I have heard that doubling the speed gives a rating increase of about 60-70 Elo points (or some such). So presumably doubling the time taken in a time control would give about that increase in rating. There is a practical limit because after a few hours (or days?) the calculations will "hang" in real time, i.e. it will take too long to calculate the next ply depth to be practical. --JRM On December 22, 1999 at 12:07:25, Michael Fuhrmann wrote: > > >Imagine a graph where the strength of chess program is the vertical axis and >time control is the horizontal axis.
