Alexander Alekhine vs Bogoljubov, 1922, postage stamp, Laos

   One of the greatest games ever played, and well worth study. Beginning with 29.Rxa5, white's rook captures both of black's rooks and black's queen, but is foiled by a single, unstoppable pawn. Perhaps the most amazing shock is 34...Ne1 threatening an original smothered checkmate on f3!
