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.

Yes, definitely.

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.

For all programs I have seen you will get it vice versa, T(1)<T(2)<T(3).
