Analysis by Rybka 3 1-cpu 32-bit :

1. ² (0.30): 19.Nxd7 Rxd7 20.Kf2 f6 21.Rd2 Kf7 22.b3 g6 23.Rcd1 Rfd8 24.a3 b6 25.b4 Ke7 26.Ke3

2. = (0.14): 19.Na4 Bxa4 20.Bxa4 Nc5 21.Bc2 e5 22.Rd5 Ne6 23.Rcd1 Nd4 24.Bb3 g6 25.f4 b6 26.Kf2 Kg7 27.Ba4 f6

Oct-06-09  tonsillolith: Here is what Rybka thinks the evaluation is after White plays Nd5:

1. = (0.17): 19...Bxd5 20.exd5 e5 21.b4 b6 22.g4 g6 23.Kf2 f6 24.h4 Rc8 25.Ba4 Rf7 26.Ke3 Nb8 27.h5

Nov-02-09  AnalyzeThis: Unless it's a forced win, it's really just a question of style. I think that Fischer figured the bishop would be better than the knight here and this guided his play.

  HeMateMe: you get the feeling that the game is over after the 20th move, when white has a majority on the Queenside.
Nov-02-09  jovack: to HeMateMe:

no you really shouldn't get that feeling because the game is far from over at that point.

Premium Chessgames Member
  HeMateMe: <jovack:> But you don't understand. According to biographer Frank Brady Fischer would BECOME that passed pawn, he would will it to the 8th rank, as surely as he would continue to breath. That willpower seemed keenly on display here.
Nov-02-09  FHBradley: "Rossetto stoned"; very nice, if, for someone, possibly slightly politically incorrect.
Nov-02-09  tonsillolith: <FHBradley>, you forgot to put commas after the words "possibly" and "slightly".

Worth watching.

  kevin86: White will win as black is void of any productive moves. The win WILL be slow and painful-so black decided to relieve himself of the pain by dropping his flag.
Premium Chessgames Member
  YouRang: Fascinating how Fischer's bishop on b3 has black completely bottled up. Neither the knight nor the king dare move.

BTW, backsliding through this game with my computer, I noticed that Fischer played with practical perfection from move 17 forward.

Obviously he was playing with illicit assistance from Rybka.

Premium Chessgames Member
  Eyal: <The win WILL be slow and painful>

It might actually be quick and painful, since Black has soon to drop at least a piece - if the king moves away from the knight, 38.Rb8! Rxc7 39.Rxf8; if the knight moves away from f8, then 38.Be6 wins immediately; if the rook moves along the back rank, same goes for 38.c8=Q+.

19.Nd5! is a very resourceful move - perhaps with best play by Black it shouldn't lead to a win, but it creates problems for him and leads to imbalances in the position that might be exploited. On the other hand, the computer line 19.Nxd7 Rxd7 20.Kf2 f6 21.Rd2 Kf7 22.b3 g6 23.Rcd1 Rfd8 24.a3 b6 25.b4 Ke7 26.Ke3, mentioned above as Rybka's top choice, doesn't seem to lead White anywhere, even if it's evaluated as giving him a small advantage.

In MSMG, Fischer points to 23...f5 as the decisive mistake, recommending instead 23...a5 first (24.a3 f5; or 24.Bxd7 Rxd7 25.bxa5 bxa5 26.c5 dxc5 27.Rxc5 a4) - and making the important comment that Black shouldn't allow the c5 break without first forcing White to make the concession of exchanging the bishop for the knight.

Premium Chessgames Member
  Once: An astonishing final position - nothing can move. Any pawn move just allows it to be gobbled up. Any knight move lets the Bb3 get to e6. Any sensible rook move is answered by the discovered check c8=Q+. If the king moves, white plays Rb8 and the rook is pinned against the now unprotected knight.

What's left? Resignation. Genius.

Nov-02-09  WhiteRook48: great zugzwang
Nov-02-09  chillowack: <FHBradley: "Rossetto stoned"; very nice, if, for someone, possibly slightly politically incorrect.> Not as I understand it. The reference is to the famous "Rosetta Stone," an ancient stone tablet; and the word "stoned" refers, not to the smoking of marijuana, but rather to the process of being killed with rocks.

I could be wrong though: maybe the punster did mean smoking pot.

Fischer vs H Rossetto, 1959 19 Nb6-d5! intends .. e6xNd5 e4xd5 harvesting trapped c6-bishop

Premium Chessgames Member
  TheFocus: This is game 5 in Fischer's <My 60 Memorable Games>.
Premium Chessgames Member
  maxi: Yeah, <TheFocus>! I am going to go over Bobby's notes.
Premium Chessgames Member
  maxi: In My 60 Memorable Games Fischer makes the comment to move 21.b4: “Playing for the big breakthrough on c5”. Objectively speaking Fischer does not have an advantage. So, what does he mean?

In a position such as this the advantage of having Bishop against Knight is minimal. It is possible for White to get a passed Pawn on the Queenside and that certainly is a threat to keep in mind, but Black has another breakthrough available to him by playing f5 and e4, so he can still hold his own. But a chess player knows that, in a position such as this one, the White Bishop can be very powerful in either a4 or b3. Also, any slip from Black and the White Rooks penetrate the Queenside causing havoc. So Fischer knew there existed practical chances.

The game went on 21. b4 g6 22. Ba4 b6. It would be better here to activate the Black knight with 22…Nf6. The problem with 22…b6 is that it weakens the Black a6 Pawn. Fischer played right away 23.Rd3 to take advantage of this mistake. But the position is still far from lost. Now Black plays 23...f5, with the idea of carrying through his breakthrough at e4, but it was essential to eliminate his weak a-Pawn, as Fischer writes, with 23…a5. Fischer now plays 24.Ra3 threatening to win the a-Pawn, and Black answers 24…Nb8. This is the move that loses the game; at least to save it from now on seems very difficult to me. The Black Knight is trapped on b8 and Zugswang begins to rear its ugly head.

Black still could play 24…a5 instead. Fischer gives the line 25.bxa bxa 26.Bf6 Nc5 27.Rxa5 and adds that “White should win.” I went over this position with Houdini and Black has drawing resources. The Black Knight is in a very active post and now Black’s dreamed-of breakthrough …e4 can actually be played. It is still a fight.
