A Hardman is Good to Find

Steynton B could only field three players against Aberystwyth at the Emlyn Cafe, Tanygroes on Wednesday 11 April, meaning that we needed one and a points to seal the match. On top board, Rudy van Kemenade won a pawn early on against John Miller in a King's Indian and had a dominating position throughout, picking up more material as Black looked vainly for counterplay. I got good pressure in a Sicilian against David Pinch's King's Indian Attack setup, but missed a tactic which won him a pawn. I should still have been OK, but was thrown off my stride by my mistake and blundered to bring the game to a quick conclusion. Dan Hardman, playing his first game for the Club, got a dangerous passed pawn against Gwyn Evans's Sicilian, and Black's attempt at a kingside counterattack only blundered a piece, a good start for the new player against a higher rated opponent. Aberystwyth won the match 3-1 with the default on Board 4.

Drawing Ahead

At last, with the Dyfed League season approaching its climax, Aberystwyth's run of wins is over. We are not complaining, though, as a draw with Cardigan A after our win over them in the first leg only consolidates our lead. Here is team captain Rudy's summary of the match, which was played at Brynamlwg on 20 March.

Having managed a last-minute defeat of Cardigan in the first leg of the League, the Aberystwyth team strategy was keep the draw in hand on all boards, and push for more if possible. On Board 1, Brendan tried to keep very active by opening things up. This led to an unbalanced position, whuch Howard Williams could have won - a blunder that might have been a Black win was missed, then, despite engines being clear about a win for Cardigan, time pressure produced a repetition. On Board 2, preparation gave Rudy the chance to gain a persistent pressure to give Iolo a taste of what he does to others, but not enough to gain more than the desired draw. On Board 3, Adam got a promising position against Tony, but it petered out to a draw. Julie got a good position against Howard Leah and Black should have barricaded earlier. As it was there could have been a White breakthrough, but then it settled to equality. Result, Aberystwyth got its four draws
