EXchess version 7.51

EXchess v7.31 is now available on my webpage...

Code:
https://sites.google.com/site/experimentalchessprogram/

I had not planned a release at this time, but Matthew Lai reported an bug in castling that needed to be addressed. Then I discovered a second bug in the endgame evaluation while testing. Both are now fixed, and there are a few other changes including the introduction of singular extensions and less aggressive reductions.

Thanks to Matthew for finding this bug and for contributing another patch to allow EXchess to compile smoothly under the llvm compiler on a Mac!

EXchess version 7.51

From Talkchess and Author ... Hi All,

just released version 7.51 of EXchess from

Code:
https://sites.google.com/site/experimentalchessprogram/

Changes include fixes to a couple of significant bugs, one of which made singular extensions essentially inoperative. I've also tuned a number of the evaluation parameters and made some changes to extensions and reductions. This version is about 40 elo stronger in self-play, but the gain will probably be less than that against other opponents.
