Kibitzer's Corner
Jan-24-09  rwbean: "Recent analysis, with a more powerful chess computer (Deep Blue Jr), showed that Deep Thought could have played a combination and possibly won the game outright on move seventeen. (Ne5 with the idea of Nf3 giving up the c pawn for a strong attack, possibly with Bd3 later." -- "Behind Deep Blue", p84

Ne5 is the first and only move that Rybka 3 considers (17 ply, eval +1.20, pv 17... Ne5 18. b3 Nf3+ 19. Bxf3)

"On move twenty-six, Bent made a slight error ... In reality, the bad move was the next one [move 27]". -- p85

Rybka prefers 26... Nc3 (15 ply, eval +0.37)

  perfidious: A few months before this game, I had the dubious pleasure of facing the monster at the US Open; it was the latter of the two times I've opened 1.g3 in my life. After losing, I was a little put out, as I felt I could have played better-then the wretch destroyed Igor Ivanov in twenty-odd moves in the next round !!

  Landman: As I recall, this was the first time a GM lost to a computer under tournament conditions.
Oct-16-10  ttr2121: You are correct, Landman. It was at a Swiss in Santa Monica, Thanksgiving weekend 88. Tal was also a guest of the tournament. I was there and remember well the buzz that went up when Larsen got smoked.
Feb-05-15  TheBish: <ttr2121> It was not in Santa Monica, it was Long Beach! (It is spelled out five times on this page, if you look!)

I was at that tournament, and actually had breakfast at the hotel restaurant just a table away from the Great Dane himself! Maybe right before he lost this game, I don't remember for sure which day that was but I think it was early on. I also had the great pleasure of watching Tal play in the blitz tournament. That was a treat! His games were amazing, sacrifices left and right for the attack, and pretty much making his pieces dance!

Jan-11-17  smcracraft: Hi -- I was the operator of Deep Thought II at Long Beach (it was physically at CMU outside of Pittsburgh) via a phone link arranged by the sponsor Les Crane of Software Toolworks. It would have been great to see Tal demolish DT with his pure-art sacs but that was not to be. Tal did come over and check it out journalistically. Quite a raven-eyed one. Tal was, by far, my favorite player. Larsen and the other GM's, IM's and FM's were all very gracious in their games with DT. Fun event! Browne is to be congratulated for his win and McCambridge for his draw. --Stuart
