Kibitzer's Corner
Jul-05-06  RookFile: If memory serves, Fischer was thinking about a winning variation in this game, but a photographer snapped a picture, and Fischer lost his train of thought.
Jul-05-06  KingG: The most ridiculous excuse yet.
Jul-05-06  RookFile: Yeah, almost as bad as resigning in a drawn position.

  Pawn and Two: In the tournament book, "Second Piatigorsky Cup", Donner stated after Black's 29th move: <Black has not played very cleverly and is in a bad position. After 30.Qb1! he probably loses another pawn.>

Then after White's 30th move, Donner stated: <After touching the bishop Fischer sat for seconds with his finger on the piece desperately looking for another move. He had seen the point at the last minute - as usual - but there is no other move! The exchange of queens leads to a dead draw.>

Regarding Donner's recommendation of 30.Qb1, 30.Qe2 and next Bd3, appears to be a stronger continuation.

Jul-05-06  Marmot PFL: 16...Nxe3 looks premature. My advice is when in doubt play Rae8.

Jul-06-06  Hesam7: A twin game: Fischer vs J H Donner, 1965. It is interesting that Fischer is the first player to deviate.

Nov-06-09  WhiteRook48: 30 Qd3
Nov-06-09  GreenFacedPatzer: Really dumb question:

Why doesn't black play 16 ... Bf3?

There must be some escape from the immediate mate threat, since Fischer allows it and Donner plays something else, but for the life of me I can't see how white would escape checkmate.

Nov-06-09  Benzol: 16...Bf3 17.Qf1 stops the mate.
Nov-06-09  GreenFacedPatzer: Duh!

Thanks <Benzol>. It's good to be able to ask questions here, where it seems the average user is at least 500 elo stronger than me. :)

Nov-06-09  AnalyzeThis: Hey, good for you, green. You knew that Fischer couldn't have overlooked this if it was any good. A lot of people haven't learned that yet.
Oct-11-11  Everett: Position after 30.Bd3 is lesson #49 in "You vs Fischer" by Khmelnitzky. Recommended.
