This mate is exactly 12 moves deep. I am not sure what is "epd collection", so I
presume that I don't have it. I do keep all my positions for me in graphics. For
priting them I use Fritz. Very neat picture. These positions are very handy for
verification of mate solver logic. I never put on my position indication of
solving move. I can find this move once again. This mate is not long to be
solved by brute force.

All positions are done with special mate solver that I wrote many years ago. It
is integral part of LLchess program.
