hmm , i'm not sure of the meaning of you wink ;-)
int
trymove(int pos, int color, const char *message, int str)
{
UNUSED(str);
/* Do the real work elsewhere. */
if (!do_trymove(pos, color, 0))
the 4th argument is unused, so currently we dont care about it ?
so it is symetrical ? or i misunderstand something ?

I put + symetry for DD6 instead of 8, and as expected, the pattern is match
only once now (instead of 4 times), and save 1,5% nodes for this test.
I have not run all regression for this (it takes 2.5 hours on my laptop.)
