With the return of over-the-board chess still looking a distant prospect, the Welsh Chess Union has organized a new online contest, the WCU Online League. Aberystwyth has entered the Under 1800 section of this, with Rudy van Kemenade, who is too strong to play in this section, as non-playing captain. Matches are played on Lichess, with four-player teams and a rather faster time-limit than we were used to in the Dyfed League. Results do not count towards national grading.
On Tuesday 15th September, we played our first match, against North Cardiff Titans. I had White on Board 1 against Liam Penny, in the Portugese Variation of the Scandinavian Defence (one of those delightful hybrid names that chess occasionally comes up with). Black weakened his kingside position but was holding well, and a pawn up, till I found a tactic that regained the material with advantage. Passing up an opportunity for a kinghunt, I transposed into a favourable rook ending, and was able to win it without too much trouble. On Board 2, Julie van Kemenade played a Philidor-type opening with an early queen sortie that she has been using recently - I'm not sure if it has a name, but it seems active and interesting. The position was level till she missed a trick that cost her a pawn, which seemed to discourage her, though she was still reasonably well placed. White took the initiative and invaded on the seventh rank, winning material and the game. On Boards 3 and 4, Tom Gunn and Sam Holman were playing much lower-rated opponents, Callum Penny and Kushi Bagga. Both the Aber players had White, because of a technical issue which meant the Board 4 game was played with reversed colours. The two games, a Colle System and a Ruy Lopez, Bird's Variation, followed a similar course, with the Cardiff players attacking prematurely and giving up material without compensation, allowing their opponents to launch mating attacks with their extra firepower. Our first online match was a 3-1 win to Aberystwyth.
