Polish Opening, with d5 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, with d5

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

"Drill all" adds the 5 named lines that continue it, such as Polish Opening: Baltic Defense, Zukertort Opening: Santasiere's Folly, Polish Opening: German Defense, Polish Opening: Myers Variation.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Polish Opening, with d5 page, or pick another opening in the opening trainer.
