When these programs find #1, do they choose Nxh6 only for a very small
positional reason (instead of choosing Qd4 or some other move)?  Do they
actually find that this move is winning?  I think the key move to position #1 is
after 1. Nxh6 c3, and the move is 2. Nf5.  IMO, this position isn't solved
unless A) 2. Nf5 is found and B) a winning score is returned for white.
Otherwise, the engine will play 1. Nxh6 and still lose, therefore defeating the
purpose of finding the 'brilliant' move.

That's a nice result from CM5555 on position #2.  I know DT2 solved this one in
a couple minutes, with correct score, but we can hardly expect to match their
results for this test. :)
