Overview

Sicilian Defense: King David's Opening is a specific line in the Semi-Open Games family (ECO B20), 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 3 plies of play, with the move sequence 1. e4 c5 2. Ke2.

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