Noses in Front

Aberystwyth keeps finding ways to preserve our unbeaten record in the U1800 section of Welsh Chess Union Online League, On Tuesday 24th November we were outgraded on all boards but still managed a favourable result. The exchange variation of the French Defence is not as drawish as its reputation, at least at club level, and I was never quite comfortable with the open position in my game against Adrian Davies. However, he allowed things to resolve into equality and an early draw. James Cook played more agressively on the White side of another Exchange French attacking on Les Philpin's queenside. In an equal queenless middlegame with enough complexity to keep things interesting, James was able to exploit his opponent's back rank for the win. Tom Gunn played too passively against Huw Jones's Torre System, missing chances to break in the centre, and the white squares around his king became fatally weak, as White invaded to clinch the win. Sam Holman's game against Luke Williams began as a Najdorf Sicilian, but reached a middlegame typical of the Dragon, with players castled on opposite sides and a lot of complications. Sam emerged with an extra pawn and was able to create a winning passed pawn in the ending. After our 2½-1½ victory, and with our closest rivals, North Cardiff Panthers, drawing again, Aber is now in the sole lead with one round to play.

Counter and Counter-Counter

Following our brave but ultimately unsuccessful struggle against Cardigan in our first match in the new Dyfed Online League, Aberystwyth were looking for our first win against Steynton B on Tuesday 17th November. Adam Watkin-Jones played actively against Paul Orton on the Black side of a Ruy Lopez, and won material, but then White counterattacked and had chances of his own, as both players overlooked the capture of a rook, after which a counter-counter-attack ended things quickly: one of those games, perhaps, where the lower-rated player didn't really expect to win, and lost out as a result. I developed quietly against Jonathan Jones's Scandinavian and had a comfortable position when he tried a speculative pawn sacrifice. There was nothing there for Black in view of White's central control and good development, and he threw away too much material in an attempt to create tactical possibilities. Tom Gunn dominated the board when Keith Briggs played passively in a London system. White's attempt to find kingside counterplay led to nothing, and the capture of his problem bishop ended the game. Sam Holman, playing White in a Ruy Lopez, won the exchange against Gwyn Jones and was better for most of the game, but it's often difficult finishing in such circumstances, and Black belatedly got his two knights working together for a tactical coup. A 3-1 win for Aber, but with some adventures along the way.

Touch Wood!

Touching wood is generally all part of the game as far as chessplayers are concerned, but with competitive chess having moved online I had better make a special effort to touch some when reporting that Aberystwyth is still doing very well in the Under 1800 section of the Welsh Chess Online League In Round 4 on Tuesday 10th November we played the other leading team, North Cardiff Panthers, who were ahead of us on game points but like us had won every match. I thought I saw a quick win against Callum Smith's Pirc, but had to withdraw in confusion when it didn't work out. After that I had a long defence, tied to a weak pawn, but Black weakened his position trying to break through the solid centre and I regrouped for another unlikely win. Julie van Kemenade didn't manage to get her kingside counterplay going against Ellison Smith's queenside pressure in a Giuoco Piano, having to castle kingside not only slowed her down but left her vulnerable there too, and White overran her position. James Cook uncharacteristically sacrificed a piece early on in his Ruy Lopez against Bence Szakmany; it turned out to have been a mouse slip, but he did the right thing by keeping his pieces active, pushing his passed pawns and seeking to confuse matters, till his opponent lost his way in the complications. Sam Holman, heavily outgraded against Alun Smith, played vigorously in on the Black side of an Alapin Sicilian, and had good chances most of the way through a complex game, before the loss of a pawn allowed White to reach a won ending. A 2-2 draw means that we are still undefeated at the top of the League - touch wood!

Another Online League

With the Welsh Chess Online League having made a successful start, Aber is now involved in another such contest, the online version of the Dyfed League. Time limits and rules are the same, as for the national competition. Our first match, on Tuesday 3rd November, was against old rivals Cardigan, who as usual fielded a strong team, though sadly missing Dyfed League Director Iolo Jones, who is ill. On top board Rudy van Kemenade's King's Indian Attack against Howard Williams's Sicilian led to a sharp position with both kings exposed. Howard declined Rudy's pawn sacrifice, wisely as it turned out, and the complications eventually ended in a draw. (This game has now been updated to include Rudy's latest annotations.) My Dutch worked out well against Ben Brewer, whose premature attack left him behind in development, and the game ended abruptly when he missed a tactic that lost him his queen. Julie van Kemenade's Veresov left her position rather congested against R. Gareth Williams, and his minor pieces, two collaborating bishops and a well supported knight, were powerfully posted, leading to a win of material and a decisive attack. Tom Gunn's early retreat of his pinning bishop in a Nimzo-Indian seemed a passive approach, and his position, too, looked cramped, but he maintained equality till quite late in the game, when the weak squares around his king allowed Joshua Brewer to break through with a kingside attack. 2½-1½ is not a bad first result for Aber, considering we were outgraded on every board.
