<Players who are devoted to certain opening systems know how unpleasant it can be to play against oneself in the purely psychological sense> - Efim Geller.

So says the man who beat Fischer with his own pet variation, the Poisoned Pawn Variation of the Sicilian.

Perhaps it is based with Korchnoi playing many times against Geller. There maybe situations against Korchnoi where Geller took lots of time before making a move,and that move is a mistake.

Classical games: Viktor Korchnoi beat Efim Geller 11 to 6, with 15 draws.

When Petrosian and Geller drew their final game in 1983, they hadn't had a decisive result with each other in 20 years, and most of their games stopped being real ones. There are a lot of other long-time opponents who do the same thing.

Vasiliev's book explains that in their Round 1 game, Petrosian was amenable to another draw as usual, got a slightly superior position, and offered it. But Geller was in a fighting mood, said no, Petrosian got rattled and lost.

The next time they played, Petrosian had to avenge that loss, of course, so he went out and played one of his all-time best games. So, two decisive results. But had Geller taken that draw offer in the first game, probably both games would have been drawn.
