Yes, that makes sense until this is played:
Now any lower rated opponent is going to have trouble.
1. Black is fine after 7...0-0 (8.Bh6 ? Ng6).
2. Though I know close to nothing of the Winawer, I am pretty sure 7...Ne7 is not the main move.
7...Ne7 and 7...Qc7 are the most popular replies. 7...0-0 is the Warsaw Variation. It is an obsecure sideline with very few good results in my database. Wolgang Uhlmann apparently dislikes it, but then again he is a very classical player. Moskalenko thinks it's playable, but he is also of the same opinion as Uhlmann.
I probably got the move order wrong, but that's the idea.
7. b4 looks extremely odd.
