French Defense: MacCutcheon Variation
Main Line
1. e4 e6 2. d4 d5 3. Nc3 Nf6 4. Bg5 Bb4
Overview
A counter-aggressive French Defense system — after 4.Bg5 Black answers with 4...Bb4, pinning White's c3-knight and threatening to capture the e4-pawn. The mainline 5.e5 h6 6.Bd2 Bxc3 7.bxc3 Ne4 leads to fascinating positions where Black has an outpost knight on e4 and White has doubled c-pawns plus attacking chances. Named after American master John Lindsay McCutcheon (1885) and revived by Soviet players in the 1950s. A serious surprise weapon for players tired of the Winawer.
