Queen's Gambit Declined: Tarrasch Defense, Stoltz Variation 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.

Play Black's moves of the line from memory — 1. d4 d5 2. c4 e6 3. Nf3 c5 4. cxd5 exd5 5. g3 Nc6 6. Bg2 Nf6 7. O-O Be7 8. Nc3 O-O 9. Bg5 Be6 10. Rc1 b6 — and the trainer plays White's replies; "Play the other side" turns it around.
