I am in-between Tyson Fury and Mr T ... something of a long-time dream fulfilled.

Did I Miss A Draw?

ROOK endings are notoriously drawish, both in theory and in practice, but what do you think of the following position?

Black to make his 36th move in Thomas Brown (2068) - Spanton (1954), Hastings Masters Round Four

*****
*****
*****
*****
*****
Firstly, we can dismiss 36...Rxc6?? 37.Rh5+ as completely hopeless for Black.
In the game I played 36...Rd1+? 37.Kc2 Rd6 38.c7 Rc6+ 38.Kd3 1-0
But, as TB suggested afterwards, I should have tried 36...f3! The point is that 37.gxf3 Rxc6 brings about an example of the infamously drawn f&h-pawn ending.*
TB was not sure if the actual position on the board would be drawn, but the Nalimov endgame tablebase confirms the position is indeed drawn.
White could try 37.Rh5+ Kf4 38.Rh4+ Kg5 39.Rg4+ Kh5 40.gxf3, but again the f&h-pawn ending is drawn after 40...Rxc6.
So, yes, I did miss a draw (assuming I would have played it accurately).
*If you do not know about this, consult almost any general endgame book.

Endgame Escape

ESCAPED with a draw against a junior in round three of the Hastings Masters after trying too hard in a drawn position.

Black has just played 37...Rb7-b4 in Spanton (1954) - Cassie Graham (1889)

Thirteen moves earlier I had turned down a draw offer in a dead-equal position. Over the next few moves I gained a tiny edge, more cosmetic than anything, but then missed an initiative-gaining idea for my opponent.
In the diagram position, Black threatens ...d5 followed by a fork on ...d4.
I rejected 45.Rc4 because of 45...Rxc4 46.bxc4, but it turns out White's queenside pawns are much easier to defend than I thought.
Instead I chose …
45.Nf4?
… but after …
45...Nxf4 46.gxf4
… I was definitely on the back foot.
46...Ke6 47.Rd3 d5 48.Rd1 f6?!
A bit of a non-move that seems to throw away much of Black's advantage by, believe it or not, weakening Black's kingside. More on this later.
Definitely mistaken was 48...d4+? as White is fine after 49.Kd3, eg 49...Kf5 50.Re1, when 50...Kxf4?! allows dangerous counterplay with 51.Re7, so safest is probably 50...Rb7, when 51.Re4 holds.
My main analysis engines, Komodo9 and Stockfish9, reckon Black keeps the upper hand after 48...Kd6.
49.Re1?
Taking pressure off d5. Instead I should have tried the engines' 49.h5!?, which gives decent drawing chances, eg 49...gxh5 50.Rh1, or 49...c4 50.hxg6 hxg6 51.Rd4. Another line runs 49...g5 50.fxg5 fxg5 51.Re1, when 51...Rh4 52.Kd3+ Kd6 53.Re8 Rxh5 54.Ra8 seems to give sufficient counterplay.
Note that after 49.Kd6, the move 49...h5 is much less effective as an exchange on g6 does not leave Black with a weak g pawn.
49...Kd6?!
Almost certainly not aggressive enough. I feared 49...Kf5, when there does not seem any way for White to save the game. The text gave me a second chance to find the engines' …
50.h5!?
… and Black replied with the mistaken …
50...gxh5?
Also wrong was 50...g5? as White has 51.fxg5 fxg5 52.h6 Rh4 53.Rg1 with excellent drawing chances.
Best was the immediate 50...c4, although after 51.hxg6 hxg6 52.bxc4 Rxc4 53.Rg1 Rc3+ 54.Kd4 Rxf3 55.Rg4, Black still has some work to do.
51.Rh1 c4
A tempo too late.
52.bxc4 Rxc4 53.Rxh5 Rxa4 54.Rxh7
Black has a tiny edge, but White can draw without much difficulty.
54...a5 55.Ra7 Ra3+ 56.Ke2 Ke6 57.Ra6+ Ke7
Black cannot make progress. The remaining moves were:
58.f5 a4 59.Re6+ Kf7 60.Rd6 Rc3 61.Kd2 Rxf3 62.Rd7+ Ke8 63.Rxd5 a3 64.Ra5 a2 65.Ke2 a1=Q 66.Rxa1 ½-½
I was pleased to discover after the game that CG has an ECF of 178, so my grading will have edged up as a result of this game even as my Elo rating edged down.

Outplayed

SOMETIMES you have to hold your hands up and admit you were second-best.
Matthew Payne (2182) - Spanton (1954)
Hastings Masters, Round Two
1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Nxd4 Bc5 5.Nxc6
White's second-most popular choice, behind 5.Be3.
5...Qf6
A well-known intermezzo based on the threat of mate at f2.
6.Qf3!? bxc6!?
The last two moves might need some explaining to anyone not familiar with the Scotch Opening.
As I understand it, White is arguing that doubled f pawns are a price worth paying for exchanging off Black's well-placed queen. In addition, White would get pressure down the half-open g file, and anyway maintains a central space advantage.
Black's most popular reply is, as I played, 6...bxc6!? but there is no consensus about this among top players. Carlsen, for example, has played the text and 6...dxc6, while Kramnik has played the text and 6...Qxf3.
7.Nd2
This was first played as recently as 1995, according to ChessBase's 2019 Mega database, but it has quickly become White's top choice.
The old move, 7.Nc3, still has its adherents, with attacking players such as Morozevich among them.
7...Rb8?!
MP in the post-mortem could not understand the point of this.
Most popular is 7...d6 but I, somewhat unrealistically, hoped to get in ...d5, and did not want to spend a tempo on moving the d pawn forward just one square. I could not see any other useful move for Black, and so played the text as a semi-useful waiting move.
Interestingly, 7...Qxf3 is usually answered by 8.gxf3!?
8.Nb3 Qxf3 9.gxf3 Bb6
The bishop looks aggressively posted here, but retreating along the other diagonal may have been more prudent. I seriously considered 9...Be7, while MP suggested 9...Bd6.
10.Rg1 g6 11.Be3
MP played this to enable quick castling, but the move is not liked by the analysis engines Stockfish10 and Komodo9, who give 11.a4.
11...Bxe3 12.fxe3 Ne7 13.0-0-0 0-0 14.h4
This looks natural, but the engines reckon White is much better after 14.Rg5!?, the idea being to pressure Black's weakened queenside.
14...d6
The move I had been trying to avoid, but it is hard to find a good alternative. 14...d5?!, for example, leaves Black very inflexible on the queenside.

Black's forces are confined to three ranks, and White now found an interesting way to use his extra mobility to exploit Black's weaknesses

*****
*****
*****
*****
*****
15.e5!?
It takes the engines quite some time to see the force of this move.
15...dxe5?!
This greedy response seems to play into White's hands. The engines prefer 15...Nf5 or 15...Rd8, but in each case with White having the better game.
16.e4
The point of White's sacrifice. Black is in a bind with few prospects for active play.
16...f5?
A rash, and bad, bid for freedom.
I did not like 16...Be6 because of 17.Nc5, when Black will be hard-pressed to defend his numerous pawn weaknesses.
Stockfish10 suggests 16...Re8, but after 17.Nc5 Kf8 18.Rd3 White clearly has more than enough compensation for the pawn.
Komodo9's 16...Kg7 17.Nc5 Re8 is met by 18.Nd7, when White gets his pawn back and Black is still left with weaknesses.
17.Bc4+ Kg7 18.Nc5 fxe4 19.fxe4 Rf4 20.Rd8 Rf8?
Losing more-or-less instantly.
I had to try 20...Rxh4, when 21.Be6?? may even be better for Black after 21...Rb5. But White has several strong continuations, including 21.Rf1 Rf4 22.Rxf4 exf4 23.Re8 Kf6 24.Nd3 with the threat of e5+
21.Rxf8 Kxf8 22.Rf1+ Ke8 23.Bf7+ Kf8 24.Bxg6+ Kg7 25.Rf7+ Kg6 26.Rxe7
White has won his pawn back, and Black has even more weaknesses than earlier.
The game finished:
26...Rb5 27.Nd3 Bb7 28.Rxc7 a5 29.c4 Rb6 30.c5 1-0

30 New-Years In Hastings

AM back in Hastings for the 30th consecutive time of playing in the congress over New Year.
Spanton (1954) - Holger Witt (1567)
Hastings Masters, Round One
1.d4 e6 2.e4 d5 3.Nc3 Bb4 4.e5 Ne7 5.Bd2 c5
By two minor transpositions, we have reached the starting point of the Bogoljubov Variation of the French Winawer.
6.a3
This virtually forces the win of the bishop-pair, but more popular is 6.Nb5, when the knight might go to d6.
6...Bxc3
Just about possible is 6...Ba5?! but White scores massively with the simple 7.dxc5.
7.Bxc3 cxd4 8.Bxd4
The mainline sees White keeping the bishop-pair with 8.Qxd4 Nbc6 9.Qg4.
8...Nbc6 9.Nf3 Nxd4 10.Nxd4 a6!?
This may be a new move.
Three previous games of mine featured 10...Nc6, with me scoring a win and two draws against lower-rated opposition.
11.Bd3 Nc6 12.Nf3 Bd7 13.0-0 0-0 14.Qe2 b5?!
White must be better anyway, but further shutting-in Black's light-square bishop is very unlikely to be right.
15.b4!?
Clearly double-edged as the c pawn is now weak.
15...Qb6

Has Black allowed a Greek Gift sac?

*****
*****
*****
*****
*****
16.c3
Definitely not 16.Bxh7+?? Kxh7 17.Ng5+ as the Black king can come out at g6 or h6 without putting itself in serious danger. White's rooks are a long way from helping in the attack, and the e5 pawn is weak.
16...h6 17.Rfd1 Rac8 18.Rac1 Rc7
My main analysis engines quite like the odd-looking 18...Be8!? Komodo9 for some time assesses the position as almost equal, but Stockfish10 reckons White has the upper hand. However, the engines' evaluations eventually merge at slightly better for White.
19.Bb1 Rfc8
The engines prefer 19...Ne7, but with White for choice.
After the text, both players' pieces are largely bunched on the queenside, but White can more easily switch to the other wing.
20.Qd3 g6 21.h4 Be8
21...Ne7, 21...Rf8 and 21...h5 are all suggested by the engines, but in each case with White having a substantial advantage.
22.h5 Ne7 23.Nd4
Even stronger seems to be 23.Qd2 Kg7 24.hxg6.
23...Nf5
The only hope, according to the engines.
24.Nxf5?!
I seriously looked at 24.hxg6 with the idea of 24...Nxd4 25.gxf7+, which is indeed very strong, although 24...fxg6 keeps the game going. In the end I settled for a line that is easier to calculate but is almost certainly not so good.
24...gxf5 25.g4
25.Qg3+? does not achieve anything. Indeed, it invites later trouble down the g file.
25...Rc4 26.gxf5 Rf4??
A blunder that loses immediately.
I expected 26...Rg4+ 27.Kf1, when the engines give 27...exf5 with advantage to White after 28.Qxd5 or 28.Qxf5, but still with lots to play for.
27.Qg3+ 1-0

Have Yourself A Coulsdon Little Christmas

PLAYED at Coulsdon over the weekend, scoring +2=1-2.
I was pretty disappointed with my play, not least at missing numerous tactics, not helped by my old sin of playing too quickly.
My performance was enough to cost me 5.8 elo, and I felt as though I deserved to have lost more.
My mood was not improved on putting the games into ChessBase this evening and discovering even more errors than I had suspected.
And yet, when I came to check my ECF grading performance, I found I performed at 172.4 - comfortably more than my ECF grade of 167 ...

I'm In The Money

Spanton (1940) - Marcel Gil Vega (1977), Benidorm U2000, Round 10
Caro-Kann, Classical Variation
1.e4 c6 2.d4 d5 3.Nc3
I have been playing the Panov-Botvinnik (3.cxd5 cxd5 4.c4) more often lately, but I lost to GV in the same tournament last year, albeit with colours reversed, and decided something more solid was in order.
3...dxe4 4.Nxe4 Bf5 5.Ng3
An old favourite of mine is 5.Bd3!? Critical is 5...Qxd4 6.Nf3, after which Black's best is probably 6...Qd8, when 7.Qe2 gives White reasonable compensation.
5...Bg6 6.Nf3 Nd7 7.h4 h6 8.h5 Bh7 9.Bd3 Bxd3 10.Qd3 e6 11.Bd2
This modest-looking development has become White's most-popular move, the idea being to prevent ...Qa5.
11...Ngf6 12.0-0-0 Qc7 13.Kb1 0-0-0 14.Ne4 Nxe4 15.Qxe4 Nf6 16.Qe5
Part of a plan to get the queens off. This may be an OK idea in itself, but does not fit well with spending a tempo on Kb1.
16...Bd6 17.Qa5 Qxa5
17...b6 18.Qa6+ Kb8 looks risky for Black.
18.Bxa5 b6 19.Bd2 Rd7 20.Be3!?
After the game, GF said this was very bad, but I do not think White has anything to fear from an exchange of Black knight for White bishop.
20...Ng4 21.c3 Rhd8 22.Kc2 c5 23.dxc5?!
This could have led to a difficult position for White. More solid was 23.Rh4 or Stockfish9's suggestion 23.Rde1.

Black to play his 23rd move and gain an advantage

*****
*****
*****
*****
*****
*****
23...Nxe3+
The obvious reply, but better was 23...Bxc5!, when f2 is exposed as a weakness for White. Stockfish9 and Komodo9 give the main line as 24.Rxd7 Rxd7 25.Rh4 Nxe3+ 26.fxe3 Bxe3 27.Rg4 f5 28.Rg6, when Stockfish9 reckons White has almost full compensation for the pawn, but Komodo9 has Black as slightly better. I find it hard not to agree with Komodo9.
24.fxe3 Bxc5
At first glance, the coming ending might seem better for Black as he has bishop v knight in a position with unbalanced pawn majorities. But the key point is that Black will find it hard to generate a passed pawn from his restricted kingside majority.
25.e4 f6 26.Rxd7 Rxd7 27.Rd1
Rook and bishop usually work together better than rook and knight, so it seemed sensible to get all the majors off the board.
27...Rxd1 28.Kxd1 Kd7 29.Ke2 b5?!
Surely playing on the wrong side of the board.
30.Kd3 b4?
Very much the wrong idea, but I fail to exploit the mistake.
31.c4?
Generally it makes sense in this type of ending to leave the pawns of the player with the bishop on the same coloured squares as the bishop, but after the text it is difficult for White to make progress.
Instead there was a sure advantage in 31.cxb4 Bxb4 32.Kc4, when White can activate his majority while Black's is stymied, and Black cannot get at White's kingside pawns.
31...Kd6 32.b3 Bb6 33.Ke2 Bc5 34.Kd3 Bb6 35.Ke2
Interesting was 35.e5+!? fxe5?! 36.Ke4, when GV took some convincing that Black was totally lost after 36...Bd4?? 37.Nxd4.
I rejected it because of 35...Ke7, when I could not see how White would make progress and I was worried about putting a white pawn on a dark square. I was also worried that Black would somehow be able to make use of his kingside majority.
Looking at the position now, I feel I was fearing shadows, and so should have played on. Certainly, the engines reckon White is slightly better.
35...Bc5 ½-½
The result means I finished 30th on tiebreak with a score of +5=2-2, plus a one-point default bye, for a rating loss of 5.2 elo. It seems that later today at the prize-giving I should receive 85 euros - exactly the same as the entry fee.

Juniors Sometiimes Get A Taste Of Their Own Medicine

IN round nine of the Benidorm U2000 I faced a 13-year-old boy rated 1625.
That may not sound too terrifying, but 1625 was his rating at the start of the tournament - his December elo, which is not in effect as the tournament began on November 30, is 1740.
On top of that, he had gained more than 160 elo from the first eight rounds of the tournament, so his live rating by the time he met me was over 1900.
Fortunately, I knew all this before the game began, so there was no chance of me taking him too lightly.
Miguel Ruiz Buenida (1625) - Spanton (1940)
French Winawer Exchange
1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.exd5 exd5 5.Bd3 Nc6 6.Ne2 Bg4!?
Alekhine played this as long ago as 1911. But in 1927, in the first game of his world championship match against Capablanca, he preferred 6...Nge7, which is overwhelmingly more popular today.
7.f3 Bh5 8.0-0 Nge7 9.a3 Ba5 10.Re1
My main analysis engines Stockfish9 and Komodo9 prefer 10.Na4.
10...0-0 11.Be3
This seems to be a new move, but is Stockfish9's choice.
11...Qd7 12.Ng3
On 12.Nf4 Bg6 13.Nxg6 I was planning 13...fxg6!?
12...Bg6 13.Re2 Rfe8 14.Bxg6 Nxg6
I felt ...fxg6 was less appropriate here as I had hopes of getting the knight to the f4 square, but it was certainly playable.
15.Qd3
Not just developing the queen, but preventing the sequence 15...Bxc3 16.bxc3 Na5 and 17...Nc4.
15...Re6 16.Rae1 Rae8

So far, fairly humdrum - but RB now came up with the type of move that juniors are used to exploiting rather than committing

17.Bd2? Nxd4
Black has won a pawn for free and is clearly much better, but RB now played a highly imaginative, but extremely bad, move that I had not even remotely considered.
18.Nxd5??
I recovered from this surprise sufficiently to find one of several refutations, namely:
18...Nxe2+ 19.Rxe2 Bb6+ 0-1 (34 moves)
My reward for this: 2.8 elo.

Black To Play And Win?

FACED my second Belgian of the tournament in round eight of the Benidorm U2000.
I won a pawn in the opening, but had to make some kingside concessions.
Later, Black had the chance to go for a combination, but is it sound?

White has just played 26.Ne5-d3 in Spanton (1940) - Dirk Voet (1820)

*****
*****
*****
*****
*****
*****
The combination is 26...Bxc3?? 27.bxc3 Nxc3, but it is definitely unsound as White has 28.Qd2, eg 28...Nxd1 29.Qxg5+ Kh7 30.Ne5, when Black faces ruinous loss of material.
The game saw 26...Rhe8 27.Bb3 a5 28.Bd4!
Inviting an isolani on d4, but in return for a great outpost on e5.
28...Bxd4+ 29.cxd4 Qc6?! 30.Ne5 1-0 (35 moves)

Throwing Away A Win

BENIDORM U2000, along with its sister tournament, which is for players rated under 2301, is unusual in that it consists of 10 rounds over nine days (some years, but not very often, it is 10 rounds over 10 days).
Each round starts at 4.30pm, except for the double-round day when the morning game begins at 10am.
Yesterday saw this year's double-round day, but my morning opponent did not turn up (an all-too-frequent occurrence in Spanish tournaments in my experience), so I had to sit around twiddling my thumbs for an hour in case he showed.
In the afternoon/evening round, I reached the following position against an 11-year-old boy.

White to make his 40th move in Spanton (1940) - Pablo Fuertes Cirauqui (1807)

*****
*****
*****
*****
*****
*****
40.e6??
White's advantage is overwhelming, but this is not the way to convert it.
If I had been taking my time, I would have seen the danger to my king from a check on h6.
Stockfish9 reckons it is mate in 29(!) moves starting with 40.g4. In any event, I needed to give my king more air.
40...Bh6+ 41.Ke5 Re3+ 42.Kd4 Rxe6 43.Qd8+ Bf8
I could see no way to make progress and so felt obliged to accept my opponent's draw offer (made in my time, naturally).

Worst Game Ever?

ROUND five at the Benidorm U2000 saw me play one of my worst ever games.
I quickly got a huge advantage out of the opening, mainly thanks to prep. Indeed, Stockfish9 reckons I had a winning advantage as early as move 10, but I gradually lost the thread.

My last chance came after White had made his 30th move in Jaime Esquerdo Nogueroles (1781) - Spanton (1940)

Oblivious to White's main threat, I saved the exchange by counterattacking with 30...Re3??
There followed 31.Qh2, which wins on the spot. I played on for a few moves by sacing my queen for totally inadequate compensation, but a stronger player might well have resigned.
Instead I had the simple 30...Bf7, which also saves the exchange while leaving Black able to protect h6. Black is then slightly better thanks to White's out-of-play queen's rook.
Note that the tricky 31.Rxh6!? works brilliantly against 31...Kxh6?? as White has 32.Qh2+ Kg7 33.Qh7#. But Black is better after 31...Rh8 as White is still hampered by his offside queen's rook.

Queen's Gambit Inclined

THE Exchange Variation of the Queen's Gambit Declined tends to give White a long-lasting plus-over-equals.
It used to be very popular at the top level, but has fallen out of favour among most of the best grandmasters as it is thought a competent Black should be able to eke out a draw.
Different considerations apply in tournaments such as Benidorm U2000.
Spanton (1940) - Ramiro Rueda Maria (1791), round four
Queen's Gambit Declined, Exchange Variation
1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.cxd5 exd5 5.Bg5 Nbd7
This sets a little trap (6.Nxd5?? Nxd5 7.Bxd8 Bb4+) that has ensnared more than 500 players in ChessBase's 2019 Mega database, but is generally a harmless transposition.
6.e3 Be7 7.Bd3 0-0 8.Nf3 Re8 9.Qc2 c6 10.0-0 h6 11.Bh4 Ne4 12.Bxe7 Qxe7

This tabiya occurs more than a thousand times in Mega '19

13.Nd2!?
There are more than 110 examples of this move in Mega '19, but more popular are 13.Rab1, 13.Bxe4, 13.b4!? and 13.Rae1.
The surprising move among those, at first glance, is 13.b4!?, but the point is that 13...Qxb4 can be met by 14.Nxe4 (14.Bxe4 is also possible) dxe4 15.Bxe4.
13...f5
Major alternatives are 13...Ndf6 and 13...Nxd2.
14.Rae1
Proceeding with a standard Minority Attack seemed unwise with a black knight ensconced on e4. At the same time, I did not want to capture on e4 and give Black even more kingside space.
14...Qg5?!
This has been played by a 2365, but it seems to leave Black on the back foot. The analysis engines Stockfish9 and Komodo9 prefer 14...Ndf6, 14...Nb6 or 14...Nxf2.
15.f3!?
Peter Dittmar (2352) - Wolfgang Gerstner (2365),  Bundesliga 1999, saw 15.f4 Qf6 16.Nf3 Nb6 17.Ne5, with a position where the engines much prefer White (although, according to the database, Black eventually won on time).
The engines like 15.Bxe4 fxe4 16.f3 exf3 17.Nxf3, with an initiative.
15...Nxc3 16.f4!
A similar idea to the Dittmar - Gerstner game, but without leaving a black piece on e4.
16...Qf6 17.bxc3 Nf8 18.Nf3 Be6 19.Ne5 Nd7

White has much-the-better minor pieces

There now follows a long series of moves in which I am able to combine pressure against b7 with pressure against Black's kingside.
20.Rb1 Rab8 21.Rb2 g6 22.Rfb1 Nxe5 23.fxe5 Qe7 24.g4
This could be regarded as double-edged in that both kings become somewhat exposed, but I felt White had more manoeuvring room in which to exploit the situation.
24...Rf8 25.gxf5 gxf5 26.Kh1 Kh7 27.Rg1 Rg8 28.Rbb1 Rxg1+ 29.Rxg1 Rg8 30.Rf1
Avoiding more simplification, while trying to reduce Black to passively defending the f5 pawn.
30...Rg5!?
The engines prefer this to the entirely passive 30...Rf8.
31.Qf2 Qg6
The engines suggest 31...Qe7, but reckon White keeps the upper hand.
32.h4 Rg3?
Afterwards - and during the game, actually - RM was angry with himself at not having played the move he intended, ie 32...Rg4, the point being that trying to win the exchange with 33.Be2?? loses to 33...Rg3, eg 34.Kh2 f4 etc.
But White instead plays the immediate 33.Kh2, eg 33...Qh5 34.Bxf5+ Qxf5 35.Qxf5+ Bxf5 36.Rxf5, with a much-superior rook-and-pawn ending, although the game goes on.
33.Kh2 Rg4 34.Be2 f4 35.exf4 1-0

Catastrophe In The Opening

LOST badly today to a junior in round three of the Benidorm U2000.
Alejandro Garcia Oviedo (1811) - Spanton (1940)
Giuoco Piano
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.c3 Nf6 5.d4 exd4 6.e5
This is much less popular than 6.cxd4, but it scores better in ChessBase's 2019 Mega database.
6...d5 7.Bb5 Ne4 8.cxd4 Bb6
This has been recommended by grandmaster Victor Bologan.
Almost as popular, but not scoring so well, is 8...Bb4+.
9.Nc3 0-0 10.h3!?
The main move is 10.Be3.
The text is a minor sideline that has grown in popularity in the last two years and scores very well for White.
Note that 10.Nxe4? is bad because the d4 pawn cannot be saved after 10...dxe4.

Position after White's little-played but worth-investigating 10.h3!?

10...f6
I took a long look at 10...Nxd4? 11.Nxd4 Nxf2 12.Kxf2 Qh4+ but gave it up because of 13.Ke3? But Stockfish9 points out 13...Bxd4+ 14.Qxd4 Qg3+ 15.Kd2 Qg2+ with a very murky position.
However, the engine improves in a big way by giving back one of the knights with 13.Kf3!, when 13...Qxd4 allows White to exchange queens, while 13...Bxd4?? loses to 14.g3.
11.0-0 Nxc3?
I rejected the obvious 11...fxe5 because of 12.Nxe4? (White should play 12.Bxc6, with equal chances) dxe4 13.Ng5, but 13...Qe7 is simple and good.
12.bxc3 fxe5 13.Bxc6! bxc6 14.Nxe5

Black has the bishop-pair but has to act urgently to prevent being much worse

Black's bishops provide decent compensation for his inferior queenside pawn-structure.
But White has kingside attacking chances thanks to his kingside pawn-majority and the magnificent knight at e5. Meanwhile, Black's dark-square bishop is in danger of being completely shut out of the action.
14...Qf6?
Playing for an attack on f2 that White is easily able to nip in the bud.
I rejected the superior 14...c5 because of 15.Ba3, missing that 15...Re8 indirectly saves the c5 pawn by targeting the knight. Even so, White is still significantly better.
15.Ba3 Re8 16.f4
White duly got his kingside attack and won rather easily in 30 moves.

Blunder!

MY Benidorm U2000 round-two game had an abrupt finish.

I have manoeuvred my king from g1 to a2 and am about to snaffle Black's passed pawn.
However, Black seems to be more-or-less OK after the counterattacking 42...Bg6, although his d5 pawn would remain a target.
42...Qf5??
This looks aggressive, but ignores the fact there are still mating threats when queens remain on the board.
43.Qf8+ Bg8 44.Be6 1-0

Black To Play And Win

AM one of just over 350 entries in the U2000 tournament at the Gran Hotel Bali in Benidorm on Spain's Costa Blanca.
In round one I reached a position in which Black has only one winning move.
There is nothing particularly surprising in that but, in postmorteming the game with two friends I was surprised neither could find the winning move despite trying just about every legal move in the position!

Black is a pawn up, but the h7 pawn is very vulnerable to White's king.
A move such as 49...Ke5 is easily parried by 50.Rd7, while 49...f5 50.gxf5 gxf5 is not much help as now all Black's pawns are vulnerable.
The solution is:
49...h5
I do not give this an exclamation mark, although it would get one under the John Nunn endgame convention, as I think the move is, or at least should be, fairly easy to find (assuming you already know the idea).
50.gxh5
50.Kf4, as suggested by one friend, is no improvement after 50...Rh3, eg 51.Kg5 Rg3 etc.
50...Re5+ 51.Kg4 Rxh5 (0-1, 56 moves)
