Online Friendlies

As part of the continuing preparations for the return of the Dyfed League in January, members of Aberystwyth Town Chess Club too part in some individual online friendly matches against similarly rated players from other clubs on Wednesday 30 November. In the strongest match-up, Murray Smith conjured up a strong attack against Lluis Navarro in the usually quiet Exchange Variation of the Caro-Kann. In a high-quality encounter, White's pressure eventually led to the gain of a pawn and a winning ending. Peter Windows walked into a fierce attack from Mark Paffard with his English Opening. Black's imaginative play culminated anticlimactically in a missed mate, and Peter was able to force a draw an exchange down. Against a player only identified as Josh, I sprung a familiar trap with my Vienna Gambit, and was relieved when he not only fell into it, but missed my error that could have let him right back into the game, after which the win was comfortable. Sam Holman got a strong position with advanced passed pawns against Filip Zurek, in a Sicilian Defence, but blundered a rook. Samuel Raybone was another player who fell into an opening trap, in a Caro-Kann against Ewan Ferguson; it didn't lose material as White only regained a gambited pawn, but Samuel lost the right to castle and the defence of his position ultimately proved too difficult. Mixed fortunes for the Club, and bad luck for Luis Sanchez and Tom Gunn, whose opponents didn't show up.

Return Match

The second of our pair of friendly matches against the University team was played in the Hugh Owen Building of the University on Thursday 24th November. Playing his first match for the Club, Luis Ortiz Sanchez had Black on top board againt his compatriot Lluis Navarro. Appropriately the opening was a Catalan, though I suppose a Spanish would have been still more so. White took advantage Black's loose queenside to penetrate the position and was soon able to work his way over to the kingside and force mate. In another Catalan (by transposition from the English), Peter Windows won a piece in the opening and was always winning but had to be patient in the face of some awkward Black counterplay before it finally fizzeld out. Sam Holman's King's Indian soon became blocked; Harry Fox's position looked better, but he had no way through. Samuel Raybone reached a level ending against Patrick Bourne in a Queen's Gambit Declined. Black dropped a pawn and White missed a chance of a winning advantage but the eventual ending with rook and pawn against rook was a clear draw. Once again the result was a friendly 2-2.

Back in Business

The last couple of years have been difficult for chess in the area. Not only were we forced to move to online competitions because of the Covid pandemic, but three popular players and energetic supporters of Dyfed chess have sadly died: FM Iolo Jones, organizer of the Dyfed League and one of the pioneers of modern Welsh chess, Tony Haigh, Treasurer of the Dyfed Chess Association, and David Pinch, who kept chess going by organizing online matches and torunaments when over-the-board play was impossible. They are all much missed.

For Aberystwyth Town Chess Club, the problems were compounded by factors which had been apparent even before the pandemic, the erosion of our membership and the lack of a suitable place to meet. Two valued members, Rudy and Julie van Kemenade moved away from the area earlier this year, leaving us down to four active players, Adam Watkin-Jones, Tom Gunn, Sam Holman and myself - and, now Adam is unable to play for the time being due to pressure of work. In the circumstances, I thought it would be necessary to dissolve this historic club.

But, unexpectedly, things have begun to revive, both for the club and Dyfed. Several new players have moved into the Aberystwyth area, and at the same time FM Howard Williams, the Secretary of the Dyfed Chess Association, has begun the process of reviving the Dyfed League, which is due to start as a hybrid online / OTB event in January. As we look for a permanent meeting place, the Town club has been generously welcomed by our sister club at the University to their Wednesday afternoon sessions in the Arts Centre bar, and we have celebrated having enough players for a team by organizing some friendly matches.

The first of these was played between the University and the Town at the Arts Centre bar on Thursday 17 November. On top board for the Town, Peter Windows couldn't make progress with his kingside attack against Toby Carter's Pirc, and a misjudged exchange left him down in material, with a lost game. I built a defensive stronghold with my Caro-Kann against Toby Bates, and was eventually able to break out with a winning counterattack. Tom Gunn turned the win of a piece into a speculative queen sacrifice in an irregular Queen's Pawn Game against Harry Fox, and gained a decisive advantage in the ensuing complications. Samuel Rayburn also played a Caro-Kann against Rufaro Chisiwenga but lost a pawn to a neat tactic and was unable to get back into the game. A 2-2 draw seemed an appopriate result for this celebratory friendly.
