Kibitzer's Corner
Nov-24-04  OverDjinn: In the November 1988 issue of Chess Life, Eliezer Agur called this game an “unmemorable game which Fischer like any other player was bound to play from time to time--just more or less routine chess...” and pointed out that though the game was drawn after Sanches sealed 41. Nd3, the game would appear to be anything but drawn with 41. Qh3. Additionally white has fantastic bishops and an advanced passer...why did Sanches agree to the draw against the 16 year old Bobby? A few continuations are given after 41. Nd3: 41...h3, when white now appears to be in trouble because of 42. Kxh3?? or 42. Qxh3?? and then 42...Rh8, while 42. gxh3? gives black strong initiative after 42... Nh4. A different move 42. Bc5 he claims is interesting, and 42. Qf5 leads to a material loss for white and a win for black so why did Bobby agree to a draw? Because it’s not exactly a win for black after 42. Qf5 hxg2 43. Qxg5 Rh8+ 44. Kxg2 Rh5...when 45. Qxh5 Nxh5 is not so winning for black because after 46. Bf2 white can infiltrate with his rook along the file. The question remains: why was the game drawn? Afraid of young Bobby? Anyway, these routine games are often some great places to learn technique. thoughts? non?
Nov-24-04  drukenknight: It is also interesting because Bobby never seemed to be quite comfortable in this defense and was searching for something else to meet the top players with. Geller destroyed it at Havana. He turned to Grunfeld and Nimzo Indian.
Nov-24-04  drukenknight: Here is the Geller game from Havana 1965, Bobby's cable tournament, as it were:

Nov-25-04  OverDjinn: You're saying he was never comfortable in a KID? Isn't that the defense he is most famous for? A puzzle...
Aug-18-08  RandomVisitor: After 41.Nd3 h3 (forced) 42.Bf2! Black might have trouble drawing:

Jan-19-17  RookFile: I think we know why Fischer agreed to a draw. If his opponent finds the right moves he is in danger of losing. Evidently Sanchez didn't fully realize how good his position was.

This was not so easy, but the maneuvering is known, since Euwe wrote about it. Now Black can't play 65... Qg7 because of 66. Rd3
