Bishop's Opening: Boi Variation 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 Bishop's Opening: Boi Variation

The Boi Variation, also called the Classical Variation, is 1.e4 e5 2.Bc4 Bc5, Black's symmetrical reply to the Bishop's Opening. Play Black's moves of the line from memory — 1. e4 e5 2. Bc4 Bc5 — and the trainer plays White's replies; "Play the other side" turns it around.

"Drill all" adds the 15 named lines that continue it, such as Bishop's Opening: Lewis Gambit, Bishop's Opening: Philidor Variation, Bishop's Opening: Stein Gambit, Bishop's Opening: McDonnell Gambit, Bishop's Opening: Lopez Variation, Bishop's Opening: McDonnell Gambit, La Bourdonnais-Denker Gambit, Bishop's Opening: Lewis Countergambit, Bishop's Opening: Lopez Gambit.
