Overview

Sicilian Defense: Closed, Botvinnik Defense, with f4 is a specific line in the Semi-Open Games family (ECO B25), 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 12 plies — specifically the moves 1. e4 c5 2. Nc3 Nc6 3. g3 g6 4. Bg2 Bg7 5. d3 d6 6. f4 e5.

The line refines Sicilian Defense: Closed, which traces back to the root opening King's Pawn Game.
