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.
