Overview

King's Gambit Declined: Petrov's Defense is a sacrificial opening line filed under ECO C30 in the Open Games group. The defining idea is the early concession of material to seize the initiative and unbalance the position.

The Open Games group covers open games — classical 1.e4 e5 openings where both sides contest the centre directly with pawns.

It begins with 4 plies and takes 1. e4 e5 2. f4 Nf6 to reach the canonical position.

In the opening tree, this line branches off from King's Gambit, part of the broader King's Pawn Game system.

Use the board to walk through every move, check how the position has scored on Lichess, or take it head-to-head against Stockfish.
