1. b4 vs 1. g4


It is worth mentioning that the Grob opening has some pretty sneaky traps!

The Sokolsky is far more sound than the Grob.
The Sokolsky is equal with best play from both sides. The Grob gives Black the advantage with correct play.

I would prefer b4 too. I'm comfortable with sacrificing the b pawn in poisoned pawn variations. g4 looks early weakening of the kingside.

This is like asking if you want to surprise your opponent like the Romans did to Hannibal at Cannae (where Hannibals double envelopment wiped out an army) or if you want to surprise your opponent like the Germans did to Napoleon at Austerlitz (when a delayed attack on a key hill split his opponents and left them trapped out of position).
You can play standard openings and leave the book somewhere in the first ten moves and still have a good game. You should surprise your opponents that way!

Why not both? 1.g4 b5!?
Maybe you mixed them up? The Grob weakens the kingside so white would be happy castling queenside, while in the Sokolsky white would castle kingside


Supporting g4 with both f3 and h3 is terrible, the dark squares are completely trashed and the LSB is locked in.

How would you know?
OK, here's the clearest example:
Even if white avoids the checkmate though, the weaknesses are permanent and would give black a decisive advantage. The only possible benefit of moving the g-pawn to g4 at this stage is so that the bishop can be placed on g2 (of course begging the question of why not play the better move 1.g3?). Playing f3 then completely defeats the entire point of the opening is there ever was one. Even f3 is not played, the h3 move permanently weakens g3 which gives black a target to attack.

I'm sure I could achieve such a setup and still beat you.
Feel free to do so.

I would say that 1. b4 can possibly transpose into familiar positions. In some openings, pushing the b-pawn is part of the plan. I wouldn't play it that early but it is definitely better than 1. g4 where black gets a good position even if doesn't know anything.
The funny thing is that the grob's main trap doesn't even work.
