9...Ne8 was seen in Korchnoi- Nemet, 1994. 10 Be3 f5 11 f3 f4 12 Bf2 h5 13 c5 g5 14 a4 Ng6 15 a5 dxc5 16 Bxc5 Nd6 17 Nd3 Rf7 18 a6 b6 19 Bxd6! (Korchnoi-Nemet, Switzerland 1994). Its possible 15...dxc5 deserves a dubious appellation.
Has Kramnik been adopting the fianchetto system against the King's Indian lately? Pardon me, I admit I haven't been tracking the latest trends in the KID for some time now. I've just returned from somewhat of a hiatus from chess you see. :)
The above game is interesting, thank you for bringing it up! I am going to have a look at this game, there a clear faults in black's approach to the KID here (also black is 130 elo points weaker).
9 ... Ne8 10 Ne1 f5 11 exf5 gxf5
12 f4 Ng6 13 g3 Bd7 14 Ng2 Qe7
15 Bd2 Nf6 16 Qc2 exf4 17 Nxf4 is standard stuff
But I agree with you on; on principle, e8 is a poor square for a knight. I prefer to stay away from 9...Ne8
