Just a little post to work off frustration with my program, FreeChecking.
I know it's not very good (around 1700-1800 ICC blitz when not broken), and it
makes up for lack of quality by being slow, and I've been rewriting parts of it
to simplify the spaghetti mess it had become over a couple of years of very
intermittent coding, but still...
You know something's wrong somewhere when from the starting position, no book,
your search gives something like this (fixed 9-ply search) :
FreeChecking mode=test ply=9
Vars : cp(W) ply(9) pos((null)) trace(trace.txt) hash(23) phash(21) spec(TEST)

I can't believe the final PV that my program is generating. I would suspect the
new search, except the old search didn't do any better. Probably something with
hashing, evaluation, or something else. :-)
