King's Gambit Declined: Petrov's Defense with 3.Nc3
The King's Gambit is one of the most aggressive openings in chess, but Black doesn't have to accept the pawn. With 1.e4 e5 2.f4 Nf6 3.Nc3 d5, you instantly strike in the centre and challenge White's setup. You're playing Black in this position, and the numbers are clear: this is a fighting, balanced line. Across over half a million games on Lichess, Black wins 48.6% and White wins 48.1% — about as close as it gets. The engine agrees: Stockfish evaluates the position at -0.24, a tiny edge for Black. That means you are slightly better from the start. Below, you'll find everything you need to handle White's most popular replies and punish their common mistakes.

The most common move here by a huge margin is fxe5, played in 437,850 of the 553,751 games in the database. White takes the gambit pawn and scores 48.6% — which means you still score over half the points as Black. The engine's top choice is also fxe5, and the best continuation runs fxe5 Nxe4 Nf3 Bc5. After you recapture with 3...d5, your knight on e4 is active and your bishop goes to c5, putting pressure on White's kingside and centre. Your lead in development and central control offset the missing pawn. White has to be careful not to let your pieces overwhelm them.
White's Alternative: exd5 and the Quiet Moves
While fxe5 is most popular, White can also capture on d5. The move exd5 (68,508 games) scores a poor 47.3% for White — you are already doing well out of the opening. You simply recapture with your queen, knight, or bishop, maintaining active piece play. Other passive tries like Nf3 (18,739 games, 45.9% for White), d3 (13,689 games, 45.0%), and especially d4 (3,581 games, 42.3%) all give White worse results. In each case, you can comfortably develop, maintain the tension in the centre, and enjoy easy equality or more. The engine confirms that White should prefer fxe5 — everything else gives you at least a pleasant position.
The Mistakes to Watch For: d4 and Nxd5
Two moves are serious errors that you should be ready to punish. If White plays d4, the engine calls it an inaccuracy, losing about 0.8 pawns of advantage. In that position, you can play ...exd4 or ...Nxe4 with active play. The worse offender is Nxd5 — a full mistake that loses roughly 1.1 pawns. After White grabs the knight on d5, you recapture and enjoy a big lead in development and central control. Only 2,984 games reached Nxd5, and White scored a miserable 39.5% from there. When White plays these moves, focus on rapid development and opening lines — your pieces will be faster and more dangerous.
What This Opening Gives You as Black
The 3.Nc3 line of the King's Gambit Declined is a perfect choice if you want a solid but active response to White's aggressive 2.f4. You don't have to memorise the razor-sharp lines of the accepted King's Gambit. Instead, you get straightforward central play: you contest d5 immediately, develop naturally, and often end up with pressure against White's slightly loose kingside. The statistics show you score just above 50% in practice, and the engine agrees you have a tiny edge. It's a practical, low-risk way to meet the gambit and steer the game toward positions you'll understand intuitively.
