Sorry, but this seems more than a little bogus to me!  These "helping moves"
remind me of Diego Maradona's "Hand of God" goal, i.e. it just looks like
cheating to me.  What I mean is that, given any two competitive programs,
inserting a couple of good moves for weaker ones at the right moment will
probably guarantee a victory, so it doesn't mean as much as it would if it had
played all of the moves by itself.
