Sicilian Defense: Old Sicilian 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 Sicilian Defense: Old Sicilian

The Old Sicilian is 1.e4 c5 2.Nf3 Nc6, one of Black's three main second moves in the Sicilian Defense, alongside 2...d6 and 2...e6. Play Black's moves of the line from memory — 1. e4 c5 2. Nf3 Nc6 — and the trainer plays White's replies; "Play the other side" turns it around.

"Drill all" adds the 67 named lines that continue it, such as Sicilian Defense: Open, Sicilian Defense: Nyezhmetdinov-Rossolimo Attack, Sicilian Defense: Löwenthal Variation, Sicilian Defense: Accelerated Dragon, Sicilian Defense: Accelerated Dragon, Modern Variation, Sicilian Defense: Lasker-Pelikan Variation, Sicilian Defense: Nyezhmetdinov-Rossolimo Attack, Fianchetto Variation, Sicilian Defense: Kalashnikov Variation.
