Overview

Sicilian Defense: Moscow Variation, Haag Gambit is a gambit, classified under ECO code B52 within the Semi-Open Games family. As with all gambits, one side sacrifices material early — usually a pawn — in exchange for development, open lines, or initiative.

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.

Play reaches this position via 1. e4 c5 2. Nf3 d6 3. Bb5+ Bd7 4. Bxd7+ Qxd7 5. O-O Nc6 6. c3 Nf6 7. d4, after 13 plies of opening development.

It is a variation of Sicilian Defense: Moscow Variation, Main Line, which itself descends from the root opening King's Pawn Game.
