Order Restored

Rudy has now had a chance to analyse the match between the A and B teams played at Brynamlwg on Tuesday 24 January, so order is restored in this blog. On top board for the A team, Robbie Wright was always ahead after Ian Finlay's miscalculation in a Sicilian Defence cost him a piece, and the end was not long coming. Adam Robinson had a complex struggle in a Modern Defence against Sam Holman, but emerged ahead after a series of exchanges and was able to push a passed pawn for the win. I caught Conor McEwan in an opening trap in the London System that I was familiar with from the internet, winning quickly. James Corrigan couldn't make headway against Kieran Judge's unusual but sound anti-Sicilian line; he might have had a significant endgame advantage at the moment he agreed a draw, but the result was a fair reward for Kieran's strong performance against a much higher-rated player. The A team won the match 3½-½.
