eg 20.Rfe1+ can be met by 20...Kf8, after which the black king is probably safe enough.
17...Qf6
The engines reckon 17...a5!? gives Black the upper hand.
18.Bf3 Nbd3+
Not 18...Qxd4? 19.exd4 Nc2+ 20.Kd1 Nxa3 21.dxc5, but possibly better is 18...Ncd3+ and if, as in the game, 19.Kf1 0-0 20.Nxf5+ Qxf5, White does not have the game's 21.b4.
19.Kf1 0-0 20.Nxf5 Qxf5 21.b4

21...Qe5?
Black may have a slight edge after 21...Ne6, and if 22.e4? then 22...Qe5, eg 23.Nb3 Rac8 24.Rd1 Nfe4 with what the engines reckon is a wining position. They suggest 22.Ne4 but agree 22...d5 may give Black a small pull.
22.Rb1 Nxf2 23.Kxf2 Qg3+ 24.Ke2 Ne6 25.Ne4 Qg6 26.Rhd1 Rad8 27.Rb2 Rfe8 28.Kf1!?
A simple solution - the white king is now safe, and Black is bishop-for-pawn down. The game went on another 27 moves but White was always winning.

8.d5
This has been played by Mateusz Bartel (2653) and Levon Aronian (2773), easily the strongest players to reach the position in ChessBase's 2023 Mega database, but Stockfish16 and Komodo14.1 prefer 8.0-0 and 8.Nc3.
8...Nb8
The engines slightly prefer 8...a6, when they reckon only 9.Bd3 keeps the game equal.
9.Nc3 d6 10.0-0 a6 11.Bd3 b5!?
Expanding, but without the tempo that would have been gained if the white light-square bishop were on a4 or c4.

17.Bxb5??
Completely misevaluating White's compensation. The engines give 17.a4 Rxc6 (not 17...b4? 18.Nd1 a5 19.Ba6) 18.axb5 axb5 19.Bxb5. disagreeing, as before, over whether White stands better or the position is equal.
17...axb5 18.Qxb5 Qc7 19.Nd5 Bxd5 20.exd5 Rb8 21.Qc4 Qa5
The engines point out 21...Nxd5!? 22.Qxd5 Bxb2.
22.Rd1?
The position is a lot trickier after 22.c7 Rbc8 23.b4!?, eg 23...Qxd5 24.b5 is equal, according to the engines. They give 23...Qa8, reckoning Black is on top.
22...Rxb2 23.Bd4 Rb4 24.Qc2 Nxd5 25.Bxg7+ Kxg7 26.Rab1 Rxb1 27.Rxb1 Qc3 (0-1, 35 moves)
Leicester 2
LEICESTER previously hosted the British chess championships in 1960, when the main event was won by Jonathan Penrose for the third year running. He would go on to win the British title a further seven times.

New London
1.d4 d5 2.Bf4 e6 3.e3 Bd6 4.Bg3 Nf6 5.Nf3 b6
Castling is the main move by a huge margin in ChessBase's 2023 Mega database.
6.Bd3 Bb7
Stockfish16 and Komodo14.1 prefer controlling e4 rather than aiming for an exchange of light-square bishops with 6...Ba6!?
7.Nbd2 Nbd7 8.Ne5!?
There are 15 games with this move in Mega23. It scores 53%, compared with 445 for the 25 examples of 8.c3.
*****
*****
*****
*****
8...Bxe5!?
A rule-of-thumb has it that when you have a bad bishop, in this case Black's light-squared one, you should not swop off the other bishop. The engines reckon the game is equal after 8...0-0 or 8...Ne4!?
9.dxe5 Ne4 10.Bxe4!?
9.dxe5 Ne4 10.Bxe4!?
This was played in both Mega23 games to reach the position. The engines marginally prefer 10.Nxe4.
10...dxe4 11.Qg4
This is why whites have captured with the bishop - two black pawns are en prise.
11....Qe7
The engines prefer 11...Rg8!?, and if 12.Nxe4 then 12...h5 13.Qf4 g5 14.Qf3 Kf8!?, claiming Black is at least equal.

12.0-0-0?
Maximilian Berchtenbreiter (2384) - Alexander Bertagnolli (2343), Austrian Team Championship 2016, went 12.Bh4 f5 13.exf6 gxf6 14.0-0-0 with maybe a slight edge for White, according to the engines (1-0, 41 moves).The engines like 12.Qxg7!? 0-0-0 13.Qh6, claiming at least a slight edge for White, although I do not believe many human players would want to grab a pawn in such a way. However, it is certainly better than the text as after ...
12...h5 13.Qh3 0-0-0
... Black is winning (13...g5 was also strong).
14.f4 exf3 15.Nxf3 g5 16.Nd4
The engines prefer 16.Rd4!?, the point being 16...g4?! lets White avoid the worst with 17.Qh4. However the simple 16...Rde8 leaves Black well on top.
16...h4 17.Be1 Nxe5
Not only winning a pawn, but threatening the devastating ...g4.
18.e4 c5 19.Qa3
Pinning the c5 pawn, but the relief is only temporary.
19...Qc7 20.Ne2 Rxd1+ 21.Kxd1 Rd8+ 22.Kc1 Bxe4 23.Qe3
There is nothing better, according to the engines.
23...Bxg2 24.Rg1 Qd6
Extracting the bishop with 24...Bc6 is possible as 25.Rxg5?! runs into 25...Nf3.
25.Nc3
It only gets worse for White after 25.Bc3?! Nf3.
25...Bf3
Renewing the threat of a back-rank mate.
26.b3 f6 27.Rf1 Qc6 28.a4 Kb7 29.Kb2 a5 30.Nb1
Possibly not the best, but the state of White's position can be gauged from the fact Stockfish16, at least for a while, wants White to play 30.Bxh4!?
30...c4 31.Bc3 cxb3 32.cxb3 Rd3 33.Qc1
Not 33.Qf2? Rxc3! 34.Nxc3 Nd3+ etc.
33...Rd5 34.Qe3 g4!? 35.Qh6 Nd3+ 36.Ka1 e5 37.Qxh4 Rc5??
Both 37...Nc5 and 37...Rd7 leave Black the equivalent of being more than a rook up (more than two rooks, according to Komodo14.1).
38.Qh7+ Qc7 39.Qxd3
*****
*****
*****
*****
Black has two pawns for a knight, and the slightly safer king in a middlegame with opposite-coloured bishops, the latter usually favouring whoever can get the initiative. The engines give White a slight edge.
39...e4 40.Qd4!? f5
It may be better to throw caution to the winds and grab the h pawn, but best, according to the engines, is defending f6 with 40...Rc6, although they prefer White.
41.Bd2?!
The engines reckon White is much better after 41.Bb2, which unties the white queen and knight.
41...Qf7?
Black equalises with 41...f4, with ...e3 to come, according to the engines.
42.Nc3!?
The engines reckon 42.Rc3 is even stronger.
42...Qxb3
There is nothing better.

43...Qe6?
Better is 43...Ka6!?, but completely equalising, according to the engines, is 43...e3!, eg 44.Qd7+ Kb8, after which White has to take a draw by perpetual check, or 44.Bxe3 Rxb5!, after which again White has to take a draw by perpetual check as 45.axb5?? loses to 45...Qa3+ 46.Kb1 Be4+.
After the text the white bishop comes decisively into the attack.

Clocking In
CLOCK towers are out of fashion in these days when owning a timepiece is no longer regarded as a luxury.
What is now a relatively open space, forming a junction for five major streets, used to be occupied by an agricultural market and assembly rooms, the latter being divided into shops in 1805.
But there was a time when household clocks, let alone personal watches, were rare.
Many progressive cities and towns, especially those with active business communities, built centrally placed clock towers in the 18th and 19th centuries.
Some were simple affairs, merely containing bells that were rung at key times, for example to call people to work.
But towers with working clocks were considered the ideal, becoming symbols of civic pride as well as letting people know the time of day.
Leicester's example, officially called the Haymarket Memorial Clock Tower, is slightly unusual in that it was conceived as a way to improve an area.
Leicester's clock tower ... smart as well as practical |
The shops came to be seen as a bit of an eyesore, and other businesses claimed they were an obstruction to Leicester's increasing commercial activity.
A campaign succeeded in 1862 in having the shops demolished, and within a few years the market was moved, leaving a wide open area that, perhaps ironically, businesses complained was difficult for people to cross because of increased traffic.
Rumours of a clock tower, or something similar, planned for another part of Leicester led to a subscription being started, with some £872 - worth about £600,000* today - raised in a year.
A further £1,200 was contributed by Leicester Corporation, and the clock tower was built in 1868 as the centre of a pedestrian island that in the early 1900s was flanked by tram lines.
The Memorial part of the clock tower's name refers to its statues of local worthies, mostly long-forgotten wool merchants but including Simon de Montfort, who today is best-known, if known at all, for leading baronial opposition to Henry III, but in the 13th century was noted as a Jew-persecutor.
Leicester City Council extensively renovated the site in the early 21st century, and it now forms the centre of a largely pedestrianised precinct.

King's Indian Attack
1.e4 c5 2.Nf3 e6 3.d3 d5 4.Qe2!?
There are 731 examples of this move in ChessBase's 2023 Mega database, where it scores 60%, which is 10 percentage points more than the 3,229 games with 4.Nbd2.
4...d4!?
This is sixth-most popular in Mega23.

5.g3
This is much more common than 5.e5!?, although Stockfsh16 and Komodo14.1 reckon the two moves are of roughly equal value.
5...Nc6 6.Bg2
Here the engines much prefer 6.e5!?, which scores 71% in Mega23 - 18 percentage points more than the text.
6...e5 7.Nbd2 be7 8.Nc4 Bf6!?
A peculiar square for a bishop, but the engines are not too unhappy with it.
9.a4 Be6 10.b3 h6 11.Ba3 b6 12.h4 Qd7 13.Qd2 Nge7 14.Ng1!? g6 15.Bh3 Nc8 16.Qe2!?

16...Nd6 17.Nxd6+ Qxd6 18.Bxe6 Qxe6
*****
*****
*****
*****
Black has a bad bishop, but White's bishop, although technically good in that most white pawns are on light squares, has little scope. Black has more space in the centre, and Komodo14.1 reckons Black has a tiny pull, although Stockfish16 calls the game completely equal.
19.f4 h5 20.0-0-0!?
Stockfish16 strongly dislikes this, preferring 20.Bc1, but Komdo14.1 reckons the two moves are of approximately equal value.
20...Qg4
Sotckfish16 gives something like (its evaluations of various moves change frequently) 20..a6!? 21.Rf1 Be7 22.f5 Qd7 23.g4 c4!? 24.Bxe7 Qxe7 25.bxc4 gxf5 26.exf5 Qa3+ 27.Kd1 Qxa4, after which both engines agree Black has at least a slight edge. However there were many alternatives for both sides along the way.

Tim Harding (1928 Fide*) - Spanton (1941 ECF/1800 Fide)
*****
Scotch Gambit/Giuoco Piano
1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4!?
There are 31,890 examples of this move in ChessBase's 2023 Mega database, where it scores 57% - two percentage points higher than the more popular 4.Nxd4.
4...Bc5!?
Black scores 45% with this in Mega23 - four percentage points lower than with the main move 4...Nf6, which reaches a position that also arises from the Two Knights Defence.
5.c3 Nf6
Very risky is 5...dxc3!? 6.Bxf7+! Kxf7 7.Qd5+, after which White regains at least the sacrificed bishop, eg 7...Ke8 8.Qh5+ Kf8 9.Qxc5+ d6 10.Qxc3 with clearly the better game.
The position after 5...Nf6 frequently arises from the Giuoco Piano via the move-order 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.c3 Nf6 5.d4 exd4 |
*****
*****
*****
*****
*****
6.e5!?
Stockfish16 and Komodo14.1 prefer this marginally - very marginally in the case of the former - over the much more common 6.cxd4.
6...d5
As is well-known, ...d5 is often the best reply in open games when White thrusts with e5.
7.Bb5
Trendy at the elite level in recent years has been 7.Be2!?, although the engines reckon 7...Ne4 is a complete equaliser. Not popular at the top is 7.exf6!? dxc4 8.fxg7 Rg8, which at first glance may look promising for White, but practice strongly favours Black.
7...Ne4 8.cxd4
*****
*****
*****
*****
8...Bb6
This is the mainline in modern times, although grandmasters also play 8...Be7 and especially 8...Bb4+. After the latter White usually offers the bishop-pair with 9.Bd2!?, when 9...Nxd2 10.Nbxd2 0-0 11.0-0 leaves White slightly better, according to Komodo14.1, although Stockfish16 is less sure.
9.Be3!?
More popular are 9.0-0 and especially 9.Nc3.
9...0-0 10.Nc3 Nxc3!?
Komodo14.1 likes this relatively rare continuation, but Stockfish16 prefers the main move 10....Bg4 or 10...f5.
11.bxc3 Ne7!?
Avoiding doubled pawns and preparing to contest the b1-h7 diagonal. The engines prefer attacking the white centre with 11...f6.
12.Bd3 Bf5 13.0-0 Qd7 14.Rb1!?
This useful-looking developing move may be a novelty. Several high-level games have seen 14.Nh4 Bxd3 15.Qxd3 f5, with advantage to White, according to the engines.
14...c6
The engines suggest 14...Rac8!? with the idea of breaking with ...c5.
15.Bg5 Bxd3 16.Qxd3 h6 17.Bc1
The engines reckon White should take the chance to swop off the bad dark-square bishop.
17...Ng6 18.h3 Bd8?!
This is probably too slow. The engines advocate 18...Rac8, again with the idea of trying to get in ...c5.
19.Nh2
White's unchallenged central space advantage, in a position in which the centre is unlikely to open soon, means he has time to launch a kingside attack.
*****
*****
*****
*****
19...b5
Freeing Black's pieces from having to defend the b pawn. The engines prefer sacrificing it with 19...Nh4 20.f4 Qf5!? After 21.Qxf5 Nxf5 22.Ba3 Re8 23.Rxb7 the black knight is active, but that is not sufficient compensation. If instead of giving up a pawn, Black tries 20...Nf5, White has 21.g4 and 22.f5 with promising play.
20.f4 f5 21.exf6 Rxf6 22.Ng4 Rf5 23.Ne3 Rf6
Not 23...Nxf4? 24.Qxf5 Ne2+ as Black gets nowhere enough for a rook after either 25.Kf2!? or 25.Kh2.
24.Ng4 Rf5 25.Ne3 Rf6
*****
*****
*****
*****
26.f5
White is winning, according to the engines.
26...Ne7
After 26...Nh4?! White can go after the knight immediately with 27.g3 Qd6 28.Ng4, but even stronger, according to the engines, is to first play 27.Bd2.
27.Ng4?!
This seems to let most of White's advantage slip. Best, according to the engines, is 27.Ba3!?, eg 27...h5 28.Rbe1 Nc8 29.g4 Rf7 30.gxh5!? Be7 31.Bc5 Nd6 32.Bxd6 Bxd6 33.Ng4 Raf8 34.f6 with a very strong attack.
27...Rxf5 28.Bxh6!? Bc7
Very bad is 28...gxh6?? 29.Nxh6+ and Nxf5(+). Black is also in trouble after 28...Rxf1+? 29.Rxf1 as in effect Black's active king's rook has been swopped for White's inactive queen's rook.
29.Rbe1 Raf8 30.Bc1 Rxf1+ 31.Rxf1 Rxf1+ 32.Kxf1!?
The engines reckon this is playable, but the king was safer where it was.
32...Nf5 33.Qf3?!
Probably better is 33.Ne5!?, or continuing to run to the queenside with 33.Ke1!?
33...Ng3+ 34.Ke1
It is perhaps too late to go back as 34.Kg1 can be met by 34...Qe6, eg 35.Bd2 Qg6 36.Qe3 Qb1+ 37.Qe1 Qf5!? 38.Nf2 Bd6 with continuing pressure.
34...Qe7+ 35.Qe3
The engines suggest 35.Kd1, but with a slight edge for Black (and with practical difficulties thanks to the exposed white king).
35...Ne4 36.Kd1 b4 37.cxb4?
This loses. White has to play 37.Kc2!?, according to the engines, but a tough defensive task lies ahead as White seems to have no counterplay.
37...Qxb4 38.a3?!
Best, according to the engines, is giving up the a pawn with 38.Qd3!? Qa4+ 39.Ke2 (39.Qb3 Qxd4+) Qxa2+ 40.Kf3, but Black is winning.
38...Qa4+ 39.Ke2
39.Ke1 Ba5+ is not an improvement.
39...Qc4+ 40.Kf3
Slightly better is 40.Kd1, but 40...Bd8!, among other moves, is deeply unpleasant.
40...Qf1+ 41.Nf2 Bg3 0-1

Orthodox Defence
MODERN Leicester is well-known for being multi-cultural, but just how multi was brought home to me when I saw a sign in the city centre for a Serbian Orthodox Church.
The sign behind protective church railings |
St George's was built from 1823-7 as an Anglican place of worship, but was taken over by members of the Serbian Orthodox confession in the 1980s.
It was renamed (slightly) as St George The Great Martyr, and the church's feast day moved from April 23 to May 6 to reflect the Gregorian calendar instead of the older Julian version.
The approach is very much what one might expect from a church built in the early 1800s |
Hard to tell whether these are genuine gargoyles (decorative waterspouts) or merely grotesques (decorative carvings with no functional purpose) |

23.c3
The engines reckon White should immediately go for kingside play with 23.Rf1!?, meeting 23...Bxb2 with 24.c3 with obvious compensation for a pawn.
23...c4
Vacating the c5 square for a knight is a typical idea in this type of position. Sometimes it is played as a sacrifice, but here it has the added bonus of establishing outposts at d3 and b3.
24.Qc2 Nc5 25.Nxc5 Qxc5 26.Bf2 Qc7 27.Qd2 Nd7 28.Bd4?!
Giving up the bishop-pair and allowing Black to emerge with much the better minor piece. The engines reckon 28.Re1 is at least equal.
28...Bxd4
As RdC pointed out in the postmortem, 28...Nc5 is possible as 29.Bxg7?! can be met by the zwischenzug 29...Nb3!, when 30.Qf2 Kxg7! leaves White under a lot of pressure as the white position is decidedly loose. But note that 30...Nxa1?! 31.Bf6 gives White a lot of compensation for an exchange. RdC rejected the whole line because of 29.Bxc5, after which Black will struggle to make progress.
29.Qxd4
The engines are unsure, but possibly better is 29.cxd4!?, taking away the c5 square from the knight.
29...Qc5 30.Rd1 b5 31.Kf2?
The engines reckon White has to play 31.axb5, albeit preferring Black.
31...Qxd4+
Even stronger, it seems, is 31...bxa4!?, not so much because it wins a pawn, I believe, but because of the weakness of b2, eg 32.Rd2 Qxd4+ 33.Rxd4 Nc5 34.Rxc4 Rb8, or 32.Be2 Qb5!? 33.Rd2 Nc5! 34.Bxc4 Qb6 35.Bd3 (or 35.Kf3 Re4) Nxd3+ 36.Rxd3 Qxb2+ 37.Rd2 Qb1 etc.
32.Rxd4
Capturing with the pawn deserved, as at move 29, serious consideration.
32...Nc5 33.axb5
*****
*****
*****
*****
33...axb5
We both thought 33...Nd3+ 34.Rxd3!? cxd3 35.bxa6 was promising for White. The engines disagree, but reckon 34.Kg3 axb5 35.b3 leaves White only slightly worse.
34.Be2 Ra8 35.Ke3
Not 35.Rd2?? Ne4+.
35...Ra2 36.Rd2 Na4
This looks natural, but White has a drawing resource. Best, according to the engines, is 36...g5!?, eg 37.fxg5 hxg5 38.Bd1 Kg7 39.Rf2 Ra1 40.Rd2 Rb1, after which White is horribly tied up.
37.Bd1 Rxb2?!
This only draws, as the engines realise apparently instantly. They suggest 37...Nc5 with continued probing.
38.Bxa4 Rxd2 39.Kxd2 bxa4

*****
*****
40.Kc2 g5 41.fxg5 hxg5 42.Kb2 Kg7 43.Ka3 Kf6 44.Kxa4 Ke5 45.Kb5 Kxd5
Black is still a pawn up, but only temporarily.
The game finished:
46.Kb4 Ke5 47.Kxc4 d5+ 48.Kc5 f6 49.Kc6 Ke6 ½–½
Saint Mary De Castro
NEXT to where Leicester Castle stood, and within the boundary of what was the castle's bailey (defensive enclosure), lies the church of St Mary de Castro.
Its name signifies, in Latin, that it was "of the castle," as opposed to a nearby abbey, St Mary de Pratis, or "of the meadow."
Consecrated in 1107 and greatly expanded less than 60 years later, St Mary de Castro probably began as a church after being converted from an already established college |
Canterbury Tales author Geoffrey Chaucer is believed to have wed Philippa Roet, a lady-in-waiting to Edward III's wife Philippa of Hainault, in the church in 1366.
Four-year-old Henry VI was knighted here in 1426 while the so-called Parliament of Bats - attendees were banned from carrying swords, and so armed themselves with stout wooden sticks - was held in the Great Hall of the castle.
As this photo by NotFromUtrecht on Wikipedia shows, the church had a spire until it was declared unsafe and was demolished in 2014 |

1.Nf3 Nc6!? 2.c4 e5 3.Nc3 g6 4.g3 Bg7 5.Bg2 d6 6.0-0 Nge7 7.a3 a5
This might seem like a fairly standard position from the English, but it occurs only five times in ChessBase's 2023 Mega database |

8.d4!?
IK afterwards said he was following a game of Tony Miles', but he almost certainly got his positions mixed. Stockfish16 and Komodo14.1 suggest 8.Rb1, 8.d3 and 8.e3, all of which have been played.
8...Nxd4 9.Nxd4 exd4 10.Nb5 Nc6 11.e3!?
Offering to make the pawn-sacrifice permanent.
The engines suggest 11.Bg5!?, when 11...f6 weakens the black kingside, while 11...Qd7 leads to complicated play, eg 12.Bh3!? Qxh3!? (12...f5 is possible, but weakening) 12.Nxc7+ Kf8 13.Nxa8 h5!? with a very unclear position.
*****
*****
*****
*****
11...d3!?
Returning the pawn but making it difficult for White to develop his queen's bishop.
11...dxe3 12.Bxe3 0-0 (almost certainly not 12...Bxb2?! 13.Bh6) 13.c5 gives White promising compensation, but the engines reckon is playable.
12.Qxd3 0-0 13.Rd1?!
This looks natural but fails to take into account the weakness of the c4 pawn. The engines suggest 13.f4 or 13.Qc2, although Stockfish16 gives Black a slight edge after either move.
13...Ne5 14.Qe2
The engines prefer 14.Qe4 or 14.Qc2.
14...Be6
Even stronger, according to the engines, is 14...Bg4 15.f3 Be6.
15.Rd4 Nc6 16.Rd2 Ne5 17.Bd5?!
If 17.Rd4 I was considering playing on with a pawn offer of my own, namely 17...Qe7!? The engines reckon Black has more than enough compensation after, for example, 18.Bxb7 Rxb8 19.Bg2 c6 20.Nc3 Rfc8. Another try is 17...c6!?, when both 18.Nxd6 and 18.Rxd6 can be met by 18...Qe7.
The engines reckon best is the passive 17.Rc2, but they prefer Black.
17...c6 18.Bxe6 fxe6 19.f4
White can save the knight and cover the f3 square with 19.Nd4, but the engines reckon both 19...Qf6 and 19...Qe7 leave Black well on top.
19...cxb5 20.fxe5 Bxe5 21.cxb5 Qg5
*****
*****
*****
*****
22.e4?
Missing the main threat contained in my last move. The engines suggest covering the back rank with 22.Rd1.
22...Bxg3! 23.Kh1?!
Not 23.hxg3? Qxg3+ 24.Qg2 Qe1+ 25.Kh2 Rf4 etc, nor 23.Qg2? Qe3+ 24.Kh1 Qe1+ etc, but probably best is 23.Rd1 Bf4+ 24.Kd1 Qh4, although Black emerges a pawn up and with much the safer king.
23...Rf2 24.Qxf2 Bxf2 25.Rxf2 Qxb5
*****
*****
*****
*****
White's extra rook and bishop are no match for Black's queen and two pawns. The engines reckon Black is the equivalent of more than a rook ahead.
26.Bh6 Qh5 27.Bd2 Qe5
Somewhat greedily going after another pawn. Much simpler is 27...Rf8.
28.Re1 Qxb2 29.Ref1 Qxa3 30.Bh6
*****
*****
*****
*****
30...d5 31.exd5 exd5 32.Rf7 Re8 33.Rg7+ Kg8 34.Rgf7 Qb4 35.Rf8+!?
The bishop-v-pawns ending arising after this is lost for White, but perhaps it is the best try.
35...Rxf8 36.Rxf8+ Qxf8 37.Bxf8 Kg8 38.Ba3 Kf7 39.Kg2 Ke6 40.Kf3 Kf5 41.Bc5 b5 42.h3 g5 43.Ke3 h5 44.Kf3 b4 45.Ke3 g4 46.hxg4+ hxg4 47.Bd6
The bishop cannot cope with four pawns - indeed, of all Black's possible moves, only 47...g3?? fails to win |
*****

47...b3
Bizarrely, the top move given by the Syzygy endgame tablebase is 47...a4!?, and if 48.Bxb4 then an only-move, 48...g3 wins, but I doubt if any human would play that way.
The game finished:
48.Ba3 g3 49.Kf3 g2 50.Kxg2 Ke4 51.Kf2 Kd3 52.Kf3 Kc3 53.Ke3 d4+ 54.Ke2 Kc2 55.Ke1 d3 0-1
Leicester Castle
THE original castle was a motte-and-bailey construction erected shortly after the Norman conquest of 1066.
Still existing, albeit reduced in height, is an earth mound (motte) upon which a wooden castle, properly called a keep, was built.
The lower-ground bailey, consisting of a wooden wall and ditch, inside of which was accommodation for the garrison along with other buildings, including stables, is long gone.
The wooden fortifications were soon replaced by stone, with the castle being expanded over the centuries despite partial demolition on the orders of Henry II after being used by his rebel sons in their revolt of 1173-4.
Just about all that survives is the Great Hall, disfigured by a modern facade, and Turret Gateway.
Approaching the two-storey Turret Gateway from the outside - it had a third storey, but that was destroyed in an election riot of 1832 |
The groove (centre-right) shows where the portcullis used to be raised and lowered |

So This Is Leicester
BACK in 2005 I walked from London to Edinburgh in 22 days.
Much of the early part of the route took me along the Grand Union Canal.
I remember taking the Leicester branch, but am fairly sure I turned off - the exact route was planned for me by a former member of the SAS - before reaching the city.
So it will be interesting to see what I missed back then as I had never been to Leicester before, nor have I since.
Today's first impressions are promising, helped by my hotel being less than five minutes' walk from the chess championships' venue at De Montfort University.
Not only am I very close, but, as I discovered this afternoon after arriving at my hotel, the short walk takes me through Castle Gardens.
As the name implies, Castle Gardens is on land that used to be part of Leicester Castle |
It is a pity the sun was not shining to bring out the best of the gardens, but they are attractive anyway |
The four-acre site is popular with dog-walkers and other locals who appreciate greenery just a few hundred yards from the city centre |
A Matter Of Taste
IF you enjoy photos of old chess players at closing ceremonies, you are in for a treat here.
Senior Championship Chess
AM traveling to Leicester today for the 65+ section of the British chess championships.
My 1800 Fide rating means I am seeded 39th out of 51 entrants.
The time control is 40 moves in 90 minutes, with 30 minutes to finish and a 30-second increment from move one.
There are seven rounds, which seem rather few for a championship. The start time is 14:30 from tomorrow through Saturday, and 10:00 next Sunday.

Book Prize
MY opponent in round six at Świdnica was so impressed by my play, and the analysis I showed him in our postmortem, that he insisted on fetching a book and presenting it to me.
I should add that he also said the book was useless to him as he could not read it.
His problem was not that the book, The Complete Chess Guide by FJ Lee and GHD Gossip, is in English, but that the notation is descriptive rather than algebraic.
Descriptive notation was all the rage in Britain, and in Spain for that matter, when this hardback was published by John Grant of Edinburgh in 1910 |
That is not a problem for me as I was brought up on descriptive, and I get a feeling of familiarity when I flick through the pages.
The book is divided into four parts: Chess Player's Mentor, Modern Chess Brilliancies, Guide To The Openings and Games At Odds.
No doubt it will mainly be of interest for its curiosity value.
For example, on page 10 in the first section, which is largely aimed at beginners, there is the DUMMY PAWN RULE, where it is stated:
When a Pawn has reached an eighth square, its player has the option of selecting a piece, whether such piece has been previously lost or not, whose names and powers it shall then assume, or of deciding that it shall remain a Pawn. This is the new "dummy" pawn rule laid down by the British Chess Association in case of a position where a player compelled to accept a piece would thereby lose the game; whereas, by refusing promotion to his Pawn, he could draw it. It is scarcely necessary to add that such positions, although possible, are exceedingly improbable, and do not occur in the course of a lifetime to the vast majority of Chess players. The "dummy" Pawn rule was stoutly opposed by the late Mr. Staunton as contrary to the spirit of the game and denounced by him as absurd. None the less, the law exists in this country, and must therefore be laid down amongst the other laws. In Italy, a plurality of Queens, denounced by Philidor, was not permissible.
For the life of me I cannot think of a situation in which promoting a pawn would lose a game, whereas leaving it as a pawn would mean a draw. Can anyone help?

8.Bg5!?
There are four more-popular moves in ChessBase's 2023 Mega database, especially 8.a3, but the text is marginally preferred by Stockfish16.
8...0-0 9.h3 h6 10.Bd2
Interesting is 10.Bxe7, the idea being to take control of d5.
10...Kh7 11.Kh2 Be6 12.Ne4?!
*****

*****
12...Qd7
Not 12...f5? 13.Neg5+! etc. Nevertheless White's 12th move is dubious as, provided Black avoids the trap, the knight is wasting time and encouraging Black to expand on the kingside.
13.e3 f5 14.Nc3 d5
Even stronger may be the engines' 14...e4!? 15.dxe4 fxe4 16.Nxe4 Bxc4.
15.cxd5 Nxd5 16.Nxd5 Bxd5 17.Bc3 Rad8 18.Qa4
*****

18...Bxf3!?
Other moves also preserve Black's advantage, but the text brings favourable simplification.
19.Bxf3 Nd4 20.Qd1
Not 20.Qxd7? Nxf3+ 21.Kg2 Rxd7 22.Kxf3 Rxd3.
20...Nxf3+ 21.Qxf3 Qd5 22.Qd1 b5!
The engines agree this is better than 22...Qxd3, after which White gets counterplay with 23.Qa4 or 23.Qb3.
23.Ba5 Rd6 24.Qc2 Ra6
The engines reckon even stronger are 24...b4 and 24...f4!?
25.b4!? Rc6?!
The engines much prefer 25...f4!?
26.Rac1?!
White more-or-less equalises with 26.bxc5, according to the engines.
26...Rfc8 27.Qe2 c4 28.dxc4 Rxc4 29.Rcd1 Qc6 30.Rd2
*****

*****
30...Rc1?!
This allows comfortable equality. Black is still better after 30...f4!? or 30...Rf8, according to the engines.
31.Rfd1 Rc2 32.Qd3 Qc4 33.Qd7!?
Simpler is 33.Qxc4 or even 33.Qxc2!?, eg 33.Qxc2!? Qxc2 34.Rxc2 Rxc2 35.Kg2 Rxa2 36.Rd7.
33...Qxa2 34.Bd8!?
Suddenly the black king is in danger.

34...Kg8?
The game is completely equal after 34...Qc4 or 34...R8c6, according to the engines.

35.Qe8+
Not 35.Qxc8 as after 35...Rxd2 White does not have a good discovery-move with the bishop, but the engines point out 35.Bf6! After 35...Bxf6 White wins with 36.Qxc8+, and after 35...Qf7 White has 36.Qxf7+ Kxf7 37.Rd7+ Kxf6 38.R1d6+ Kg5 39.Rxg7, eg 39...f4 40.exf4+ Kf5 41.Rf7+ Ke4 42.fxe5 Kxe5 43.Rxg6 with a large advantage. If in this latter line Black tries 40...exf4? then 41.Rgxg6+ Kf5 42.g4+ Ke4 43,Kg2 is even more convincing.
35...Kh7 36.Qd7 Qc4 37.h4!? f4!? 38.exf4 exf4 39.h5?!
The engines reckon 39.Rxc2 Qxc2 40.Rd2 fxg3+ 41.fxg3 is equal.
39...fxg3+ 40.fxg3
*****
*****
*****
*****
40...Qg4?? 0-1
That was the right idea, but the wrong execution. With 40...Qe4 41.hxg6+ Black is at least slightly better, according to the engines, after both 41...Qxg6 and 41...Kxg6!?
