Aberystwyth had another good result in the second round of the Welsh On-line League on Tuesday 29th September when we played De La Beche Rooks. On Board 1 my Stonewall Dutch position was soon invaded by Alan Fisher after I weakened it by exchanging dark-squared bishops. When White missed a mating attack I found myself, much to my surprise, still in the game, but I had used a lot of time and failed to save the draw in the rook ending that followed. James Cook went a pawn down playing the Alapin against Peter Smith's Sicilian, but Black got in a tangle that eventually caused him to drop a piece. The game became very unbalanced as James sought to hold back Black's advancing pawns with his knight, but eventually settled into a draw. Once again, Boards 3 and 4 came up with the goods for Aber. Tom Gunn was in some trouble with his Kan Sicilian against Vaughan Thomas, who had an extra pawn and a better development. But White played too passively, allowing Tom to win back the material and get the upper hand in the ending before eventually winning on time. Sam Holman had arrived at a level middle game position in a Ruy Lopez Steinitz against David Belochkin when his opponent started giving away pieces, after which the win was straightforward. A win to Aber by 2½-½. Our next match will be against the very strong Steynton A team on Tuesday 13th October.
