New Year Honours

Aberystwyth continued its good form in the first match of the New Year, away to Steynton A at the Emlyn Cafe, Tanygroes, on Wednesday 10 January. On top board Brendan-Budok Durand-Le Ludec quickly picked up a piece against Colin Denham's irregular defence to 1.d4, and trapped Black's queen soon afterwards. Rudy van Kemenade's win against David Pinch in a Three Knights Game was longer, but White's doubled pawns gave him a long-term disadvantage, and when Black acquired two passed pawns on the kingside the end soon followed. Julie van Kemenade's game was another irregular one, as John Miller didn't meet her King's Indian Attack with the expected ...d5. In the slow manoeuvring that followed, Black seemed to lose track of his vulnerable pawns, leading to a comfortable win for White. I have been playing the same system against Scott Hammett's Bird's Opening for some time now, with consistently mediocre results, and tonight's game was no exception, quickly fizzling out into another draw. Aberystwyth won the match 3½-½.
