Groucho: It's a tough question. The purpose of the clock is to encourage fast play. A game with a hour total and no bonus is going to be over in two hours maximum. But I've had games that have been quicker yet had 1 day clocks. That was against opponents who had my speed style, were online at the same time and didn't have hundreds of games to play.

Strangely enough the Very Fast Fischer's Stairs that I play has been slower moving than the ordinary Stairs!
