Kibitzer's Corner
Feb-13-04  sacanimal: Chessgames.com: this is a duplicate game. Also, the tournament was held in Santa Monica, not Santa Barbara. I know; I was there. Spassky, Fischer, Petrosian, Larsen, Portisch, Reshevsky, Unzicker, Donner, Ivkov, Najdorf...and me (OK, I was just a kid who was there as a scorekeeper).
Feb-13-04  technical draw: Glad to see other kibitzers that lived that era and saw all those great players. I started playing in 1964 and got to see a lot of those "legendary" greats. I even lost to Najdorf.
Feb-13-04  marcus13: Is nadjork stile alive (never know)??
Feb-13-04  sacanimal: No, I'm sorry to say he is no longer with us: http://www.ishipress.com/najdorf.htm

Even in '66 he seemed rather old. During one of his games he first fell asleep and then fell out of his chair onto the stage.

Feb-14-04  drukenknight: honest to god it really looks like petrosian is fooling around. WHy does he bring the K to f8 anyhow? Last part of the game all his pieces are moving backwards.
Apr-22-06  stanleys: Think that 16...Bg7 or 17...Bg7 is necessary

  chancho: It took Petrosian quite a while to overcome the hold that Portisch had on him competively.
May-07-18  Toribio3: Petrosian was outplayed by the great Hungarian master, Lajos Portisch.
