Actually, EXchess only sees some of the problem at 6 ply.  It fails low
again at ply 8 on Rg8.  This fail low isn't shown in the output because
I don't show a fail low if a better move is found (laziness on my
part that I have been meaning to fix), but you can see it switches to
Rxg5+ at ply 8 without posting a score for Rc8.... meaning that Rc8
failed low.

The only things I have done to EXchess recently is a little tuning
and killing some bugs.  One of which was in the endgame and very
nasty  (I was using a signed char to store a value in my pawn
hash tables that could, occasionally, be larger than +128..... ugh).

I would love to drop into ICC and do some stomping (yeah, right....), but
my human account expired a month or two ago.  I have other things to do
with $40 right now than re-up my membership....  My computer account
for EXchess is still active, but I am not sure if I am allowed to use
it if my human account has expired.

Another problem is that while I enjoy small distractions, large distractions
may not be so good for me right now (ICC is a much larger distraction for
me than FICS).  I am trying to write up my research in the form of papers
and my thesis (really one and the same) so I can graduate in June (ok,
maybe July....).
