Crushing the Grob Opening: Nc6 as Black
White plays 1.g4, and you immediately answer with the natural-looking Nc6 – attacking that pawn. When White continues 2.d4, you've reached one of the most important positions in the Grob. Here's the good news: you already stand better. Stockfish pegs this at -0.88, a clear plus for Black, and statistics over six thousand games barely give White a 46% win rate. The key is knowing what to do next – because several popular moves here are outright mistakes that throw away your edge. Let's see how to keep the pressure on.

White has played the bizarre 1.g4, weakening the kingside immediately, and then grabbed space in the centre with 2.d4. Your Nc6 already eyes the d4-square and puts pressure on White's centre. The engine gives you a -0.88 advantage — you are clearly better in this position. White's g-pawn is loose, their king is stuck in the centre, and you have not made any concessions. The question is: how do you convert this edge without letting White off the hook?
The Critical Move: d5
The best move here is d5, and the statistics back it up. From 3,259 games where Black played d5, White scores just 47.4% — but that number hides the truth: those games include all levels, while the engine knows d5 gives you a clean advantage. The idea is simple: strike in the centre immediately. After 2...d5, White's most common response is 3.h3 (protecting the g-pawn), and you continue with 3...h5, attacking the g4-pawn directly. White typically pushes 4.g5, and your position remains excellent. You've opened lines for your light-squared bishop, challenged White's centre, and kept your development flexible.
Three Mistakes to Avoid
The Lichess database reveals three common moves that are all mistakes here, meaning you lose your advantage: - Nf6 (565 games): This loses around 1.9 pawns of advantage. Developing the knight is natural, but it doesn't challenge White's centre and allows them to stabilise. - e5 (554 games): Costs you about 1.0 pawns. Attacking the d-pawn looks reasonable, but after 3.dxe5 or 3.d5 you've given White an easier game. - e6 (552 games): A smaller error at around 1.1 pawns lost, but still a clear mistake. This solid, quiet approach lets White breathe. The engine verdict is unanimous: d5 is the only move that keeps your advantage.
What the Numbers Reveal
Across 6,067 games at this exact position, Black actually outscores White: 48.9% Black wins vs. 46.4% White wins, with only 4.7% draws. That's remarkable for an opening where White is theoretically supposed to be worse — it shows that many Black players do find the right plan in practice. The worst-performing Black move among the popular options is b6 (359 games), where White scores 51.3%. And d6 (257 games) gives White 49.0%. Neither is a mistake like Nf6 or e5, but neither is as good as d5. Stick with the engine's recommendation and you'll be on the right track.

Frequently asked questions
Is 1.g4 a serious opening?
The Grob (1.g4) is considered a dubious opening at club level and above. After 1.g4 Nc6 2.d4, Stockfish rates Black at -0.88, a clear advantage. While White can try to muddy the waters, you should be better with accurate play from move two.
Why is d5 the best response to the Grob: Nc6?
Playing 2...d5 strikes immediately in the centre and prepares to attack White's weak g4-pawn with ...h5. It's a natural, principled move that develops your position while exploiting White's early pawn push. The engine confirms it as the only move that keeps Black's large advantage.
What happens after 2...d5 3.h3?
After 3.h3, you play 3...h5, attacking the g4-pawn again. White usually pushes 4.g5, and then you have several good options. Your centre is solid, your light-squared bishop can develop to f5 or g4 later, and White's kingside is a mess.
Can I play Nf6 against the Grob: Nc6?
You can, but the engine marks it as a mistake losing about 1.9 pawns of advantage. Developing the knight is natural, but it allows White to play e3 or Bg2 without being punished. Stick with d5 to maintain your edge.
