Petrov's Defense: Cochrane Gambit, Bishop Check Line
Overview
Petrov's Defense: Cochrane Gambit, Bishop Check Line is a gambit, classified under ECO code C42 within the Open Games family. As with all gambits, one side sacrifices material early — usually a pawn — in exchange for development, open lines, or initiative.
The Open Games group covers open games — classical 1.e4 e5 openings where both sides contest the centre directly with pawns.
It begins with 9 plies and takes 1. e4 e5 2. Nf3 Nf6 3. Nxe5 d6 4. Nxf7 Kxf7 5. Bc4+ to reach the canonical position.
It is a variation of Petrov's Defense: Cochrane Gambit, which itself descends from the root opening King's Pawn Game.
