What is the idea behind Schuhler Gambit? The Schuhler Gambit is a line in the Sokolsky Opening.
[FEN &quot;&quot;]

1. b4 c6 2.Bb2 a5 3.b5 cxb5 4.e4

White gives away their b-pawn here. Stockfish claims this actually gives a small advantage to White, (although I analyzed only to depth 25) while bxa5 gives a small advantage to Black.
Why is it good and what is White's plan?
Trades off time and space for a side pawn that loses more time for black if they try to keep it.
c6 was not a good response for black on move 1
in the position shown master results show an 80% win rate (draws =1/2)
for white with zero losses
black would do far better with 1 ...   d5 e5 or nf6
