- Implemented pawn hash table (finally);
- Many code optimizations (piece square calculation, legality of moves, etc);
- Evaluator class was refactored;
- Evaluation improved: Added more chess knowledge (space, "good" mobility);
- Fixed bug at pondering code: it was not handling correctly the "ponderhit" command;
- 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;
Source & linux64/win32 binaries:
https://sourceforge.net/projects/redqueenchess/
v0.8 svn tag:
https://redqueenchess.svn.sourceforge.n ... elease-0.8
This version scores about 58% against version 0.7.5

Here is a modified version of v0.8 with a 64 bit binary included:

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.

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.

What a nice thing Dann! I always wanted to do this port to MS but never did.
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.
