Grob Opening: what to do after 1.g4
The Grob Opening is a sharp and unusual first move, but the position it creates is not easy for White. After 1.g4, Black is already a long way from trouble if they answer accurately, and the engine’s preferred reply is very direct. That makes this a useful drill if you want to understand what happens when you push the g-pawn early: development, central control, and king safety still matter a lot. Play the position below as White and see whether you can handle the best defence.

The move 1.g4 grabs space on the kingside, but it also loosens your king before your pieces are ready. In the resulting position, Black to move has the more comfortable task, and the evaluation is -1.25. That means you are already facing a clear, lasting disadvantage. The lesson here is not to force tactics at any cost, but to understand how much you have given away by moving the g-pawn so early.
Black’s most accurate reply
The engine’s best move is d5, and the listed continuation is d5 g5 h6 d4. That tells you what Black wants: simple central play and rapid use of the space you have weakened. If you are White, your job in the drill is to meet that kind of direct central response without losing even more time. In openings like this, every tempo matters because development and king safety are already delicate.
What the database says
This exact position has been played in 7,464,594 games on Lichess, so there is a huge practical sample behind the drill. White wins 48.3%, draws 3.8%, and Black wins 47.9%. The results are surprisingly close, but the low draw rate shows that games here often become decisive. That is a good reminder that the opening can become messy very quickly, even when White has started with an offbeat move.
The replies you will meet most often
The most-played continuations are d5 (2,544,256 games, White scores 48.9%), e5 (2,408,643 games, White scores 48.3%), e6 (483,961 games, White scores 47.6%), c5 (439,163 games, White scores 47.4%), g6 (282,025 games, White scores 46.5%), and d6 (268,714 games, White scores 48.9%). The most important takeaway is that Black has several active ways to respond, and none of them promise comfort for White. Your drill is about learning to face that pressure without drifting further behind.
Common mistakes to know
The database flags e6, c5, and g6 as inaccuracies here. Each one is said to lose about half a pawn compared with the best move, and in each case d5 was better. If you are White, that helps you understand which replies are slightly less accurate from Black and where the engine may give you a bit more room. Still, the position remains unpleasant for you overall, so the safest mindset is to stay practical rather than hopeful.
