Grob Opening: Keene Defense, Main Line 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 Grob Opening: Keene Defense, Main Line

Play Black's moves of the line from memory — 1. g4 d5 2. h3 e5 3. Bg2 c6 4. d4 e4 5. c4 Bd6 6. Nc3 Ne7 — and the trainer plays White's replies; "Play the other side" turns it around.
