Chess Opening · A00
Grob Attack
For sub-1000 ELO players
The Grob Attack (ECO A00) starts with the unusual 1. g4, pushing a wing pawn instead of fighting for the center. Stockfish 17 at depth 25 evaluates this position at roughly -0.5 after the Kolibri Variation with 1. g4 d5 2. Bg2 Bxg4, meaning Black already has a clear advantage. Sub-1000 ELO players as Black often fail to punish this opening because they do not realize 2...Bxg4 wins a free pawn.
The Best Response
Moves to Play
White · Black alternating
1. g4 d52. Bg2 Bxg4White opens with the eccentric 1. g4, weakening the kingside and ignoring the center. Black plays 1...d5 to seize central space immediately. White follows with 2. Bg2, developing the bishop to the long diagonal, but 2...Bxg4 simply wins the g4 pawn for free since the bishop on c8 is now unblocked after the d-pawn moved.

These are the patterns we see in games below 1000 ELO. Fix these and you'll stop losing to this opening.
Not taking the free pawn
Sub-1000 players often hesitate to take the g4 pawn with their bishop. They worry it might be a trap, but it is simply a free pawn with no compensation for White.
Bxd5Playing too passively as Black
Beginners sometimes respond to unusual openings by playing timidly. Against the Grob, they might play quiet moves instead of grabbing the center immediately with d5.
d4Overextending on the kingside
Some sub-1000 players try to mirror White's aggression on the kingside instead of building a solid center. They push pawns forward when steady development is stronger.
c3Why This Opening Trips You Up
The Core Problem
The Grob Attack looks scary because beginners rarely see 1. g4. They freeze up or play random moves instead of grabbing the center and taking the free pawn on g4.
Before Your Next Game
When your opponent plays a weird opening like 1. g4, remind yourself that weird does not mean strong. Play d5 for the center, and take any free pawns. Simple chess wins here.
What to Study
Play through the line 1. g4 d5 2. Bg2 Bxg4 three times against a bot. Focus on taking the free pawn and then developing normally with Nf6, c6, and e6.
