Apr-08-08  Ulhumbrus: <Knight13: 39...Bd8 and then bring the h-rook to c7 by Rh7-c7 and hold off. Might be good.> This defends the b6 pawn, and so frees the Ra6 from having to defend it. However on 39...Bd8 40 e4 attacks the d5 pawn a third time, and the d5 pawn is pinned against the f7 pawn.
Apr-08-08  Knight13: Then I guess that means play 40...Bd8 instead, and not the Rh7-c7 thing as it would hang the b pawn.
Apr-12-08  Ulhumbrus: <Knight13: Then I guess that means play 40...Bd8 instead, and not the Rh7-c7 thing as it would hang the b pawn.> There is however another threat as well, that of Nxd5, as the c6 pawn is pinned to the Rook on c8 and so cannot recapture on d5.
Aug-15-09  Davolni: This game is I believe the last game Petrosian won as a champion.

Interesting and nice game!

  perfidious: <Ulhumbrus: An alternative to 23...h5 is 23...f5 playing for the thrust ....f4>

On first glance, this seems reasonable.

In <scrambler>'s link, Geller gives 23....Qe6. It's hard for Black to do anything active here without weakening his position, which was very much in line with Petrosian's intentions.

Jun-16-11  msoewulff: interesting to watch white gradually invade black's territory.
Jul-18-12  Ulhumbrus: <ray keene: the main line goes like this-50...kh8 51nxf7+ kg7 52 rxf8 qd2+ 53 kh3 qd1 54 rg8+ kxg8 55nh6+ !! kg7 56 qg8+ and black is mated. the whole of the second session followed petrosians analysis. > One point of 50...Kh8 is that the capture 51 Qxf7 will not come with check, and from f7 the queen covers no longer the square e2, and this gives Black time to play 51...Qe2+ with a draw by perpetual check. So after Black has thrown this spoke into what would be otherwise a comparatively "simpler" win White has to settle for the comparatively more complicated win beginning with the check 51 Nxf7+
Feb-21-13  Garech: Another great fighting game between the Russian giants! Amazing to see them play in such a way, given the stakes. Petrosian was trailing at this point in the match; it must have been a sweet - albeit shortlived - joy that triumph brought.

-Garech

Dec-08-13  Ulhumbrus: Perhaps this was the best game of the two matches. Petrosian made use of combinations to help take the game towards a state where Spassky could no longer cover his weaknesses and had to start a combinative fight, a combinative fight which ended in victory for Petrosian. This looks like an example of what Euwe called <Combinations for strategic ends>
Dec-12-13  Ulhumbrus: <scrambler: This game with annotation:

http://www.ez-net.com/~mephisto/Car...> Thx. I have taken a look at it and it is well worth the look. The annotations are quite instructive. One of the Soviet analysts- possibly Geller - points out a combination which Petrosian missed just before the time control at moves 39 and 40. Instead of 39 Nf4 Petrosian can win at once by 39 Nxc6! Rxc6 40 Rxc6 Nxc6 41 Qb5! Nb8 42 Rc8+ Kg7 43 Rxb8! Qxb8 44 Qxa6 and at move 40 instead of 40 Ne5-d3 Petrosian can win by 40 Nxc6! Rxc6 41 Rxc6 Nxc6 42 Qb5! Nb8 43 Rc8+ Kg7 44 Rxb8! Qxb8 45 Qxa6.

Oct-11-14  Ulhumbrus: Petrosian, as did Nimzowitsch, employs combinations to pursue strategic ends
Mar-18-16  lemaire90: That bad rook ! Hanging on c8, overloaded on f8. Majestic performance by Tigran.
Mar-18-16  The Kings Domain: Solid and steady play by both sides in this fine game.

Don't have a clue about this game title

  kevin86: If black takes the rook, he will be mated in two.
Mar-18-16  Howard: This was Game 20 of the match, and it was also Petrosian's last win.

  Gilmoy: <46.Qc4> is an amazing coda with multi-tasking threats: (1) daintily steps out of the <mutual threat> chain; (2) pins c6 to Rc8; but even that's a mere decoy for (3) a hidden-double on f7.

He must have seen all of that before <41.Qxb6> :)

  morfishine: <weary willy> From what I can tell, your explanation is much more clever and witty than the actual game title, which IMHO, would best serve mankind the sooner it becomes extinct

  paavoh: My guess is that the title may have originated from this note <Davolni: This game is I believe the last game Petrosian won as a champion.>, so T-Rex is sort of fitting. At least it is not entirely based on the last name, as they seem to be these days...
Oct-03-18  Petrosianic: <Ulhumbrus: Perhaps this was the best game of the two matches.>

I wouldn't disagree too strongly with that, but I wouldn't rate it quite the same. Here's the order in which I'd rate Petrosian's wins:

1. 1966, Game 7
2. 1969, Game 11
3. 1966, Game12
4. 1969, Game 20
5. 1969, Game 10
6. 1966, Game20
7. 1969, Game 1
8. 1966, Game23

Although it's close because all but the last two were really strong games. In 1969 Game 1, Spassky went wrong at the very end in an ending vaguely similar to Fischer-Spassky, Game 13. In 1966, Game 23, Spassky avoided a repetition even though it meant taking an inferior position, just because it was a Must Win Situation. That takes a slight edge off those two games, compared with the other 6.

Not sure what Spassky's best win of the two matches was. There are several good candidates. Maybe Game 4 of the 1969 match.

Oct-03-18  Howard: How about Game 5, of the 1969 match as far as Boris' best win ?

Also, regarding that above list, Soltis rated Game 10 of the 1966 match as one of the top-100 games of all time, though it didn't make your list.
