Trompowsky Attack

The Trompowsky Attack starts 1. d4 Nf6 2. Bg5. White's bishop comes out on move two and threatens to take the knight and double Black's pawns. It sidesteps the big theory of the Indian defences, and Black has to decide at once how to meet the bishop, usually with 2...Ne4, 2...e6 or 2...d5.
