Dan, prepare to be amazed... I copied and pasted the position into the two
programs that accept epd's correctly right off -- Zarkov 4.30 and Genius 6.5.
Zarkov came up with the right continuation immediately and saw that it was
winning, but did not announce the mate in about two or three minutes.  However,
Genius 6.5 was just incredible -- it announced _mate in 10 in 16 seconds_, with
me logged on, and with a couple of other apps running on my PII-400...  So, be
amazed :)))
