Nothing wrong with your testing... I just pointed out that if you play a match
between (say) fritz and hiarcs, hiarcs will probably do better at 1 0.  Not as
well at 2 0, and it will keep getting worse as the time control gets longer,
because null move failures become less frequent...

Thorsten and I once had a long discussion about his playing some version of
CSTal vs Crafty, but he was using very slow computers and fast time controls.
I told him I was developing on the P6/200, and that if he used that sort of
machine, the ugly crafty losses would disappear.  He changed hardware, and
then reported that suddenly things were _far_ different with no obvious tactical
mistakes dropped into a game by Crafty.

Null move is good and bad.  The longer the time control, the fewer errors they
introduce...
