The major surprise in the Battersea 1 v Battersea 2 match earlier this week was the win by our Chair Alan Palmer (156) over our Treasurer Adrian Somerfield (192).
The key point in the game came in the featured position where Adrian played 24 …Bxd4? Then if 25 cxd4 26 Qxd2 Rxd2 27 Rxc1 and Black is winning, but Alan found the critical intermezzo mentioned in the match report 25 b4, which wins.
The full game, with analysis, is given below.
