Polish Opening: Baltic 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 Opening: Baltic Defense

Play Black's moves of the line from memory — 1. b4 d5 2. Bb2 Bf5 — and the trainer plays White's replies; "Play the other side" turns it around.

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