3.f3
This way White wants to avoid main lines of the Gruenfeld Defense.
3...Bg7
Grischuk has nothing against the King's Indian, where due to the early advance f2-f3 White is practically forced to play the Saemisch Variation. [After 3...d5
4.cxd5
Nxd5
5.e4
in contrast to usual Gruenfeld positions Black cannot exchange knights on c3.]

9.Rc1
Usually White plays a less committing 9.Nc1, leaving open the possibility to castle queenside later on.
9...e6
A good reaction thanks to its flexibility. Black can choose later what pawn to advance further. For the moment Black's idea is to see White's intentions. [9...b5
would be a mistake, justifying 9.Rc1. White wins a pawn with 10.cxb5
axb5
11.Nxb5
Rxb5
12.Rxc6
]
10.b3
A solid move, but sooner or later White must take a decision about his plan.
10...Nd7
Again a tricky move from Black, practically forcing White to start active actions. The point is that now a quiet development 11.Ng3 with the intention Be2 and 0-0 is strongly met by 11...e5 12.d5 Nd4, with excellent position for Black.

Black has a pleasant choice between 14...Ng4 and 14...Nh5. 14...Ng4

12...Ne7
After removing the knight from c6 Black is ready for the advance b7-b5.
