1. a3 a5 2. b4

The polish gambit!!!

There is also the flying orangutan:
1. f4 d5 2. b4! Qd6

And 1. e4 h5 2. d4 Nf6 is the Picklepuss defense.
What's your point?

try 1. g4!!! e5 2. f4!!! Best opening i've ever seen.

Give me some games for 1. g4, e5 2. f4 - please

Seems like lichess players with black haven't found the best move yet. ;)

Hou Yifan agrees with you:

Usually when I play the Grob, I prefer to enter the spike attack with 2. g5

1. a3 a5 2. b4 and after 2...axb4 3. Bb2 (3. axb4?? Rxa1) bxa3 4. Nxa3, white has a lead in development for the pawn.

Herrn Karpfenkopf:

1.g4 e5
2.f4 (???) - Qh4 mat!
