I've been doing some prep for a tournament I have on Saturday and I've been going over my attacks against the Semi Slav. Normally, I play an Anti-Meran and Anti-Moscow sort of opening and I recently came across this variation in a Carlsen - Anand game where Magnus won. The variation is known as the Stoltz Variation, Shabalov Attack. I'm a career QG player and was wondering how effective this opening is in relation to the kind of compensation. Keep in mind I'm playing Class C and B players. I'll post the line below. Any and all comments will be appreciated. 

Bump. Sorry, I just want an answer.

It can get dangerous if black accepts on g4, but black is not forced to take on g4.  7...Bb4 is a strong move, giving the f6 knight the e4 square.  If black does take on g4 you get nice compensation.
