Aug-30-04  Knight13: Nice long game.
Aug-09-05  bishopmate: Deep Blue made some very awkward moves in the endgame...
Jul-05-06  Fast Gun: Where exactly did Deep Blue go wrong? A fine effort from GK to outplay the IBM monster calculator. Clearly GK realised he would have to change his style of play if he was to defeat Deep Blue after he was outplayed in the tactial minefield of the first game of this match:
Jul-05-06  RookFile: Kasparov was essentially playing the Gruenfeld defense with a move in hand in the opening.
Nov-02-06  Pi Guy: From moves 33 to 47, it seemed that all Deep Blue wanted to do was to exchange queens, but from moves 51 on, it seemed that Deep Blue was avoiding the exchange of queens. Can anyone make sense of this?
Jan-06-07  viv001: Endgame was horrille.
Aug-30-07  KasparovFan123: I think that deep blue made a number of simple mistakes that cost it the game. The biggest one that i saw in the endgame was the ep when Kasparov played f4. that is because it isolated the d3 pawn but more importantly it severely weakened the f5 pawn. Kasparov then plays f4 after the exchange to keep the f5 pawn on a light square to make it an easy capture for the white queen and the light squared bishop. If the queens were exchanged between moves 33 to 47 then the game would have probably ended in a draw since it was materially even and more importantly opposite colored bishops were on the board. After the ep blunder however black could not exchange queens since the f5 pawn was doomed to fall(with the black king so far away) and white's 3 connected kingside pawns would easily decide the game. Deep Blue realized that it only had a chance to draw the game if the queens were on the board, but only a slight chance at best. Hence the resignation 1 move after the queens were exchanged.
Dec-10-07  D.Observer: Kasparov did not try 43. Qb7+.

72 ♗b5 1-0

72... ♔d6 black ♔ enters the "magical square" of ♙h4

73 h5 ♔e7 74 h6 ♔f6 75 h7 ♔g7

♙h was able to reach quietly h7 thanks to ♙f4 blocking black ♗e3

♘ow white ♙h7 is attacked by black ♔g7

76 ♗d3 white ♗d3 protects ♙h7 and on the other hand blocks the progression of black ♙d4 which might be wanting to queen !

♗d3 blocking black ♙d4 "frees" white ♔ to help his queening ♙

♙d4 makes it difficult for black ♗e3 to control the queening square h8 !

♙d4 makes ♗e3 a "wrong" ♗

If ♗e3 wants to control h8 to prevent ♙h7 from queening, it needs no less than 4 moves !

76... ♗d2 idea : ♗d2-b4-e7-f6 to control h8 !

77 ♔e2 ♗b4 78 ♔f3 ♗e7 79 ♔e4 ♗f6 80 ♔f5

♘ow white ♔ is in touch with black ♗...

  lost in space: <gambitfan>, as white I would play Ke2, Kf3 and than g3-g4. The 3 pawns can not be stopped.

Really? I thought this was a tough game, and the computer defended well. It wasn't obvious to me that Kasparov was going to win.

Sep-30-09  peteor: I don't like deep blue's 21. Qc8 ... is Rd8 not the better move?
Premium Chessgames Member
  An Englishman: Good Evening: I once played White in a casual game where my e-pawn did not move during the entire affair (45 moves). Here, White's e-pawn doesn't move until 61.exf3. Any game at least as long as this where the e-pawn doesn't move at all?
Sep-30-09  AnalyzeThis: <peteor: I don't like deep blue's 21. Qc8 ... is Rd8 not the better move?>

Well, Kasparov can put the queen on f5, the bishop on e4, and h7 is going to drop. The computer must have felt this needed to be prevented.

Yes, it seems strange as this isn't how computers "think" usually. Some would say (Kasparov included) that Deep Blue had some human assistance during this game. The desire to exchange queens / keep queens on the board is a very human approach to chess.

Sep-30-09  engineerX: <Garech:Some would say (Kasparov included) that Deep Blue had some human assistance during this game.>

I have not read such a claim by Kasparov and I don't think he has made one. You should provide a link or a quote, else it is only _your_ opinion.

I think DB played the inferior endgame quite naturally for a computer.

Sep-30-09  Steven87: I'd asked one of my comp sci profs about constructing a chess ai not 5 days ago, and he'd then mentioned Kasparov's claims as well.

That not withstanding, computers will always do exactly what their programmers tell them too, and if a position can be evaluated as being favourable with or without queens when the opposite is currently true, it's entirely plausible for Deep Blue to react the way it did.

Sep-30-09  tivrfoa: great pun, and game =)
Sep-30-09  Big Easy: Kaspy plays with such precision in the endgame. He avoids the queen exchange and then wins a pawn, then a second, and then forces a queen exchange. Very nice.
Premium Chessgames Member
  kevin86: It looks like Blue blew a gasket. lol
Sep-30-09  venkatesh920: <Pi Guy> Deep Blue wanted to exchange queens earlier so that it would be easier to draw... but later it didn't want to because exchanging queens would lead to defeat as GK has 3 pawns n a bishop whereas DB has only a pawn n a bishop..
Sep-30-09  WhiteRook48: basically by 70 Qd8+ black is lost
Sep-30-09  CoryLetain: Fischer claims they turned down the strength of the machine after Deep Blue romped GK in the first game.
Premium Chessgames Member
  Eisenheim: i'm impressed with 19 b4. what a great non-obvious diversion. and <CoryLetain> can we ever take any of Fischer's rantings seriously?
