Here is some 3 minute crafty analysis of the pivotal part of the game. The move
in the EPD record marked as 'bm' is actually the move that was played (whatever
that was). Sometimes, it should clearly be the 'am' ;-).

Up to here, we are basically even and playing according to plan -- black even
has a slight edge according to a short search by Crafty:

Here is the fatal mistake --> h5 should be the move instead of Nxg4 which should
really be the 'am' for sure. It is fairly difficult to avoid Nxg4.

In short, I think GM Gulko made one single mistake and a very forgiveable one at
that. Namely, here:
4r3/pb1qbk2/1pn1pnpp/8/3P1BB1/2P5/PP2Q1PP/R4RK1 b - - am Nxg4; bm h5; id
"Shredder/Gulko 3-20-02";
