Hi Dieter,
This position is a definite crush for white.

No surprise. Near the end Phalanx likes Bxd4 instead of Bf4. The mate is
probably not far off in any event. I'll take your word that's it in 19:)
As far as the French goes generally (Winawer included), I agree that it's a poor
defense for most engines. The pawn formation is too threatening against the
k-side, the e-pawn is cramping, taking f6 away from the knight. Bxh7 tricks are
frequent as well as pawn storms making for quick wins. Queen-side castling is
usually the answer for Black ...
Cheers,
Jim
