About the Boleslavsky Variation

The Boleslavsky Variation is named after Isaac Boleslavsky. It answers the quiet 6. Be2 of the Classical Sicilian with 6...e5, gaining time on the d4-knight at the cost of a backward d6-pawn and a hole on d5. The older 7. Nb3 is still the commonest reply online, while 7. Nf3 h6 8. O-O Be7 9. Re1 O-O 10. h3 is the modern treatment. 7. Nxc6 is the Louma Variation. Black scores slightly better online, and the engine sees rough balance.
