The French is a complex opening and can lead to a wide variety of middlegames. The Winawer after 3...Bb4 is Black’s most proactive option, immediately weakening White’s pawn structure by doubling their c-pawns.
While Black gets to play against the weak square d4, White often gets attacking chances on the kingside and a space advantage. Structurally, this line can lead to closed positions after ...c4, or open and dynamic play by white’s structural exchange dxc5. “My game selection is aimed at explaining the most important plans of these strategically complex positions.” (Author GM Ivan Sokolov)
