Benoni Defense: Old Benoni, Mujannah Formation 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 Benoni Defense: Old Benoni, Mujannah Formation

Play Black's moves of the line from memory — 1. d4 c5 2. d5 f5 — and the trainer plays White's replies; "Play the other side" turns it around.

"Drill all" adds the 1 named line that continue it, such as Benoni Defense: Benoni-Staunton Gambit.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Benoni Defense: Old Benoni, Mujannah Formation page, or pick another opening in the opening trainer.
