Yes I just looked it up. Svidlers interview after the round 11. Svidler memorises his game against Ivanchuk in linneares. With just 5 seconds on the clock (for Chucky), he was doubting between two moves. The first one was objectively the better one, but the second move contained a difficult trap which would be hard to spot. Svidler taught, well with just 5 seconds on the clock, why not go for the trap? Ofcourse nothing good camed out of it and Svidler lost the game.
After the game, Kasparov come to him and ask: "What where you doing?"
Svidler responded: Well yeah, there's this trap there
Kasparov: You are playing Ivanchuk, what trap?! You just need to play the best moves and you go on.

At the candidates tournament I also heard a good one. I thought it was Svidler who recalls a conversation with Kasparov a couple of years ago. Kasparov, who followed the match Svidler vs Ivanchuk comes after the match to the table and has an question for him:
Kasparov: Why did you play that move?
Svidler: Well, there's a little trick if...
Kasparov: You play Ivanchuk, there's no trick. Just play the best possible move!
The reason why I like this story, is because I like to go for tricks and traps aswell. Especially when I play against someone who is 200 points lower rated.
