I think I have pointed this out in the past.  I don't think Crafty is very
good at blitz time controls, compared to other programs.  Many of the
assumptions I make really hurt it at shallow search depths.  IE unrestricted
null-move R=2, capture-only q-search, etc.

I certainly think it plays better at longer time controls...  for those (and
other) reasons...
