French Defense: Tarrasch Variation, Open System 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 French Defense: Tarrasch Variation, Open System

The Open System of the Tarrasch Variation is 1.e4 e6 2.d4 d5 3.Nd2 c5, Black's way of breaking open the centre at once against 3.Nd2 in the French Defense. Play Black's moves of the line from memory — 1. e4 e6 2. d4 d5 3. Nd2 c5 — and the trainer plays White's replies; "Play the other side" turns it around.
