Sicilian Defense: Boleslavsky Variation
Overview
Sicilian Defense: Boleslavsky Variation is a specific line in the Semi-Open Games family (ECO B59), arising from a recognised theoretical position.
The Semi-Open Games group covers semi-open games — replies to 1.e4 where Black declines the symmetrical 1…e5 in favour of an asymmetric pawn structure.
The line arises from 13 plies — specifically the moves 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 d6 6. Be2 e5 7. Nb3.
The line refines Sicilian Defense: Open, which traces back to the root opening King's Pawn Game.
