Mar-29-04  Tigran Petrosian: Very nice.
Mar-29-04  Vischer: Tigran Petrosian, Chessgames.com says you can't make your user name the same as an actual GM, unless you are them. I doubt you are really Petrosian.

  tamar: Tigran Petrosian is okay to use <Vischer> because it is the name of a non-living GM. Petrosian died August 13, 1984. There is another Tigran Petrosian currently, but he is so far only a strong master. "3. Do not name yourself after a famous living chessplayer (unless you are really him or her!) Likewise, please do not put "GM" or any other chess title in your handle unless you have actually achieved that title."
Mar-29-04  Vischer: Good point.
Mar-29-04  Tigran Petrosian: Thank you tamar. I am just a big Petrosian fan.

  keypusher: Wow, whotta game! Black certainly pushed hypermodernism to its logical extreme here. :-)
Feb-04-06  DAL9000: This really should be game of the day sometime. I've never, ever seen a pawn structure even remotely like the one you see after move 27. Yowza.
Feb-04-06  Jim Bartle: It's already been Game of the (Half) Year, as best game from Informant 13.
Apr-16-08  ToTheDeath: For goodness sake- 43.Qc4+ Kh8 44.Qxa4 Rb1+ 45.Kc2 Rxh1 46.Qf4 should hold the draw without difficulty.

  An Englishman: Good Evening: Fascinating game! Both players must have had enormous difficulty navigating the complications. After 27.gxh4, what do you think of 27...Rf4!? with the idea of 28...Rfxd4 and invading with doubled Rooks?
Apr-17-08  ToTheDeath: <An Englishman> 27...Rf4? 28.b7! as the pawn becomes a menace.
Jan-17-10  butilikefur: ? why didn't Black play <25...Nc7+ 26. Bxc7 Rxc7 27. Qd4> 27. b7 Rd8 28. Qd4 (28. Qe5 28...Bc2+ [28...Rxd6+ 29. Qxd6 Bc2+ 30. Ke1 Rxg2+ 31.

Kxf2 bxc4 is an easy endgame - 32...bxc4 33. Ra1 allows an evil trick] 31...Re2+ 32. Kf3 Rf8+ 33. Kg4 e5 should win) 29. Kc1 Bg5+ etc. <27...Bc2+ 28. Kc1 Bg5+ 29. Kb2 Bf6>

  Open Defence: < ToTheDeath: For goodness sake- 43.Qc4+ Kh8 44.Qxa4 Rb1+ 45.Kc2 Rxh1 46.Qf4 should hold the draw without difficulty.> After 46...Ra8 I dont think so, if the King moves say

47.Kb2 (if Kd2 then Rxh2+) Rd1 48.Qg4 Rdd8 and the White King will continue to be harassed

If 47.Kd3 Ra3+ 48.Kc2 Rxh2+

So I'm not sure 43.Qc4+ was much better

43.Qc4+ Kh8 44.Qxa4 Rb1+ 45.Kd2 i.e. the line given in the computer annotated score, after 45..Rxh1 46.Ke3 Rxh2 I think Black is winning comfortably
