Theory Wars

Aberystwyth fielded a strong B team against the formidable Dyfed League champions Cardigan at the Emlyn Cafe, Tanygroes, on Wednesday 15th February. Playing White on top board, Robbie Wright took on Howard Williams in a sharp theoretical line of the Sicilian, a calculated risk that unfortunately ended in an early mate by Black. Adam Robinson, too, chose a very theoretical opening against Iolo Jones, but his King's Indian led to a blocked game rather than the usual fireworks. Iolo uncharacteristically missed a win in the manoeuvring, and eventually had to settle for a draw. Against Tony Haigh, I found myself facing a line of the Leningrad Dutch that I played myself in a match a few years ago. I couldn't remember the theory, but got as far as move 14 before misplaying it and getting an awful position, from which there was no escape. On Board 4, Conor McEwan's Steinitz Defence against Howard Leah's Ruy Lopez produced a cramped but playable position. Black got a bit of counterplay as White charged down the kingside with his pawns, but it wasn't enough. The match ended 3½-½ to Cardigan.
