I haven't seen the movie yet but it is dramatic effect. FIDE has tried implementing draconian rules more recently where being late to the game would incur a forfeit. I believe they have become a little more reasonable and as far as I know, nothing like that was in effect at the time.
edit: I meant the one minute thing. I believe if a player was an hour late they would forfeit the game. So, if that was what was being shown, then something similar may have happened ... he did show up late to games and I believe his first game of the championship he almost did lose by forfeit.
In Pawn Sacrifice, it is shown that in a match, Bobby Fischer arrives a little late, then adjust all his pieces and gives his move at the 59th second...he would have lost in case he would have failed to give a move before the 1 minute mark.
I have read quite a bit about Bobby Fischer but I had never heard of this. So is it a true fact or has it been shown to enthrall the people watching the movie?
In case this is a true fact, any citations would be of much help to me.
Thanks.
