The St. George Defence (1…a6) is easily underestimated, yet this opening idea has remarkable surprise value and is strangely flexible. The first known chess game with the St. George was a simultaneous blindfold game in 1868 between English amateur J. Baker and World Champion Wilhelm Steinitz, which was won by Baker. More recently, Tony Miles used the St. George to defeat World Champion Anatoly Karpov. Excellent credentials!
