What's in a Name?

Carmarthen were lacking their strongest player, Gerry Heap, for the match against Aberystwyth at the Emlyn Cafe, Tanygroes, which meant they were comfortably outgraded on all boards. It's not always easy to cash in on such an advantage, but Aber at this early stage of the season, were in dominant form. On top board, Brendan-Budok Durand-Le Leduc, who has the longest name in the league as well as one of its highest gradings, seemed well prepared against David Buttell's Sicilian Dragon. Black's gambit didn't lead to any real attack, and Brendan was able to dominate with his passed pawns, winning on time when resignation must have been close anyway. Rudy van Kemenade, whose name seems almost humdrum in comparison, built a strong kingside attack against Paul Orton's London System, but didn't need to break in for mate as Black lost a piece to a pin and resigned. Julie van Kemenade dominated the centre with her closed line against Robert Narayan-Taylor's Sicilian in a way more characteristic of the open variations. When Black weakened his king's position with g5, the end came quickly. In the evening's third Sicilian, I picked up a piece early on against Wilf Davis, who was playing his first ever competitive match, and despite White's stubborn resistance, went on to close out the game. A second 4-0 victory in succession for Aberystwyth.
