Ashtead give Kingston 1 a fight (and a fright)

Ashtead 1 v Kingston 1, Surrey League division 2 match played at the Peace Memorial Hall, Ashtead on 10 December 2024

A somewhat depleted Kingston team nevertheless outrated newly promoted Ashtead on all boards. We are, however, far too experienced to expect an easy match, and this was confirmed by the early results – there weren’t any, and it became clear that most games were heading for time trouble, where, as we have already seen this season, anything can happen.

On board 5, David Rowson had conceded a space advantage against Ashtead captain Bertie Barlow, who had also played for Richmond against our TVL first team the previous night. He found a good sequence of exchanges to get to a slightly better endgame (queen, rook and bishop each), but the position was blocked and with progress unlikely a draw was agreed.

Alan Scrimgour struck our first blow on board 7. A couple of inaccuracies as White had allowed his opponent Tom Barton to equalise. He prepared a kingside attack which induced his opponent to weaken on that side, pounced on the opportunity to open the h-file for his rooks, and quickly won decisive material.

1–0

Peter Large has been in tremendous form for Kingston, but got no change out of Phil Brooks’ French Defence on board 1. Computer post-mortem analysis found a couple of opportunities to establish a +1 edge, but requiring an indifference to the pawn count which is difficult for human beings. No one can accuse these top players of a grandmasterly draw – the battle ended with bare kings.

The highlight of the match was Peter Lalić’s game on board 2 as Black against Dan Rosen, who is able to play for Ashtead in division 1 this year now that Wimbledon are in division 2. After characteristic early exchanges, Peter had the advantage in the early endgame based on White’s doubled e-pawns. In trying to defend those, the white rook became trapped in a box on the queenside, only able to extricate itself by means of an exchange which ruined his queenside structure. Despite getting down to a minute on his clock, Peter was able to set up a prolonged zugzwang, starting on move 36.

White is in zugzwang. The king cannot move without losing the front e-pawn, which also allows the black knight into the white position. The knight on b1 cannot move without losing the a-pawn. c3 would allow Kb3. White can move his g- and h- pawns, but Black can soon block those without breaking the zugzwang.

Zugzwang again. c3 allows the black king in to win that pawn, and moves by the knight and king concede a pawn immediately.
43.Ke2Nxe444.Kf3f5And a pawn down while still tied down, White resigned. Black can exchange knights and win the king and pawn ending.0–1

On board 6, Ian McLeod accepted my offer to go into an unbalanced middle game, in which he gave up bishop for knight to double my f-pawns.

12345678abcdefgh

My judgement was that the resulting big centre and two bishops would outweigh the doubled pawns and the difficulty in finding a safe place to put my king. The final position illustrates the success of that strategy, with White immobilised by the black pawn rush.

12345678abcdefgh

By now White was almost on the increment and struggling to find sensible moves to play. Material is still level, but the e3 pawn is about to fall, and after Black plays e5 white will be almost paralysed. So White resigned. I had had some amusement in the game from making my first move with my king’s bishop on move 25. But this was misleading, as the bishop had protected several important squares from its initial position and had retained the choice of diagonal on which to emerge until the last minute. Motionless but not inactive.

That took us to four points, with three games still in play. Unfortunately, Jasper Tambini had drawn a short straw on board 4. As an overseas newcomer, James Allison’s estimated ECF rating is derived from his Fide rating, and (to judge from the usual difference between Fide and ECF) is at least 150 points too low. For a long time the post-mortem computer evaluation was that White had little more than his starting edge, but Jasper found his activity limited against white’s Catalan structure, tried a sacrificial approach to break out, and conceded defeat a rook down when it became clear that black’s counterplay had been thwarted.

Peter Hasson’s game against Jonathan Hinton on board 3 had so much in it that it would justify its own blog, and we are grateful to him for reconstructing it despite having stopped recording well before the end of the game. Peter had White and opening subtleties had given him a big advantage by move 23, when he missed a lovely combination.

12345678abcdefgh
Here, Peter plays what the engine considers the strongest move, but the move he wanted to play but couldn’t compute to the end of the analysis was 23. Qh1. Everything is winning, but winning in such divergent ways – decapitate the queen or just win material to get to a winning endgame – that the head spins. The variations give some idea of the complexity. The key in the line Peter chooses is to bring the knight into play, and the clue to White’s advantage is of course those three sleeping Black pieces, still at home so deep into the game.

23.Qh1The move Peter would like to have played. He had calculated23…gxf324.Rh8Qg625.Rxc8“I got this far he says, but missed the decisive 26.Rg8+ if Black plays 25.

Black does not of course have to accept the sac. The engine recommends 23…Be6, but this is also hopeless23…Qg6Not23…Nxc6though this line is by no means easy to calculate24.Nd5Qg625.Qh1Ne526.Ne7Bb727.Qh4Nf328.Nxf5+Qxf529.Qe7+Qf730.Rh7+Kxh731.Qxf7+24.Qh1Now Peter has the position he wanted and it should indeed be winning if White introduces his knight into the fray, but he opts to exchange instead24…Nxc625.Qxc6?
12345678abcdefgh
Peter is playing for an endgame in which he calculates Black’s light-squared bishop will be a liability. But, rather than swapping his active rook for Black’s immobilised one, he should continue with the attack by activating his knight in a line whose themes are the same as the one shown in the previous variation

Peter has the “winning” endgame he was seeking, but with time ticking down Black retains drawing chances, as we will see

“Black’s best chance,” says Peter. “Although it shouldn’t work, it does change the nature of the game and White immediately goes wrong.”

12345678abcdefgh
“A mistake,” says Peter, “as the pawn is blocking the bishop on b3 from stopping the f-pawn. It is this pawn, rather than the material, that has the potential to end the game. The bishop is transformed from a problem piece into one which is superior to the knight. White had various winning moves.
54.Nc8is the most thematic as the knight’s greater manoeuvrability is used to drive through the extra pawn”54…Ke455.Kc5Bc256.Ne7Ba457.f5Be858.f6Bh559.Nxd5Kf560.Kd6Bf761.Ke7Bxd562.f7Bxf763.Kxf7Ke464.d5Kxd565.Kf6Kd666.Kf5Ke767.Kxg4Kf668.Kh5Kf569.g4+Kf670.Kh6Kf771.g5Kg872.Kg6Kh873.Kf7Kh774.g6+Kh875.g7+Kh776.g8=Q+Kh677.Qg6#

There are many other variations, but this shows the key themes. Black will eventually get a pawn home. Unfortunately by this stage Peter only had a minute left on his clock. Those of us who had been scarred by Will Taylor’s loss on time against Guildford 2 the previous week would cheerfully have taken the bird in the hand (the draw necessary to win the match) while Peter pursued the full point in the bush. One spectator thought that as Black was down to king + bishop by the end, that was insufficient mating material so we were assured of a draw even if White’s (metaphorical) flag fell. Others thought that because a legal sequence of moves leading to mate could be constructed, we were still at risk unless and until Peter lost all his material. With enviable calmness, Peter pursued the win, with the clock ticking below 20 seconds at one point. But after missing that subtle chance on move 54 – would you spot Nc8 playing to all intents and purposes on the increment? – there was no way through.

By the end. Peter was justifiably frustrated, while the rest of us were relieved. Either way, though, a memorable game with very instructive lessons, and thanks again to Peter for reliving it. Let us hope it is cathartic.
½–½

Last to finish was John Bussmann on board 8. John had built an advantage in the middle game, won a pawn, and then sacrificed the exchange for a second pawn to maintain the initiative. Strictly the sacrifice was not necessary, but he rebuilt his advantage after it. In the position below, he had a clear win.

There were a great many moves after this, but in the time scramble Black lost the compensation for the exchange and ultimately lost the game.
1–0

So in the end we scraped home by the minimum margin. Well done Ashtead for outperforming their ratings; let’s hope they can repeat that fighting spirit in their other home games and nick some points off other teams, which would help us in the title race. Thanks to the Kingston players for making the journey, especially Peter Hasson, whose trip home to Farnham was delayed by a road closure, completing what for poor Peter (one of our four Peters!) was a very frustrating evening.
