The engine's top suggestion for Black is h5. That's right — Black attacks your g-pawn immediately. The full engine line runs h5 gxh5 Qa5 Nc3, after which Black has traded a pawn for development and pressure along the a5-e1 diagonal. Your g4 pawn is a magnet for trouble in this opening, and Black's best plan exploits it directly. Even though you're already worse, recognising this plan helps you anticipate what strong opponents will do. Only 8,744 out of 84,966 games saw h5 in the database, meaning most Black players pick something else — which gives you chances.
What Black Actually Plays (and Your Results)
The most common Black move is e5, played 32,786 times. White scores 46.3% — poor but not hopeless. Next is Nf6 with 15,140 games and White scoring 48.8%, close to even. Then h5 (8,744 games, 45.0%), e6 (7,270 games, 49.3%), h6 (6,025 games, 48.8%), and g6 (5,007 games, 46.1%). Notice that White's best winning percentage comes against e6 and Nf6 — both of which are rated as inaccuracies. If your opponent plays solidly with h5, your win rate drops. If they give you a helping hand with a weaker move, you can claw back nearly to equality.
Punish Black's Mistakes
The analysis identifies three common Black errors in this position. Nf6 is an inaccuracy that loses about 0.8 pawns of advantage — better was h5. e6 is also an inaccuracy, also losing ~0.8 pawns. h6 is worse: a full mistake costing Black ~1.1 pawns. If Black plays h6 instead of h5, you've gained more than a pawn's worth of advantage back. Why? Because h6 is a passive waiting move that does nothing to challenge your g4 pawn or your bishop on g2. You can then continue developing — perhaps with d3, Nf3, and castling — and enjoy a much more comfortable position. Recognise these moves and seize the chance to equalise.
The Big Picture: Grob Gambit Survival
Across 84,966 games your actual results are nearly dead even at this position: White wins 47.5%, draws 3.9%, Black wins 48.6%. That's a White scoring rate of about 49.5% — almost exactly half. For an opening that gives Black a ~1 pawn advantage by engine reckoning, your practical chances are much better than the evaluation suggests. The reason: at club level, Black rarely finds the best plan (h5). They often play e5 or Nf6 or even h6, and you can respond with solid development. The drill below lets you practice against both the critical h5 and the weaker alternatives so you gain confidence in this offbeat line.

Frequently asked questions
Why does Stockfish say I'm clearly worse as White after 1.g4 d5 2.Bg2 c6 3.h3?
The evaluation -1.04 reflects Black's big centre and your exposed kingside. Black's best move h5 attacks your g4 pawn immediately. Most opponents don't find this plan, though, and White actually scores 47.5% wins — not far from Black's 48.6% — in real games. The engine sees a clear advantage for Black, but practical play is much closer.
What's the best move for me as White after Black plays h5?
You'll likely capture with gxh5. The engine continues Qa5 Nc3 — Black develops with check and pressure. It's an uncomfortable line but you can survive with careful play. Against other moves like e5, Nf6, or e6 you have a much easier time developing normally.
Which Black moves are mistakes I can exploit as White?
Nf6 and e6 are inaccuracies costing Black about 0.8 pawns of advantage. h6 is a full mistake costing about 1.1 pawns — a passive move that does nothing to challenge your setup. If you see h6, continue with d3 and Nf3 and you'll have a solid position.
