Overview

Bishop's Opening: Lewis Countergambit, Walker Variation is a gambit, classified under ECO code C23 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.

It begins with 9 plies and takes 1. e4 e5 2. Bc4 Bc5 3. c3 d5 4. Bxd5 Nf6 5. d4 to reach the canonical position.

It is a variation of Bishop's Opening: Lewis Countergambit, which itself descends from the root opening King's Pawn Game.
