French Defence

Winawer Poisoned Pawn

The sharpest line of the entire French, where after 7.Qg4 Qc7 8.Qxg7 Rg8 9.Qxh7 cxd4 White grabs both wing pawns while Black gets a huge lead in development and open lines. One of the most theory-heavy variations in chess - both sides walk a tactical tightrope where a single inaccuracy decides the game.
