Crafty has the most complete epd analysis of any tool I have ever seen. There are two flaws you should be aware of. If there is a single forced move, crafty will not try to analyze and will give an eval of 0. These are easy to detect because acd and acn are both 1 and ce is zero. Secondly, if there is a tablebase draw, crafty does not report it. The only way to discover this is turn logging on and watch the output window. When it says "trying to swindle" it has detected a drawn position, but hopes the opponent will blunder. This one is not as serious (IMO) because crafty will still write a ce which will draw your computer to the right move. It is just an artificially inflated score. Get one of the epd test suites from my epd directory and give it a try. -- C-FAQ: http://www.eskimo.com/~scs/C-faq/top.html "The C-FAQ Book" ISBN 0-201-84519-9 C.A.P.
