St. George Defence

The first known chess game involving the St. George was a simultaneous game between an English amateur J. Baker and the first official World Chess Champion Wilhelm Steinitz on 11 December 1868. The game was won by Baker. The advocates of the opening are generally players willing to sacrifice the centre in order to attack from the flank, and to avoid theory. Michael Basman has been known to play the St. George, as did Tony Miles.
In perhaps its most famous appearance, Miles defeated reigning World Champion Anatoly Karpov in the 1980 European Team Championship in Skara, Sweden. The opening also acquired the name of "Birmingham Defence" at this time, after Miles' hometown.
Boris Spassky also played the St. George Defence, albeit by transposition, in the 22nd game of his 1966 world championship match against World Champion Tigran Petrosian. That game began 1.d4 b5 (the Polish Defence) 2.e4 Bb7 3.f3 a6 (transposing to the St. George). This was an inauspicious outing for the defence, however: Petrosian won, giving him the 12 points needed to retain his title.

Una vittoria ottenuta sul campo dal compianto G.M. inglese, che ha in qualche modo come ispiratore il M.I. Basman...
