Opening Time

Aberystwyth maintained their good form of the season at home to Gwyddbwyll.com on Tuesday 17th April with a comfortable win, dominating all the games from the early stages. Playing White on top board, Adam Watkin-Jones took advantage of Iwan Griffiths's unfamiliarity with the theory of the Semi-Tarrasch Defence, gaining a passed pawn and a big space advantage, which he soon transformed into the win of a piece. I was nervous against Tegwyn Jones after a bad run of form recently, but quickly picked up two pawns in a Budapest Gambit, and was able to exchange into a winning ending without too much difficulty. Sam Holman's no-nonsense approach to the tricky Bird's Defence to the Ruy Lopez was not the best, but Dylan Jones didn't know the theory either and got a cramped position, allowing White to build pressure against a pinned knight and eventually win it. Dan Hardman's game against Emyr Llywelyn was a quiet Reti where White's aimless manoeuvring let him in for a knight fork, after which he was always ahead. A 4-0 win for Aberystwyth keeps the club on course for this year's League title.
