| Jun-21-14 | | Marmot PFL: <thegoodanarchist: Must be nice to defeat the reigning world champion, even if it is just with the White pieces.. :)> Larsen beat Petrosian twice in this event, once with each color. Petrosian's results as WC were not very good, outside of Olympiads and his first match vs Spassky. |

 | | perfidious: While the statement on Petrosian's performance overall as reigning champion is true, it is no different than things were with his predecessors: Alekhine was the previous champion to post consistently excellent results as titleholder, and it would only be with Karpov's ascent to the throne that the world would see another. |

 | | FSR: <Marmot PFL> True, although he did tie for first with Keres at the First Piatigorsky Cup (1963) shortly after becoming champion. |
|
| Jun-21-14 | | Petrosianic: <Larsen beat Petrosian twice in this event, once with each color. Petrosian's results as WC were not very good, outside of Olympiads and his first match vs Spassky.> Not very good by Karpov/Kasparov/Carlsen standards. We've gotten spoiled lately by having 3 of the last 5 champions be dominating ones. But throughout history, that's been the exception rather than the rule. Of the non-dominating champions, Petrosian's results were actually better than most. |
|
| Jun-21-14 | | Moszkowski012273: 28...Be5 was a wee bit better. |
|
| Jun-21-14 | | gars: Petrosian lost a third game in this tournament, this time against Portisch (White), a King's Indian Defense which lasted thirty-two moves. |

| Jun-21-14 | | Rookiepawn: Hey, thanks to all who replied to my useless idea. They all proved me wrong, but <Jimfromprovidence>'s variant is the most elegant. "Untouchable?, we'll see that" was my first thought... And yes, it is untouchable so the rook can still move on the rank. CG rocks! |

 | | Jonathan Sarfati: Don't forget that Petrosyan was the first world champ actually to win a world championship match while champ (Petrosian - Spassky World Championship Match (1966)) since Alekhine - Bogoljubov World Championship Rematch (1934) |

 | | Breunor: IS 20 B x c5 better than e5? I think it wins a queen for a rook and bishop, but that may not be better than the game. 20 B x c5 P x c5 21 Nf6ch B x f6 22 R x d8 Rf x d8.
Is there a better line for white here? |
|
| Jun-22-14 | | M.Hassan: "Very Difficult"
White to play 25.?
White is a pawn down and has a Bishop for a Knight.
The open h file is tempting:
25.Qxg6 fxg6
26.Bxe6+
A)
26.........Kh7
27.Rh3+ Bh6
28.Bxh6 threatening next Bf8#
28.........Rf7
29.Bxf7 Qd7
30.Bf8+ Qxh3
31.gxh3 Rxf8
32.Be6
White is stronger and should win.
B)
26..........Rf7
27.Bxf7+ Kh7
28.Rh3+ Bh6
And the above line can be repeated.
Time to check
=============
My lines are way different |

 | | Honza Cervenka: <Alanx: Stop seeing the end. 20.-Bxc5! would have finished the match earlier.> Well, it is not so simple. After 20.Bxc5 dxc5 21.Nf6+?! (21.Qxc5 is probably better here) 21...Bxf6 22.Rxd8 Raxd8 (diagram) black can be satisfied. 
click for larger view White nominal material advantage (Queen against Rook and Bishop) is compensated by powerful Bishop pair and firm control of d-file. The game can continue with 23.Qe2 (black was threatening Bd4) 23...Be5 24.b3 (24.Rd1 drops the Pawn on b2) 24...Rd4 25.Bf3 Rfd8 and it is already black who can hope in advantage. Of course, both players were well aware of that, Petrosian intended to sac his Queen in this way and Larsen was absolutely right to decline this offer. |
|
| Nov-27-14 | | thegoodanarchist: The Black Queen never moved. |
|
| Nov-04-16 | | spazzky: 20.Bxc5 can also be met with ...BxNd5 also, no? Then white's beautiful knight is gone, and with it the attack |
|
| Jan-26-17 | | Albion 1959: To Chrisowen - Is that Nadsat as used in The Clockwork Orange? |
|
| Mar-17-17 | | clement41: The kind of queen sac that's risky because heavily calc-based. one calc mistake and it's over |
|
| Sep-14-17 | | Toribio3: Larsen is unorthodox player. He prefers less analysed variation on various openings. Element of surprise is his most priority. |
|
| Dec-05-18 | | fishcake: <spazzky: 20.Bxc5 can also be met with ...BxNd5 also, no? Then white's beautiful knight is gone, and with it the attack >
20. ... BxN doesn't seem to work because of 21. RxN |
|
| Oct-27-20 | | Granny O Doul: Regarding the line with 20. Bxc5 and 21. Nf6+, Larsen's comment was "this White can never win, and he may even lose". |

| | perfidious: Any fairly competent player would see that the position from the diagram posted by <Honza Cervenka> offers only Black chances of playing for an advantage, despite his material deficit. |
|
| Jan-11-21 | | ZoneChess: Opening the H-file and the subsequent rook lift always seems to be the key to beating the dragon at top level. |

Yes, obviously.
Weird, interesting SF point: the engine prefers 21....exf6! 22.Rxd8 Raxd8 and Black threatens ...f5. After 23.Bf3 Rfe8 24.Re1 Re5 the engine score is about -0.76. |
