In the last game of Tal, he won against Kasparov, because Kasparov lost on time. So how many minutes do they have?
It completely depends on the event.
Do you know how much time did those 2 have in that tournament?
In those tournaments, it was 120/40 and I have no idea what else.
Sorry for my ignorance, what is 120/40?
According to Wikipedia his last tourney was the Moscow Blitz tourney. So, I would guess 5 minutes per side.
