Polish Defense trainer

Back to the opening, all openings to practise or my repertoire

Type a move and press Enter: e4, Nf3, O-O, or from and to squares like g1f3 (e7e8q to promote). The board is also played with the mouse.

Practise the Polish Defense

The Polish Defense is 1.d4 b5: Black plays ...b5 at once, by analogy with the Polish Opening, 1.b4. Play Black's moves of the line from memory — 1. d4 b5 — and the trainer plays White's replies; "Play the other side" turns it around.

"Drill all" adds the 1 named line that continue it, such as Polish Defense: Spassky Gambit Accepted.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Polish Defense page, or pick another opening in the opening trainer.
