Re: NICE 1.2

It works - AND I found a (possible) bug in Myrddin! It does not accept "st" command values less than 1, because the protocol says it is used to "set the exact number of seconds per move". I guess, when I implemented that more than 10 years ago, I never considered decimal values. :oops: But the text ...

Re: NICE 1.2

Well I'm stumped. Either I can't make it work with Myrddin (which is an xboard engine) or NICE doesn't support xboard. Has anybody had success using NICE with any xboard engine?

Re: How do you fix this.

Yes, you guessed it, I found a bug. Or should I say a dumb logic mistake. :oops: :oops: :oops: Beware of other subtle logic mistakes. It took me over two years before I realized there was a bug in Myrddin that caused it to fail to check if a move that would cause a 50-move draw would ALSO cause che...

Re: NICE vs CUTE

Excellent tool, Ed (and Ferdinand). Does it only support UCI engines? Winboard also, see the MEA help.txt file. Or use WB2UCI. Terrific! I've given it a try to get a base level, and here's the output that comes back very quickly. > .\mea --engine engines\Myrddin-087-64.exe --name Myrddin --protocol...

Mate in #8 :D
[d] 4k3/8/8/1p1p1p1p/pPpPpPpP/P1P1P1P1/8/RNBQKBNR w KQ - 0 1
Myrddin on 8 cores (yay new machine!) says mate in 9 in 3 seconds - but doesn't see Mate in 8 in a reasonable time.

Re: On-line engine blitz tourney April

The version of mamer-TD we are using for the tournament seems to use the players rating as tiebreak which gives very odd results, maybe it would be better to use the Fide rules or performance rating as tiebreak and add something like Buchholz or Sonneborn-Berger to it. I don't know if I have the op...
