	Nalimov tablebases are more complete. I do not know exactly which endgames are
available in Thompson's format; but for Nalimov's you can get all the four men
endings and all the 3+2 five men endings from crafty's ftp site (and you can
generate the remaining 4+1 endings, but I doubt they are very useful).
	Also, Nalimov tablebases can be probed in the search by crafty and CSTal2, and
I expect that more programs support them in the future.
José.
