Bad preparation, or just too much information?
You make the call. I'm referring to the game Ghane-Krivoshey from the 8th Dubai Open, when White followed theory for 24 moves, produced a novelty, and resigned after just two more moves. I'm not sure where his preparation ended, but it wasn't a success. Have a look here, and realize that if you play super-sharp lines without due preparation, Ghane's fate may be yours. (Advanced/960 Chess, anyone?)

black however knew exactly what he was doing having 'drawn' in this line against Xie Jun in 1997 - in the notes this game is given as a draw but surely a player as strong as Xie Jun would have seen that black is toast in the final position - any ideas?
Also in that game Gallagher suggests the big improvement for black 26.... Nxf3+!! 27. Bxf3 Qxh1+ 28 Kxh1 Nf2+ 29 Rxf2 gf2 30 Rf1 Ra4 31 Ba3 Rxc4 32 Rxf2 and black, with his rook and 5! pawns against 3 minor pieces, is better.
the sort of line that makes you want to give up your job and spend your time studying and playing the King's Indian!
There, my conclusion was that Black should not play 18...g3. But, well, it is not "written in stone". It is interesting that Krivoshey played all this with Black. He is one of the main experts of the 13.a4 line for White! Maybe 21.Qc2 Ng6!? is really critical? (Tsesarsky in CBM recommended 22.Rfb1.) As I remember, there was also a survey on this topic by Matamoros in the "New in Chess Yearbook".
In relation to TNs
1) is Z's 1.e4 c5 2.Na3 a TN? If not, when was it first seen?
2) I found a TN (or at least unknown to me, and I have tried to source it) in a rare line (move 6):
1.d4 Nf6 2.Bf4 c5 3.d5 Qb6 4.Nc3 e6 5.e4 Nxe4 6.Nb5 c4
absoulutely must get his book
so the jury's out on 21 Qc2 Ng6!? and now Tsesarsky's 22 Rfb1 or DM's 22 Rfc1
wonder what Krivoshey had prepared?
Alex: That whole line is pretty rare stuff: with 4.Nc3, I find only two games in Mega2006, after 4...e6, just one game, and then 6...c4 looks like a novelty. As for Zvjaginsev's 2.Na3, it's not a novelty - there were 17 games in Mega2006 with the move before he made it his own.
