Position in Forsyth-Edwards Notation (FEN)
Moves: 1. d4 b5
ECO code: A40
Parent: Queen's pawn opening

1...b5 · Polish defence

[edit | edit source]

Black prepares their queen's side bishop to be fianchettoed, and Black's pawn on b5 prevents White from playing c4.

However, this allows 2. e4 and White is able to occupy the centre with both pawns.
