Mar-29-03  Shadout Mapes: What? What's wrong with 29.Rxe7?
Mar-29-03  booman: Well as a 1400 player I would take the Queen (g).However Rf4+ then black has to move the Queen to block the check with Qf7 then Rxf7 and black can get ready for another check and loses his knight or something of that nature..(or if Kh7 or Kh8 then..Rh4 checkmate)just a beginners opinion...I still would have took the queen(g)..even though Rf4 I believe, is the best move for white...
Mar-29-03  tayer: I think that because 29. Rxe7 ... 30. Rxd7 white has one extra bishop, but after 29. Rxf4+ Qf7 (to avoid Rh4#) 30. Bxf7+ Kf8 31. Be5+ ... 32. Bxb7 white has an extra rook. White will win in any case.

  Sneaky: Tayer's line looks right. Either 29.♖xe7+ or 29.♖f4+ should be good enough to win; but 29.♖f4+ is the strongest so of course the metallic monster plays that move.
Nov-07-03  TheSaintofElsewhere: I think you guys missed the point on this one.... Qf7 Rxf7 Nf6(otherwise Rf4 with mate to follow) Rxf6+ Kh8 Rf4 and black cannot prevent mate Actually Black can cover the f7 square 2 more times by saccing both rooks but it still ends in mate. A nice windmill with a "quiet move" as the threat, of course the computer would see this, where us humans have trouble.
Nov-24-03  tayer: After 29. ... Qf7 30. Rxf7 Rxb4 Ivanov can prevent the immediate mate, but he is still hopeless.
Nov-24-03  mack: An almost human-like computer...
Jan-29-05  Glycerius: Ivanov withdrew from the tournament after this game; he was apparently quite upset and perhaps not a little embarrassed.
Apr-28-07  brainof7: if Q f7 BxF7+ And Kh8 Rh4++ (the mate is why he withdraws) and if Kh6 instead, Bd7 + dc. winning the rook.
May-11-10  Marmot PFL: "A remarkably impressive win against the strong Canadian Igor Ivanov, a man who once defeated Karpov. Watch closely, this may be the future of chess." Raymond Keene in the Spectator. Of course today any cheap laptop could play this game, but for 1988 it was remarkable.

  Phony Benoni: This game is actually from the 1988 US OPen in Boston, unless somebody pulled a fast one on the tournament bulletin editors.

  perfidious: <PB> Had not looked at the date of this game; but it is obvious on examining it that the game was indeed played at the US Open-that event ended 19th August 1988.

I have long since lost track of all my game scores from this event, but as noted elsewhere, I believe my loss to the computer was the night before.
