I haven't seen any GM analysis, but I did look at the position briefly with Fritz. Here's what I found: After 21. Ngxe5 22. Bxe5 Nxe5 23. dxe5 Qc7 it's difficult for White to defend the e-pawn, for example 24. Qe3 Bc5 25. Qg5 Be7 and now White either has to repeat moves or hand Black a big initiative. An example line is 26. Qxg7 Rdg8 27. Qf7 Rxg3 28. Qxe6+ Kb8 29. O-O-O (29. Qxa6?! Qxe5). Fritz thinks White is fine, but maybe Kasparov wanted to keep things a bit more under control. If the above variation scared Kasparov, he could have played the simpler 24.O-O-O Qxe5 25. Kb1. White is doing well here - I don't know why Garry wouldn't want this position. I didn't bother to look at 22. dxe5 d4, but I'm guessing Black is fine there. -Peter
