Is the French defense at a 3700 Elo level "completely refuted"?

For what it's worth, in high-level correspondence play, the French is considered highly suspect. Maybe black can draw with very accurate play, but certainly he has a much harder job than in either 1. ...

Why is this the best move?

10 . . . Nxe4 is best because it wins a pawn, while other moves only keep material equality (or worse, give away material). The move is a typical "desperado" sacrifice, introducing a line ...
