Still on Track

The new unified Aberystwyth team had made the perfect start to the season, with two 4-0 wins, and, with a key match against Cardigan A coming up in December, were anxious to continue their good form against Gwyddbwyll.com at Brynamlwg on Tuesday 11 November. Team captain Rudy van Kemenade was planning to rest himself, but, when Brendan-Budok Durand-Le Leduc hadn't appeared by the start time, he took over the top board role. His opponent was his former chess student Iwan Griffiths, a talented player whose grading, well below Rudy's, probably doesn't reflect his true strength. In a Three Knights' Game, Iwan gave up a piece for the attack, and only regained it when the game was entering an ending. With the material balance restored, White still had the advantage, and went on to clinch a fine win. I was also facing a familiar opponent in Owen Llywelyn; I have had White in every one of our many match games, for some reason, and, before tonight, each had been a Caro-Kann. This time he decided to avoid my preparation, and replied e5, leading to a Vienna Gambit. Things were quiet at first but when I picked up a pawn in front of his king, he lashed out with a counter-combination that proved not to work, leading to a quick win for me. Tony Geraghty's opponent, Dylan Jones, in his first match for the club, was also aggressive, sacrificing a piece in a French Exchange, but there was not enough of an attack to justify his boldness. Finally, the Board 4 Queen's Gambit between Ian Finlay and Tegwyn Jones seemed to have reached an inoffensive position when Tegwyn lost on time, but subsequent analysis showed that he had a chance for a win, which would have led to a drawn match. As it is, Aber's 3-1 win keeps us on track for the time being.
