Move 32 would probably be better, since White's <32. Rd1> does not seem best. Haven't put the position through silicon analysis, and I'm not at-all sure of the tactics, but 32. Qc3 seems better, for example.

<Crowd-favorite GM Gregory Kaidanov fell back to an even score with his second loss in a row. <“After two long games against Gata and Hikaru, I felt very tired today,”> he said about his loss against GM Robert Hess. Kaidanov was surprised by Hess's opening choice, and forced into a deviation due to a curious incident. After nine moves, his game was exactly like Onischuk vs A Ramirez, 2012. Onischuk played 10. e4, and Kaidanov felt forced to play a different line. <“It would look like we are just copying each other's games,”> he explained. <“We try to prevent cheating in many different kinds of ways, but we can't prevent that.”> He said copying another player's moves willfully is <“kind of like cheating”> and while not expressly prohibited, the veteran decided he needed to play a new variation. Hess found a way to trade his queen for three of Kaidanov's active minor pieces, then unearthed a nifty queen trap based on various forks and discovered attacks.>>

May-14-12  Marmot PFL: After 18 Bg5 Rxd5 too many things are attacked. 18 Be3 is safer, maybe then the wrong rook is on e1 but that's not so serious.
