Aberystwyth continued its good start to the season on against Steynton C on Monday 22 October at the Emlyn Cafe, Tanygroes. It is never a good idea to hang a piece against Rudy van Kemenade, as Colin Denham did on top board for Steynton in a Dutch Defence. Rudy temporarily gave back the piece but soon crashed through on the kingside. Another dubious strategy is to castle queenside in a Sicilian. Julie van Kemenade, playing White against Gwyn Evans had no trouble switching her attack to the other wing, weakened by the advance of the c-pawn, for a decisive victory. James Cook, back in the team after a longish break, played his trademark Caro-Kann, and used the key white-squared bishop to break up Ray Greenwood's kingside for a winning attack. Ian Finlay dominated the centre in a Tarrasch Queen's Gambit against Margaret Baron, and a series of tactical errors by Black left the result in no doubt. Aberystwyth's first clean sweep of the season, 4-0.
