You want, probably, say that you looked into some >program by doing your own, but if it is so, what exactly? Sorry Leonid, that remark was for Heiner, see his message from earlier today: http://www.icdchess.com/forums/1/message.shtml?193869 TSCP is "Tom Kerrigan's Simple Chess Program". It has a basic board structure, move generation and alpha-beta search, a (very) small evaluation function and is very clearly written and easy to understand (if you can read C). In short, IMHO it is *the* program to read if you want to start programming one yourself. I used the first version of it to start my Pretz project. I wish Heiner's "Chessmaster clone" remark was true, because that would mean I'd know the insides of Chessmaster, boy .. that would be something! I think it's a really really (ok ... one more :) really great program! Except for the fact that my CM6000 doesn't seem to work correctly on Windows XP. Installed it just now and tried your last position, the first try took 6 minutes, I thought: wot? that can't be right? ... and on the further tries it just froze. :( Must be doing something wrong, but what? >Mate is really easy but still you almost reached me on this one. Mine took 3.8 >sec (can be said 4 sec) to find mate by selective in 10 moves deep. But I used a p3/1000 and a hashtable for this, sooo ... :) >It is mate in 10.

I'll leave the details to Herr Marxen. >>00:04 WM10 07 Rxb7+ Qbxb7 Qcxc5+ Qxc5 Qgxc5+ Kxa8 Nxc7+ Qdxc7 Qa5+ Qga6 Qaxa6+ >>Qa7 Qaxa7+ Qxa7+ Qxa7+ Kxa7 Qhb6+ Ka8 Qa6# > >Cheers, >Leonid. Groetjes, Paul
