Korchnoi: Norm giver, norm spoiler. Still feisty after all these years.
Gibraltar 2011 - Round 9: " "Against some people you should not play the Kings Indian" I said "Yes thank you, I understood you in German. Korchnoi " I just wanted to make SURE you understood me". He then left feeling very pleased with himself."

Gibraltar 2011 - Round 10: Aleksandar Wohl: "I woke up in a foul mood this Morning. ... I got to the Board to find out I was playing an Opponent who needed to beat me with Black for an IM norm. "This Game is really important to me" he said. "If I win I get an IM norm". Bit of Advice. NEVER give your opponent Information that might be useful to him. Did he think I was Santa? Anyway now that I knew that he was obliged to go Nuts I knew that I did not need to. His attempt was quite sad."

Here is Eugene Torre's description of his last non-GM draw. (Since he was not a GM I think then it is not a much maligned GM draw.
)
"Viktor was a bit puzzled with all the press and asked Campo why there were so many cameras. Campo told him and asked if it would be a good game, sort of a probing question to see if Korchnoi is in a fighting mood. The Soviet chess great replied with a smile and, a few minutes later, acceptance of a draw offer on the 14th move."

Seems Viktor the Terrible is more complex than some might think.
The same situation arose recently when Sam Shankland had his last non-GM draw against King Loek. "I offered my distinguished opponent a draw on the 6th move. He smiled, said “I’m not going to make your life miserable again” and accepted the offer, thus clinching me the norm."
