Blackmar-Diemer Gambit: Diemer-Rosenberg Attack 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 Blackmar-Diemer Gambit: Diemer-Rosenberg Attack

Play White's moves of the line from memory — 1. d4 d5 2. e4 dxe4 3. Be3 — and the trainer plays Black's replies; "Play the other side" turns it around.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Blackmar-Diemer Gambit: Diemer-Rosenberg Attack page, or pick another opening in the opening trainer.
