Kasparov Karpov, time controls

Hello! Does anyone know, what was time control in these games (1984, '85, '86, '87, '90), with all adjournments and so on.

And how many games they were required to play? I mean, if someone reached 12,5 in game 20, was it reqired to play remaining 4 games?

Thanks for answers!

In 1990 they played 150 minutes for the first 40 moves and then 1 hour for every 16 moves.

I'm interested in that topic too! Thanks for opening it!

@Sred, was it connected? I mean, in one day?

@MSC157: No, they had adjourned games, playing time was 6 hours per day. Game 16, for example, was adjourned twice and ended after 102 moves.

Forgot to mention: if one of the players had reached 12.5 points before game 24, the remaining games would have been abandoned.

I don't know about the rules in 1984-87.

Today it's 120|0 for 40 moves, 60|0 for 20 moves and 30|15 (or is it 15|30?) for the rest. I don't know how was it in the past...

2 hours and a half for the first 40 moves

But now, If I'm not mistaken, I think it is just 2 hours per 40 moves.

thanks! we need to find out just from 84-87! :)
