Modern Defense: Geller's System
Overview
Modern Defense: Geller's System is a named branch in the Semi-Open Games group of chess theory, classified under ECO B07.
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 g6 2. d4 Bg7 3. Nf3 d6 4. c3, after 7 plies of opening development.
In the opening tree, this line branches off from Modern Defense, 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.
