In most line the grunfeld is full of possibilities. Be it in an endgame, a tactical position or a strategical battle.

But I don't know of any variation as dry as this one.

So what's the most interresting winning attempt against it ?

I'm studying Bd7 right now, delchev recommandation of Qa5.
Nc6 seem drawish everywhere after an exchange on c6 that leaves us with a weak pawn. Nd7 seem weird.
