I use 40/6'+20/3'+game/3' time controls for engine v engine tournaments on my
single cpu machine. I use fritz8 gui, amd 2000xp+, 128M hash each, nalimov
3,4+some5.
I have been noticing a time management problem that affects several engines. I
think it has to do with time lag in accessing nalimov 5man files. The egtb cache
is 16M each. Any help in figuring out what is going wrong is appreciated.
Here is an example of the problem. In the game below, fter the the 79th move,
Arasan (white) has 22 seconds left and Leila (black) has 21 seconds left. The
position is a textbook draw. However Arasan rates the position as 2.12 for
white, and Leila rates it as 0.20 for white.
For the 80th move, Arasan uses 14 seconds and Leila uses 12 seconds. Arasan
(white) has only 7.5 seconds left and Leila (black) has 9.7 seconds left. Their
ratings of the position are unchanged.
At this point, both engines go into "panic" mode and start to move as fast as
they can. However they are also accessing Nalimov 5 tablebases (there are 6
pieces left on the board). Their moves each take 0.3 seconds each. 22 moves
later, after move 102, Arasan (white) has 0.1 seconds left, and Leila (black)
has 2.1 seconds left. White made 22 moves in 7.4 seconds, and black made 22
moves in 7.6 seconds. White rates the position as 3.04 for white, and black
rates the position as 0.20 for white.
White has to complete its 104th move to invoke the 50-move rule (white made a
capture on move 54). There is not enough time left for white because the moves
were not made fast enough, or to put it another way, it went into "panic" mode
too late. Black is also in time trouble, but fortunately for black, white is in
worse trouble.
White loses on time while working on its 103rd move.
