  mistermac: An interesting game in which I scored well to start with but lost points later. I will come back to this game to analyse it a bit more.
Apr-11-15  Howard: Well, it's been over two years now !
May-08-18  Albion 1959: Bad blunder by Petrosian on move 29, that resulted in the knight getting trapped. To his credit though, he battled on for another 40 moves before he had to capitulate !

  Sally Simpson: So that is why Two Bishops are better than Two Knights.

It's easy to make the same mistake Petrosian made. Here he finger-slipped the wrong Knight to d5

Easily done, Harder to do with Bishops, them being on different coloured squares for the entire game.

Good. It's been bugging me since breakfast why GM's say Two Bishops are better than two Knights, now I know.

May-09-18  Granny O Doul: I don't remember how to create game links, or perhaps I never did know, but anyway, as far as touching the wrong knight, this game is reminiscent of the famous game Ivanchuk-Yusupov from the last round of their 1991 Candidates match.

Korchnoi, though, picked up the wrong bishop against Bagirov in the 1960 Soviet championship, despite the bishops' being nowhere near each other. So I'd say the question of which thing is easier to do remains unanswered. There was a happy ending at least for Victor Grozny, as he went on to win his last three games in the tourney to just edge Geller and Petrosian for the title.

  Sally Simpson: Yes Granny O'Doul, it was this infamous game Bagirov vs Korchnoi, 1960.

Pity that unlike today they did not have a camera on every board.

The sight of Korchnoi waving his bishop about looking for a Rook to capture would have been quite funny.
