=French Defence, Winawer Variation= This is the main line of the Winawer Variation of the French Defense. The Winawer is a sharp and tactical variation of the French. White sometimes attempts to take the undefended g-pawn with Qg4. 6...Ne7 is a natural developing move, and 6...Qc7 backs the c-pawn and develops the queen to a good square.
