I have not looked at the game in any detail yet.  But one potential issue that
is _always_ present is that I have very carefully tuned this program to avoid
the traditionally "drawn" type positions with pawns blocked.  Which is, I
believe, a good strategy against humans.  But against computers, it can cause
it to lose games it should actually draw.  At some point, I will probably make
this a "computer" option so that against computers it gets turned way down,
while against humans it stays active.

But for the moment, it is playing with _exactly_ the same code as is used on ICC
(version 18.10) and may well be haunted by this again...

If this was the problem, of course...
