Sicilian Defense: Frederico Variation
Overview
Sicilian Defense: Frederico Variation is a specific line in the Semi-Open Games family (ECO B27), 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.
It is reached after 6 plies of play, with the move sequence 1. e4 c5 2. Nf3 g6 3. d4 f5.
The line refines Sicilian Defense: Hyperaccelerated Dragon, which traces back to the root opening King's Pawn Game.
