probably referring to 1.b4 e5 2.Bb2 Nc6 3.b5 Nd4 e3 when black loses a pawn.
Polish opening - Good or Bad

Oh that's right the black bishop can't take the b5 pawn because white's bishop is attacking the pawn and rook. I probably should have noticed that by now. Anyways, that's an interesting trap that I might try out in a future game. Not as big and flashy as some of the others, but a pawn's a pawn.

The Polish opening is an unusual opening for most chess players. Many of us find that developing the b pawn so early on in the game is often unnecessary in terms of centre development. So, What do you think?
Polish is hot garbage, I suggest you play the reverse polish, which is arguably the best opening.

if black books up, its probably just equal, but white's position is still fairly rich with good mutual chances and the level of familiarity and surprise can mean a lot. I have played 1.b4 vs IMs and GM's and have gotten good positions, sometimes +1 in fact. My first non-loss with a GM was with 1.b4.
I woudnt recommend you ONLY play it as white, but it can be fine addition for a white repertoire
What trap?
