Noses in Front

Aberystwyth keeps finding ways to preserve our unbeaten record in the U1800 section of Welsh Chess Union Online League, On Tuesday 24th November we were outgraded on all boards but still managed a favourable result. The exchange variation of the French Defence is not as drawish as its reputation, at least at club level, and I was never quite comfortable with the open position in my game against Adrian Davies. However, he allowed things to resolve into equality and an early draw. James Cook played more agressively on the White side of another Exchange French attacking on Les Philpin's queenside. In an equal queenless middlegame with enough complexity to keep things interesting, James was able to exploit his opponent's back rank for the win. Tom Gunn played too passively against Huw Jones's Torre System, missing chances to break in the centre, and the white squares around his king became fatally weak, as White invaded to clinch the win. Sam Holman's game against Luke Williams began as a Najdorf Sicilian, but reached a middlegame typical of the Dragon, with players castled on opposite sides and a lot of complications. Sam emerged with an extra pawn and was able to create a winning passed pawn in the ending. After our 2½-1½ victory, and with our closest rivals, North Cardiff Panthers, drawing again, Aber is now in the sole lead with one round to play.
