Sicilian Defense: Wing Gambit, Marienbad Variation
Overview
Sicilian Defense: Wing Gambit, Marienbad Variation is a sacrificial opening line filed under ECO B20 in the Semi-Open Games group. The defining idea is the early concession of material to seize the initiative and unbalance the 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 begins with 9 plies and takes 1. e4 c5 2. b4 cxb4 3. a3 d5 4. exd5 Qxd5 5. Bb2 to reach the canonical position.
In the opening tree, this line branches off from Sicilian Defense: Wing Gambit, Marshall Variation, part of the broader King's Pawn Game system.
Use the board to walk through every move, check how the position has scored on Lichess, or take it head-to-head against Stockfish.
