Overview

King's Pawn Game: La Bourdonnais Gambit is a gambit, classified under ECO code C40 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.

Play reaches this position via 1. e4 e5 2. Nf3 Qf6 3. Bc4 Qg6 4. O-O, after 7 plies of opening development.

It is a variation of King's Pawn Game: McConnell Defense, which itself descends from the root opening King's Pawn Game.
