Posted: 17 Apr 2009, 03:17Quick reply Graham, I barely had time to try it out 
This critter seems pretty scrappy, hmm in the 2300's on the UEL scale, from the few quick 3/0 tests I tried:
Critter 0.34 - Glass 1.1 1-0
Critter 0.34 - Gibbon 2.52a 1-0
Philou 2.7.0 - Critter 0.34 0-1
GreKo 6.30 - Critter 0.34 0-1
Critter 0.34 - Arasan 11.3 1-0
Yace 0.99.57 DC - Critter 0.34 1-0

Hmm - not too bad if those early results can be considered a good indication. Thanks Tony.

I have it losing on time a lot here in move 40 in x/y time control. It seems it often tries
to finish the last ply when failing high or low and ignores the time then?

It doesnt try to finish the last ply even when failing low. The problem is probably that search termination has a latency about 40-60 ms (at least on my machine). Arena seems to tolerate that. I'll try to fix it in the next release.

Hi Richard,
That could be the wellknown problem in Arena, which even allows to reach the cut with negative time
on the clock(which is a bug)! WB doesn't forgive any 10th of milliseconds. I have a lot of logs here with Polyglot
timestamps which show that CritterChess doesn't move at the given time in move 40.
I will happily await your next version
