The Dyfed League is now finished for the season, with Aberystwyth the new champions. The title was already secure when we played our last match of the season, against Carmarthen at the Emlyn Cafe, Tanygroes on Wednesday 16th May. On top board Brendan-Budok Durand-Le Ludec went for broke in a Sicilian against Huw Morcom, launching a kingside attack more reminiscent of a King's Indian. White missed out on a hard-to-see chance to take advantage of the looseness this created in his opponent's own king's position, and instead lost material in the complications. Rudy van Kemenade also attacked on the kingside, with his Bird's Opening, but his advancing pawns were stopped, and David Buttell, unlike his team-mate, found a way into the gaps they had left behind them to force mate. On a night when Aber seemed intent on inflicting the maximum possible violence in the shortest time, Adam Watkin-Jones also attacked on the kingside in a Pirc Defence, and landed the killer blow before Paul Orton had even finished developing. While all this was going on, Julie van Kemenade, usually a fierce attacker herself, had reached a comfortable position against Robert Narayan-Taylor's shaky-looking irregular defence, but, seeing a draw was enough to bring Aberystwyth's season to a successful close, she offered it. A 2½ - 1½ win meant the Club had gone through the whole season undefeated, conceding only one draw, to second-placed Cardigan A.
