But as you don't know how many moves the game will last, you will probably move faster. See: 40/120+60, first 18 moves out of book. Leaves 22 moves in 120. There are SOME! programs which use >10min per move up to move #35 and play the remaining time faster. This is also awaiting some p.b. hits. g/180: I have seen Shredder move much faster (certainly because there is no implementation to use more time for the moves up to #40), and I have operated Century 4 in the Thueringen tournament last year where Century rarely used more than 6min for a move while in 40/120, as I already said, take about 10 or more minutes. You can see it in the annotations I provide in my game databases. >Does shredder use less time for the first 40 moves >when you tell it g/180? Yes, definitely. >Is there a program that always use the rule of using more time at slower time >control? What do you mean exactly? Comparing g/120 with g/180 or g/180 with 40/120+60? >I suggest to test programs in the following situations with no opening book Personally I find tests without opening book senseless. >1)200 moves/200 minutes+1 minutes per game >2)g/180 >3)10 moves/120 minutes+1 minutes/game > >T(1) is the time that is used for the first move in case 1 >T(2) is the time that is used for the first move in case 2 >T(3) is the time that is used for the first move in case 3 > >How many programs have T(1)>T(2)>T(3)? > >Uri For all programs I have seen you will get it vice versa, T(1)<T(2)<T(3).
