Questions for a Grandmaster

Hey I got a game with Suttles in the skittles room when I was visiting a tournament before I ever played in one. Of course I was mystified, but he would have done that to any normal master, much less me a raw beginner at serious chess.
Petrosian was likewise a mysterious opponent for many, even strong players.

One of the chess websites had a cool project where anyone could ask a particular GM (e.g. Grischuk) anything he/she wanted. Chess.com could also arrange smth. like that, I guess.
