- Improved thread management in the search agent class;
- Added safe margins to the poll routine to avoid the engine forfeit on time in some time controls (Problem reported by Werner Schuele. Thanks!);
- Code clean up;

Re: Redqueen v0.8
Here is a modified version of v0.8 with a 64 bit binary included:
http://cap.connx.com/chess-engines/new- ... edqueen.7z
I had to do some fiddling around with it to keep MS VC++ from throwing up on itself.
You have to have the pthreads dll from the archive included in the path also, or located in the working directory of the executable.

Re: Redqueen v0.8
Thank you guys from CCRL (Graham and Aser), CEGT(Werner), Sedat Chess(Harun) and ChessWar (Oliver) for the time spent testing Redqueen. It is helping a lot in further developments and keeps me motivated when I see Redqueen is climbing up in the rating lists. I know it is not exciting like testing the new Critter (what amazing chess engine!) but I promise I'll keep trying to improve it.Graham Banks wrote:Ditto.beachknight wrote:Thank you Ben-Hur.

I will try to merge your changes into the trunk version.
Thanks

Threading does not seem to be working correctly. Probably, I should change it to use native threads.bhlangonijr wrote:What a nice thing Dann! I always wanted to do this port to MS but never did.Dann Corbit wrote:Here is a modified version of v0.8 with a 64 bit binary included:
