I was`nt aware that this version of gnuchess had been released, It is a somewhat premature version. The version I had intended for release was posted to fsf 27 june. I wonder why this version has not been released yet. There is actually an even newer version with some very rare (probably newer encountered) bugs in version 1.52 corrected. memcpy can be an improvement in some places but this depends on the machine you are using so thats why they are commented out in the official release of gnuchess. I would really like some feedback on the new move generator. Send this to my address below.
