See the above 2 posted positions. Yes people kick on a program
that finds it quick. Doesn't say anything whether it's useful for
game play indeed, as one sees very little strong programs lose
in world champs because of tactical blunders.

I can't agree with you here. It's real cool if you also have the
right score otherwise it might next ply go to a different move...
