One of the most irritating defences to meet when playing 1 d4 as White is the Benko Gambit (1 d4 Nf6 2 c4 c5 3 d5 b5). It was foreshadowed by a Ruy Lopez between Nimzowitsch and Capablanca from St Petersburg 1914. In that classic game, White won a queenside pawn in ingenious fashion, only to see the black forces pour down the open lines occasioned by the pawn loss and destroy White’s queen’s flank.
