1. b4 vs 1. g4
Sort:
As is your mind blocked Pfren.
The polish is strange but prepares Bb2 and the Grob prepares Bg2😒🙄
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.
