Quote:Hello,
I believe that this Line at Grandmasterlevel is suspect, but the Level of my Pupil is much lower... about 1700 Elo.
With this Line i think its really possible to play for a win against same Level. Not everyone knows much about Theory.
I hope he can improve his tactical skills with this line. Most Player in this level play 6.Bd3 or like this. And he can study
how to handle with unbalanced Material ( Rook against Bishop and Pawn). Thats the only reason we start to study this Line.

The main problem is that White just need to know one or two short little lines and they can already achieve a nice position against the Pin Variation. Besides that early Qg4 variation that you've mentioned earlier, there's also the very good line 6.e5 Nd5 7.Bd2 Nxc3 8.bxc3 followed by ideas like Qg4, h4-h5, Bd3, etc... You said that most people play 6.Bd3 at your pupil's level, but the problem is if your pupil happens to face against someone who knows 6.e5 (which is not much to learn to begin with), then he's already half busted. If his/her opponent then goes on to play that line that I had mentioned just now, which is recommended in popular books like NCO and Beating the Sicilian series just to name two, then white ends up with a comfortable advantage and denying your pupil from any exchange sacs too.
To me, that's just too risky. It's like hoping that your opponent does not know the line, which isn't that difficult to memorize to begin with.
If you want your pupil to try this opening nevertheless, then you can always tell him to do so in training games or on the internet, where the result does not matter. But in serious play, I really don't recommend it. The risk is just too high. If you want your pupil to experience material imbalances, then there's always something like the Dragon, where the Rxc3 exchange sac is a common theme and the Dragon is defintiely more playable than the Pin.
