Penrose ( born 1933) is a grandmaster both ICCF and FIDE. An academic psychologist by profession, he holds the record for winning the greatest number of British OTB championships(ten). He took up postal play in the mid-1970s,winning several muster tournaments. Dr. Penrose retired from CC soon after coming third in the 13 WC. My win over Jonathan Penrose was to a cosiderable degree already predetermined in the opening. My opponent, in a known theorethical variation, used a novelty instead of continnuation which promised equal play. Possibly, by employing the novelty, he hoped to obtain an advantage, but after a few preceise moves by White, Black found himself in a worse position. White prepared and carried out a breakthrough in the centre which led to destruction of the black king's pawn protection and to a direct attack.
