Styleone: You have a point there. though I prefer 2 days, I could live with 3.

Chaos:

Why not go with the alternate time control. Say 7 days + 2 days per move bonus time with a 15 day cap? That lets players 'bank' some time if they know they might be away from their computer in the future without necessarily doubling the length of the game.

happy hermit: Sounds to me like a game could last quite long that way. Is the limit the limit for the total game or for the bonustime? I never got that right.

Chaos: A player could take a long time (up to 15 days) on a particular move, but would have to maintain an average move time of around 2 days (not counting weekends).

happy hermit:
This sounds like a good idea.
But how can you control this feature in BK?

dAGGER: I have never set-up a tournament, but when you set-up a new game (for the waiting room or to send an invite) you get a screen to 'Select this game parameters'. You can select the time control there. One option is time per move, the other has three options: game, bonus, limit. These correspond, respectively, to the initial time allowed for a game per player, the bonus time awarded to a player after making a move and the maximum amount of time a player can have to make the next move. It's a built in feature and, in my opinion, the biggest advantage of this site compared to IYT.
