  I don't mind playing 15...c6, but I think 15...f5 or even 15...Kh8 is better.

For 15...f5 i have
16.d6 [oops, not d8 - mz] Kh8 but then 17.Bxb6 cxb6 18.Bb5 Qd8 19.d7 a6 20.Be2 b5 21.exf6 Rxf5 22.Ne4 Bf6 23.Nxf6 exf6 24.f4 Qf8 25.Qe6 +-

I only gave 15...Kh8 a passing glance because it seemed to me that 16.a5 was simply to serious a threat to ignore. It looked to me that Black would loose all mobility on the Q-side and have nowhere for counterplay.

It would be interesting to explore these ideas at another time.

for what it is worth, from Nigel Davies' the grünfeld defence

15...c6

Black can also undermine the pawn chain at its base. The immediate 15...f5 looks risky after 16. d6+ Kh8 17. dxc7 Qxc7 18. Nb5 Qb8, and now 19. Bd4 might be White's best (19. exf5 Rxf5 was unclear in Century-Nimzo 7.32, Computer Tournament 2000). A more circumspect idea is to prepare ...f7-f5 with 15...Kh8, when Mohr-Smejkal, Altensteig 1990, and Sosonko-Timman, IBM 1975 both went 16. Nb5 f5 17. Bd4 fxe4 18. Bxg7+ Kxg7 19. Nd4 exf3 20. Ne6+ Kg8 21. Bxf3 Bxf3 22. Rxf3 Rf6, when White has adequate compensation for the pawn, but no more than that.

Hi team
Yes I agree 15...f5! [or even 15...Kh8] is better.
