Out of Order

The title doesn't refer to the state of this blog, for once, but to the fact that I still haven't covered the match between A and B teams, which took place at Brynamlwg on Tuesday 24 January and resulted in a 3½-½ win to Aber A. The scores were put in the Club chest, and Rudy hasn't yet retrieved them for analysis, so meanwhile here is the report on the match between Aber A and Steynton A, played at Tanygroes on Wednesday 8 February.

On top board Rudy van Kemenade, playing Black in a Petroff, showed the patience necessary for a strong player, persisting in trying for a win in an ending where his advantage was slight. Eventually Martin Jones made the mistake that allowed him through. Robbie Wright took advantage of Gwyn Evans's inaccuracies, winning not so much through his typical White kingside attack in the Sicilian as the material his opponent let slip in defending it. I tried to play positionally against Scott Hammett's Bird's Opening, having the better bishop for most of the game, but my attempted breakthrough was a disastrous mistake. Luckily for me he missed the win, and I was able to force a draw in the ensuing queen ending. James Corrigan's game against Robbie Coles was another Sicilian, this time through a French move order. James's clever knight sacrifice, even though declined, opened the Black defences for a convincing win. Aber A won the match 3½-½.

If you are not yet entered for the Dyfed Congress, due to be played in the delightful setting of the Fishguard Bay Hotel on the weekend of 24-26 February, there is an entry form here. It's always a highlight of the chess calendar in Wales.
