It depends.  IE on any given day, crafty can beat anybody, or be beaten by
anybody.  Look at the results for "Le Petite".  It looked very strong.  Yet
it was an absolute copy...

That's the point.  I can't imagine someone working on an engine, in a vacuum,
for a decade, before anyone finds out about it.  I can't imagine anyone writing
a program in 6 months that would come close to beating _any_ top program.

Anything is possible, I will agree.  But the probability is so low that it
will make people wonder...
