Happy Days

Aberystwyth scored an excellent result in WCU Online League on Thursay 11 November, beating the top-ranked team of Pontyfenni. On top board, Rudy van Kemenade played the little-known Schallopp Defence against John Waterfield's King's Gambit (at least, it is little-known by me, and on the evidence of this game looks well worth exploring) and a sharp game was initiated, which ended abruptly when White overlooked Black's threat of mate in one. A great result for the team but disappointing from a neutral point of view as the game could have been fascinating. Adam Watkin-Jones had a spatial advantage in a blocked position against Ian Jones's Philidor by transposition; when Black's king was denuded of pawns White looked to have winning chances, but exchanges brought about a difficult queen ending and Adam settled for the draw in view of the team's favourable position in the match. Julie van Kemenade had a solid and active position with her King's Indian against Alan Keene, with chances for both sides, when White, under time pressure, gave away a piece. Sam Holman's game against Justin Morgans was a typical cut-and-thrus Najdorf Sicilian with the players attacking on opposite wings and both missing opportunities to win before White took control in the queen ending. The match finished as a 3½-½ win to Aber.

Aber's Tom Gunn also had a fine result playing for Steynton against Richard Williams of White Knights. Dominating the board against Black's Old Indian Defence, Tom gradually focused all his pieces on the king to force a mating attack.

Match of the Day

After our defeat in the first round of the Open Section of the WCU Online League, Aberystwyth did much better against Morriston on Thursday 4th November. Rudy van Kemenade's Bird's Opening brought him no middlegame advantage against Peter Bevan, and they arrived at the ending equal. Apparently Black was distracted by the football at this stage, and went wrong, dropping a pawn and accepting an unfavourable exchange that left him with a weak bishop against a strong knight, after which Rudy was able to win comfortably. Adam Watkin-Jones's Pirc against Chris Howells quickly transposed into a King's Indian - I'm not sure whether this was intended or not, but Black's position seemed awkward and he was two pawns down when he resigned, perhaps a bit prematurely, given the opposite-coloured bishops. Against Francisco Marin Marin in a Closed Sicilian, my kingside attack was faster than Black's counter on the queenside and in the centre, and the push of the f-pawn broke open his king's position. My queen's bishop remained on its home square all game. Sam Holman's game against Duncan Williams was another King's Indian, in which Black had a dynamic position and good chances in the early stages. After locking his bishop in, though, he came under pressure, and eventually dropped a rook. A 2-2 draw was a good result for Aber.

In games for other teams, Tom got a good win against Keith Briggs's Slav Defence, exploiting Black's queenside weakness to get a passed pawn, then winning with a nice tactic, while Sam, in another King's-Indian-like opening again had a dynamic position against Gwyn Evans, but after both sides made mistakes in the ending the game was drawn.

Back in Business

Although the club has suspended face-to-face chess for the year, members are continuing to take part in online events. The first round of the Dyfed Closed Online tournament recently took place and it will run until January. The WCU online leagues have also resumed, and we are greatly helped here by the fact that Rudy and Julie van Kemenade are still available to play for us. We are taking part in the formidably strong Open section, with Rudy as our captain and top board. We don't have enough available members to field an under-1800 team as well, so Tom Gunn and Sam Holman, as well as taking their turns in the Open team, will be playing for Steynton at the lower level.

Our first match in the Open was against White Knights. Rudy's Petroff against Bill Hewitt reached an unbalaced middlegame where Black had two pieces for a rook. The advantage was with Rudy, who managed to convert the imbalance to a clear extra knight, only to get it trapped in the endgame. After that he was still a pawn up in the queen ending but could only draw. I spent most of the game trying to shore up the weaknesses in my position against Allan Pleasants's Modern Defence, but was beginning to feel more comfortable as time started to run out for both of us. I then thought I saw an opportunity to go on the attack, but it was an illusion and my position quickly collapsed. Julie took too long getting her counter-attack started against Jason Garcia in a King's Indian Defence. White's centre was very dominant, and, as she tried to mix things up, she walked into a pawn fork and resigned at once. Tom's Queen's Gambit gave Tomasz Miga the two bishops and an imposing phalanx of pawns on the queenside, which ultimately proved impossible to stop. White Knights won the match 3½-½.
