Alexander Alekhine vs Rubinstein, The Hague, 1921, postage stamp
Following several eccentricities by Black in the Queen's Gambit, white embarks upon an early attack, moving his h-pawn three times, his dark-squared bishop four times and, after Bf6, probably has a winning position. Alekhine analyzes this game in detail (game 61) in his Best Games of Chess.
