Zukertort Opening: Double Fianchetto 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 Zukertort Opening: Double Fianchetto Attack

Play White's moves of the line from memory — 1. Nf3 Nf6 2. g3 g6 3. b3 Bg7 4. Bb2 O-O 5. Bg2 d6 6. O-O — and the trainer plays Black's replies; "Play the other side" turns it around.
