  acirce: Resigning in a drawn position... 77...Kd3 78. Kg5 Ke4 79. Kxh5 Kf5=
Sep-14-05  mofoman: This is no draw.... Colle won...after 79. ...Kf5 80.Kh6 Kf6 81.h5 and now black king must choose between letting white king go or taking white pawn. white wins. Black must move because he got nothing left except his king :-)

  Mateo: I think acirce is right. After 81...Kf7 it is a draw. For instance, 82.Kg5 Kg7 82.Kf5 Kh6 83.Ke5 Kxh5 84.Kd5 Kg4 85.Kc5 Kf5 86.Kb5 Ke6 87.Kxa5 Kd7, theoretical draw.
Sep-14-05  sneaky pete: <acirce> is right, and it's still a draw after 80.Kh6 Kf6 81.h5 Kf7 82.Kg5 Kg7 83.Kf5 Kh6 84.Ke5 Kxh5 85.Kd5 Kg6 86.Kc5 Kf7 87.Kb5 Ke8 88.Kxa5 Kd8 (89.Kb6 Kc8). The black king has an alternative route (after .. Kxh5), the important thing is that he can reach c8 in time.
Sep-14-05  sneaky pete: See also Alekhine vs Reti, 1922.
Sep-14-05  mofoman: yes im sorry. he reaches c8 in time which makes it a draw. maybe gruenfeld didnt have enough time on his clock when he resigned this one.
Sep-14-05  RookFile: Good thing the champions of today
would never do anything as stupid as resigning in a drawn position.
Jan-20-07  GeauxCool: Queens 51. Pawn ending 58.Kf1. Both sides can promote, but White finds a way to exchange off the queens and then win.

  chessgames.com: A user submited this correction <This game has a mistake in it. I didn't know who else to tell. 72.70.Kg2 Ke2 71.g7 f3+ 72.Kh2 f2 73.g8=Q f1=Q 74.Qc4+ Ke1 75.Qxf1+ Kxf1 76.Kg3 Ke2 77.Kf4 1-0, but the position is drawn. It's 72.Kg3! which secures the win. Then the rest makes sense. 72...f2 73.g8=Q f1=Q 74.Qc4+ Ke1 75.Qxf1+ Kxf1 76.Kf4 1-0 Because of 76...Ke2 77.Kg5 Ke3 78.Kxh5 Kf4 79.Kg6 >

Can anybody confirm this, or is this just speculation?

  whiteshark: The whole thing remained undiscovered in the tournament book.

It's even more curious that Grünfeld missed the elementary drawing line, as the game has been adjourned after <72.Kh2>!

  Pawn and Two: <whiteshark> As you noted, the tournament book made no mention of the drawing line, even though the annotations for this game were done by Colle!

In the tournament book, Colle annotated only this game, and his win over Yates.

The game score in the tournament book matches the game score on this site. The fact that Colle did the annotations for this game provides additional evidence that the game score is correct.

Sep-05-09  LIFE Master AJ: <Chess Games> Its pretty well known that this is a drawn game, its analyzed in the "Encyclopedia of Chess Endings."

I cannot speak as to the exact conditions of the game or why Grunfeld resigned. (Perhaps someone out there has a copy of the tournament book?)

  Pawn and Two: <LIFE Master AJ> Regarding your question, please note my previous posting, and the posting by <whiteshark>.

The drawing possibility in the final position (77...Kd3! 78.Kg5 Ke4!), was not noted in the tournament book, even though the annotations for this game were done by Colle.

May-18-10  Tophie1984: Colle played 72. Kg3!
May-18-10  themindset: I'm not running it through a chess engine or anything, but I thought 48.Rxh7+! was coming for sure, it followed the plan from earlier.

Me neither, and me too! 48.Rxh7+ is a common decoy sacrifice. Colle clearly prefers the presence of his passed c-pawn over a possible reduced board having a clear-cut kingside pawn majority, but this is the structure he ends up with anyway.

49.Rd6 piling on the pinned Black rook looks good. Colle waited a move to play it, after both kings had moved. I'm struggling to find the necessity of the White king move on 49; it looks like an oversight to pass on the rook.
