The Cardigan Season

There is a time in almost every chess season when one or other of the Aber teams seem to be playing Cardigan almost constantly (though, to be fair, this was truer in the days when Cardigan also fielded two teams). That time has now arrived, and on Tuesday 28 February, it was the B team's turn to host the League Champions, the first time we have played them at our new venue of the Brynamlwg Tavern. On top board, Adam Robinson could never quite match Howard Williams's piece activity in a constantly changing ending, and by the time it got down to opposite-coloured bishops the two-pawn deficit was enough to ensure his defeat. Julie van Kemenade, in her first match for some time, played an ingenious exchange sac against Iolo Jones, whose defence was ingenious enough to cope with it. Julie might have had a draw, but lost while trying for more. My game against Tony Haigh was a French Exchange that never looked like being other than a draw, a complete contrast to the game on Board 4, where James Corrigan played the wild Danish Gambit against Awne Osinga, and eventually got the attack he was seeking, winning a piece with more material to follow. The result was 2½-1½ to Cardigan.
