This is a really tough test suite, intentionally.  If your engine gets 80/80 at
20 seconds per position, I am ready to announce it as a GM on the spot, despite
the unscientific nature of any such announcement (barring a cook, that is).

Some are positional moves.  Others are simply deep tactics (but positional moves
become tactical moves if 'deep' is deep enough).
