With so many people posting games on these forums:
Do you idly flick through the game?
Fast forwarding the dull opening scenes before staring intently as the action starts. Wondering how your performance would compare?
Is your right hand working overtime as you imagine future permatations?
Or do you lose interest half way through and think why am I watching someone else do it when I could be doing it myself?
Is your partner worried you are spending too much time with Red Hot Pawn?
Are you a chess voyeur?
