[Going through the Nb6 lines, I realised that White must find some way to activate his centre pawns not only to gain space but also to ward off the active Black N on d5 or f5. . Black can achieve c6-c5 without concessions, his pieces become well placed. GM Naer shows good technique in doing so.
11.Re4! Played to prevent c6-c5 by setting up Bf4. Nice idea!

[GM Michael Adams fared less well with
11...Nd5 12.Qf3 Nf5 13.Qh3! h5 14.Qf3 Qd8 15.h3 Qe8 16.Nc4 b5 17.Na5 Although he managed to turn the tables and win later. Chandler,M-Adams,M/London 1988/TD/0-1 (42)]

12.Ngf3 c5 13.dxc5 Qxc5 14.Qe2 Rd8 15.Bd2?!

[15.Bc2 With the idea of Bb3 is better.
15...Nd5

(15...Be6 16.Ng5)

16.Bb3]

15...f6! 16.Bxf5? One shouldn
t surrender the B pair so easily.

[16.Ng4 e5 17.Rad1]

16...Bxf5 17.Be3 Qc8 Now White is forced to give up the other B as well.

31...Kxg6 32.gxh5+ Kxh5 33.Nf5 Bf8 34.b4 Kg6 35.Ng3 Bh6 Now, the game is virtually over with Black
s centre pawns becoming mobile.
36.Rcc2 Bf4 37.Kf2 f5 38.c4 Bxg3+ 39.Kxg3 Be4 White just had enough suffering.
