More of the Same

Aberystwyth's run of good form is leaving me pushed for new ways to describe it - not that I'm complaining. It was more of the same on Wednesday 21st February when we took on Steynton A at the Emlyn Cafe, Tannygroes. Brendan-Budok Durand-Le Ludec played calmly against Martin Jones's quiet Alapin treatment of the Sicilian, targeting the weak pawns, then sacrificed the exchange in the ending to clear out almost all the White pawns that remained, leaving an easy win. Rather as in his last match game, Rudy van Kemenade stormed through the centre with his pawns against David Pinch's King's Indian (by transposition). This time he was helped by Black's vulnerable king, but the result was the same. Adam Watkin-Jones reached an ending with two bishops versus two knights against John Miller, but it proved to be not enough of an advantage for a win. After some early skirmishing in a Sicilian, Julie van Kemenade reached a materially level major-piece middlegame against Gwyn Evans, but her domination of the e-file and Black's shaky king position soon proved decisive. A win for Aberystwyth by 3½-½.
