35.Rxd3 does leave a near even game - black's a shade better, but a draw is probably correct. As <goldenbear> pointed out though, the position is not to Larsen's liking. Nonetheless, it's probably white's best chance to stay in the game.
White is in real trouble after 38.f3?! perhaps missing the strength of the reply 38...d4! Instead, 38.Rb7+ Kf6 39.Rd7 gives white some practical chances. However, after 39...Be4! the black king is released. White can try 40.f4 but then 40...Bf3! keeps the game in black's hands. The critical line appears to be 41.Rd6+ Kf7 42.Re5! Re8!
Meanwhile, 38.f4?! is also answered by 38...d4! 39.Rc1 Rd8 and black wins similarly to the game.
|Mar-25-06|| ||larsenfan: This game is annotated in Secrets of chess defence, by Mihail Marin, a very nice book. There is a whole chapter devoted to ex change sacrifices, and of course, several examples from Petrosian's games. A good reference if you like this subject.|
|Mar-25-06|| ||keypusher: Playing over the game I kept wondering why Petrosian didn't take White's pawn on d4.... After 47 Rd8+ Kc4 I finally saw why!|
|Mar-25-06|| ||ray keene: i had the privilege of watching this game live-it was a needle game for petrosian since he had just lost twice to bent at the piatigorsky cup- a third loss wd have more or less finished his reputation as champion-many people write that petrosians last good result as world champion was his title defence v spassky in 1966-however they overlook his gold medals both team and individual on top board for the ussr in the 1966 and 1968 olympiads-where-taking both into account- he finished ahead of fischer portisch gligoric hort uhlmann najdorf reshevsky larsen and many others|
|Mar-25-06|| ||Mating Net: <ray keene> Fantastic bit of information, thanks for sharing it with us.|
Do you recall your reaction to Petrosian's 14...Rxe5! by any chance?
|Jun-16-06|| ||wharfrat: I think Larsen avoided 35.Rd3 because he was convinced it was dead lost for White. After 35...Bd3; 36.Qd3, Rd8, Black will first establish a passed pawn and force White to blockade it. Black will then combine the threat of pushing the passer with attacking the other weaknesses in White's position (a4, h3, f2, the 1st rank, the light squares around White's king). White has absolutely no counterplay and he won't be able to cover everything. For a very informative treatment of this type of position, check out the section on Alekhine in Mihail Marin's "Learn from the Legends."|
|Jun-16-06|| ||ray keene: sorry i missed the query for a while-this was the game of the olympiad-the tension was terrific and when petrosian sacrificed on e5--which i watched- it was not a big surprise because he had sacrficed the exchange so often against spassky in their match from 1966. btw i think if white re-sacs on d3 it must really be a draw.black can play but white shd hold. very interesting also is to meet 21---Ng4 with 22 Bxa7!? I ANALYSE THIS GAME IN TREMENDOUS DEPTH IN MY FORTHCOMING BATSFORD BOOK PETROSIAN AGAINST THE ELITE.|
|Jun-16-06|| ||RookFile: Beautiful game by Petrosian. He put up a score of 9 wins to 4 against Larsen in his career.|
|Jun-16-06|| ||Boomie: A Petrosianesque answer to 35. Rxd3 is Be4. The threat of white square domination is too compelling.|

|Aug-06-06|| ||notyetagm: With 47 ♖d8+ ♔c4 48 ♖c8+ ♔d3 Black uses the White d4-pawn to shield his king from the White rook checks. |
This idea is called <The Sheltering Pawn> in one of Chernev's books.

So how is your book coming along, GM Keene?
|Aug-06-06|| ||positionalgenius: <raykeene>I recently read your book about the 1990 kasparov-karpov title match,"Clash of the Titans".It was very good.Where can I find other WCC books by you?|
|Apr-06-07|| ||stanleys: Well I will not call this sacrifice "fantastic"
Boleslavsky thinks that "this is the best practical chance for black".However after 16.f3 white seems to have an advantage.Another error was exchanging the dark-squared bishop

Since GM Keene apparently has not visited this page for some months, I will note on his behalf that his book on Petrosian has been available for purchase at least since late January 2007.
|Aug-03-07|| ||bettermove: Weird game?! What a fascinating style Petrosian played this with.Err... how did he play like this? His chess playing style should come with a health warning...quite extraordinary!|
|Jul-09-08|| ||Everett: I think a well timed c4 by white gets him out of trouble. On move 35 for instance.|
|Jul-09-08|| ||paul1959: <Everett> Maybe , but I think that Larsen was not thinking of saving the game at that point but win it. Otherwise he had no reason to exchange Queens. He was the ever-optimist|
|Jul-10-08|| ||arsen387: No one ever played exchange sacs like it did Petrosian. Sac the exchenge on move 14 to win the game on move 48. What a profound understanding of chess he had! Amazing|
|Jul-10-08|| ||HannibalSchlecter: Seems like Petrosian doesn't sac unless he is more or less "forced" to out of necessity rather than an adventuresome mindset.|
|Jul-10-08|| ||Everett: Seriously, Petrosian sacs the exchange of 14 because he was about to get crushed. Says more about his uneven opening prep (and Larsen's strong opening play) than any advanced designs of the sac.|
|Mar-10-12|| ||LoveThatJoker: <Everett> I'm a huge Petrosian fan. I agree that the exchange sac on move 14 occured because Petrosian's opening prep was a bit left-field in this game.|
That being said, it is amazing to see how he creates and builds upon coordination of his pieces after the exchange sac occurs (the exchange sac itself serving to commence this harmonizing phase).
Another defensive gem that is akin to this one is Fischer vs W Wagenhals, 1964 which was brought to my attention by <Memethecat>.
|Mar-10-12|| ||ughaibu: This one's fun: Najdorf vs P Trifunovic, 1949|
|Nov-07-13|| ||hyperactivemodernist: Masterful play from Petrosian. He could afford to go down in material with the exchange sacrifice because of his expert pawn play. He leaves no weaknesses for Larsen to attack with his rooks.|
|Jun-27-16|| ||Zhbugnoimt: Almost everyone here is judging the opening by the result of the game and is making themselves look foolish. Petrosian was in huge trouble at move 14, and saced the exchange to get practical chances. Had Komodo been playing White...
Point is, Petrosian was in very bad shape out of the opening and beat Larsen only because Larsen played very poorly from there on out.|
|Nov-26-16|| ||ray keene: I refer to my comments below. I watched this game and annotated it in depth in my book on Petrosian.|
