| Aug-18-13 | | RookFile: I think it's fair to say that Fischer made a misstep in the opening and should have been punished. He was in some trouble and showed resourceful defense. |

| Sep-03-13 | | Howard: Geller later found a likely improvement in 13.Bf4, with the idea of keeping the bishop pair. He played it twice against Timman in 1975, winning one and drawing the other. |
|
Sep-03-13
 | | perfidious: There was also Geller vs Hecht, 1973. |
|
| May-05-14 | | Everett: Reading the above analysis and knowing the players, it makes perfect sense that Kasparov would try to make the sacrificial 18.Nd5 work, whereas I could see Karpov playing 18.Qe1 and tightening the screws. The man was never in a rush. |
|
| Jun-03-14 | | Howard: It was believed for awhile that 24.Rc7 would have given good winning chances, and the late Larry Evans once discussed this move in his monthly CL column back in 1988. But, as I recall, Kasparov's MGP indicated that Black had a defense---don't recall it though. |
|
| Jun-04-14 | | Howard: By the way, I just looked at Timman's analysis of the game in his classic Art of Chess Analysis, and he mentions that rather than play 20.Bf7+, White should first have interposed 20.exd5. Any comments from Uncle Fritz or his relatives ? |
|
| Jun-04-14 | | RookFile: See comments from above on August 23. |
|
| Nov-29-15 | | Howard: I recall a game from Informant many years later which followed this game up until Move 23, and then White varied with the much-recommended 24.Rc7. Does anyone know what game that might have been ? |
|
| Nov-29-15 | | Chessdreamer: <Howard> You are right. In the game Van der Gracht-Prins, corr. 1986 (Inf. 42/132) the actual move order was 7.c4 Nb6 8.h3 Bh5. The rest of the game:
24.Rc7 Nxd4 25.Rff7 Be3+ 26.Kh1 Bh6 27.g4 Rf8 28.Rfd7 Nf3 29.exd5 exd5 30.e6 Re8 31.Rxa7 d4 32.c6 1-0. |
|
| Dec-01-15 | | Howard: Now, how did you look that up?! |
|
| Dec-04-15 | | Howard: Well, that game from 1986 isn't on this website. |
|
| Dec-04-15 | | Howard: By the way, could anyone supply some analysis analysis on 24.Rc7 ? That was apparently Spassky's best move though Kasparov's MGP says it wouldn't have won....or could Stockfish and/or Komodo refute that allegation ? Thanks much ! |
|
| Dec-04-15 | | john barleycorn: <Howard> please, find Timman's analysis here
<22.Qd2 there is nothing better
22.Rc7 Na6 23.Rc6 Nb4 24. Rxe6 de4 leads to a sharp position in which Black would have the better chances.> http://www.chessdownload.files.word... |
|
| Dec-05-15 | | Howard: Oh, I have the book---the second edition, in fact. But I thought, perhaps, that Mr. Stockfish or his cousin Mr. Komodo might have some suggestions. |
|
| Sep-02-17 | | The Kings Domain: One of the most compelling and instructive draws of the game. If all or at least most draws were like this no one would be complaining of grandmaster draws. |
|
| Sep-02-17 | | Petrosianic: <The Kings Domain>: Yes, it's non-specifically notable in ways we can't explain. Good observation. That's what the discussion was missing. |
|
| Sep-05-17 | | Howard: Andy Soltis referred to this game back in a 1996 (approx) column as one of the most heavily analyzed draws of the last thirty years. Of course, we didn't have (very strong) computers back then. Personally, I've always had this nagging feeling that Spassky just might have had a forced win, or at least something pretty close. |
|
| Sep-12-18 | | CharlesSullivan: <Howard> Even using Stockfish 9 and a 16-core AMD Threadripper, my conclusions are not much different from those of Kasparov[2004] or Timman[2009] or (<RandomVisitor[2013]> or <Hesam7[2013]>.
1. I agree with Kasparov that Petrosian's 14...Nc6 leads to an equal game. (Timman thought White would still have the advantage.) After playing 14...b6, Fischer rapidly got into a dire situation.
2. Better than Spassky's 18.Nxd5 would have been Olafsson's suggested improvement 18.Qe1. After an 85-hour search (depth=58), Stockfish confirms Timman's opinion that best for Black is 18...Qd8 <+1.05>. Black has to be willing to give up a knight for 2 pawns in the main variations, but he seems to be able to survive a precarious endgame because White is left with bishops of opposite color and/or insufficient material to make a breakthrough:
(A) 18.Qe1 Qd8 19.Be2 Nd7 <+1.05> 20.exd5 cxd5 21.Kh1 a6 22.Bd3 g6 23.Bc2 Rc8 24.Rf3 Qa5 25.Bb3 Nxc5 26.dxc5 Bxc5 27.Qh4 Qb4 28.Qxb4 Bxb4 29.Na4 Bd2 30.Raf1 Rc1 31.Kg1 Rc7 32.Nb2 Bc3 33.Nd3 Bd4+ 34.Kh1 a5 35.h4 Kg7 36.g3 h6 37.Kg2 Rfc8:

(B) 18.Qe1 Qd8 19.Qe2 g6 20.Rab1 Nd7 21.exd5 cxd5 22.Kh1 Rb8 23.Nb5 <+1.29> Nxc5 24.dxc5 Bxc5 25.Rbc1 Qb6 26.a4 a6 27.Nd6 Bxd6 28.exd6 Qxd6 29.Qd3 Rb4 30.a5 Ra4 31.Qd2 Ra3 32.Rb1 d4 33.Rb7 Qe5 34.Bg4 Qd5 35.Qb4 Ra2 36.Bf3 Qe5 37.Rd1 d3 38.Rxd3 Ra1+ 39.Bd1 h5 40.Qd2 Rxa5 41.Rdd7 Rc5 42.Bc2 Qa1+ 43.Rb1 Qc3 44.Qxc3 Rxc3 45.Bd3 Rfc8 46.Rbb7 Rc1+ 47.Kh2 Rd1 48.Bxa6 Rxd7 49.Rxd7 Ra8:

3. I completely agree with <Hesam7> that Kasparov's suggested improvement 19.Qd3 exd5 20.exd5 Na6 21.d6 Nxc5 22.dxc5 Qxc5+ 23.Kh1 runs into 23...Rae8 (mentioned by Karsten Müller in Bobby Fischer [2009]) and White's winning chances evaporate.
4. After 20.exd5 exd5 21.Bxf7+ Rxf7 22.Rxf7, Kasparov called 22...Qc3 "the most accurate" move, but 23.Rb1
click for larger view
is rated at +2.29 and wins (23...Nc6 24.Rbb7 and White dominates) -- Black cannot take the rook: 23...Kxf7 24.Qh5+ Kf8 25.Rf1+ Bf6 26.exf6 Qxd4+ 27.Kh1 gxf6 28.Qxh7 wins (28...Nc6 29.Qh8+ Kf7 30.Qxa8 Qxc5 31.Qh8 Qe7 32.Qh7+ Ke6 33.Qf5+ Kf7 34.Qxd5+, etc., or 28...a5 29.Re1 Qxc5 30.Qh8+ Kf7 31.Qe8+ Kg7 32.Re7+, etc.).
Instead, Black plays 22...Qd2 <+0.79> 23.Rc7 Na6 24.Rd7 Be3+ 25.Kh1 Qxd4 26.Rxd5 Qxd1+ 27.Raxd1 Rf8 28.c6 Bb6 29.a4 Re8 30.a5 Bc7 31.Re1 Re7 32.e6 Kf8 33.Rd7 Ke8 <+0.60> 34.Rf1 Rxe6 35.Rxg7 h6:

and Black can hold this position, it appears.
5. As others have pointed out, 24.Rc7 is met by 24...dxe4 (Olafsson) 25.Rxc6 e3 26.Rxe6 e2 27.Kf2 exf1=Q+ 28.Kxf1 Rd8 29.Rd6 Rxd6 30.exd6 Kf7 31.Ke2 Ba5:

and in this case, Black's extra bishop can hold against White's three extra pawns. |
|
| Jun-08-19 | | Howard: Has the final word been uttered yet on 19.Qd3 ? Kasparov says in OMGP that it would have been stronger than the move that Spassky actually played, and some sources claim that it may have won. Would it ?! |
|
| Aug-16-19 | | Robyn Hode: This line in Alkehine's is rarely played nowadays. Much more common is 4...dxe5 5 Nxe5 g6. |
