Subject: EPD tests a little leaky...

Mike Byrne over on r.g.c.c. just found two more (he found a total of five!)
negative checkmates in the first twenty rows from the rockpile.  No wonder they
are so hard to solve -- they have no solution. ;-)

It is rather amazing how many of these problems have less than ideal answers.

For quite some time people have been basing the strength of their computer
programs by running against batteries of these tests, as one measure of ELO.

Maybe we need to look over the tests very carefully.  It could be that an 80%
score is 100% right and a 100% score is 20% wrong!

Maybe you have thought -- darn it!   My program keeps getting the wrong answer
on this problem!

OTOH, maybe your program was right all along.
