Polish Opening: all variations and ECO codes

25 named lines across 2 ECO codes (A00–A05). Source: the CC0-licensed lichess.org opening database.

The idea

White grabs queenside space immediately and offers the b-pawn as a gambit in some lines, aiming the fianchettoed bishop at the long diagonal from the first move. It’s an unusual, flank-first try that trades central influence for early space and piece activity on one side of the board.
