Dutch Defense: Spielmann Gambit – Guide for White
You've played 1.d4 f5 2.Nc3 Nf6 and now you push 3.g4 — the Spielmann Gambit. You're offering a pawn to rip open the kingside before Black can castle. Stockfish evaluates this at -0.11, a dead-level position — neither side is better out of the opening. That means you're not gambling your chances; you're steering into an asymmetrical fight where your activity can outweigh the pawn. Across 642 games at this exact position, White wins 56.2% of the time. Try the interactive drill below to see how the engine responds and learn the ideas that make this gambit work.

The Spielmann Gambit is all about tempo and open lines. After 1.d4 f5 2.Nc3 Nf6, your 3.g4 challenges Black's most aggressive move (f5) head-on. If Black takes the pawn — which happens in 257 of 642 games — you get a half-open g-file for your rook and the chance to play moves like Nf3, Bg2, and h4 to keep the attack rolling. Your d4 pawn gives you a centre presence, and Black's king often gets stuck in the middle. Even though the engine says the position is level (-0.11), the practical statistics strongly favour you: White scores 54.1% after fxg4. That's the kind of edge club players can exploit.
Black's Best Reply (and What to Do About It)
The engine's top choice is 3…d5 — Black immediately challenges your centre instead of grabbing the pawn. The continuation runs d5 g5 Ne4 Bf4 (given by Stockfish). In this line Black returns the gambit pawn to set up a strong knight on e4. Practice this sequence in the drill so you're ready. Interestingly, in the 40 games where Black played 3…d5, White only scores 47.5% — so while it's the engine's recommendation for Black, it's not a line that's been crushing White in practice. If you face 3…d5, stay calm, play the natural developing moves, and trust your centre.
Punish Black's Most Common Mistakes
Here's where the Spielmann really rewards you. Black's most popular reply — 3…fxg4 (257 games) — is actually an inaccuracy that loses about 0.6 pawns compared to the engine's 3…d5. Even worse are 3…e6 (114 games, loses ~0.8 pawns) and 3…d6 (44 games, a full mistake losing ~1.2 pawns). Your job is simple: know that these moves are suboptimal, and don't panic when your pawn disappears on g4. After fxg4, for example, you just continue developing with Nf3 or Bg2, and your lead in development and open lines give you full compensation. The statistics back this up — White scores 60.5% after 3…e6 and 61.4% after 3…d6.
The Quiet Replies: Nxg4 and g6
Two other replies appear frequently. 3…Nxg4 (137 games) — Black grabs the pawn with the knight instead of the f-pawn. Here White scores 53.3%, a solid result. Don't chase the knight; instead, drive it away with moves like e4 or Bg2, and use your space advantage. And 3…g6 (35 games) is actually Black's worst-scoring option: White wins a crushing 71.4% of those games. After 3…g6, you can just take on f5 yourself (exf5) and enjoy a strong centre and open lines. The lesson: the Spielmann Gambit works best when Black cooperates, but even when they try to play solidly, you still get excellent practical chances.
