Subject: an endgame test position

aloha!

after all the cloning talk, here's something to test your favorite engine with:
i played a weakish IM today and got the following position after 56...Qg6+
57.Kf2:

[D] 8/6kp/8/3p4/1P4q1/P4p2/5K2/4Q3 b - - 0 57

it took me a couple of seconds to see that after 57...Qh4+ 58. Kf1 Qxe1+ 59.
Kxe1 Kf6 black is completely winning due to the floating square (it's nice to
see that reading dvoretzky is some good!) and so i played that and won :-)

interestingly, when i entered this game in chessbase running fritz7 in the
background, fritz didn't seem to see this at all within a minute or so. so
question to all: how long does your favorite engine need to see the line ...Qh4+
Kf1 Qxe1+ with a HUGE plus score (i.e. +9 or so - that is what my assessment of
the position was after a couple of seconds...)?

i don't want to claim that this is the only win, but it is by far the easiest
one, and fritz 7 misses it completely.

cheers
