The point is this...  If you are going to go into a competition with an
unknown opponent, you had better base your methodology on known ideas and
strategies.  _not_ on trying to spring a tactical trap that your opponent
might (or might not) overlook.

IE practicing tennis against someone with a weak backhand will teach you
a bad idea if you happen to go up against someone with a better backhand
than forehand.  If you don't know what your opponent is capable of, you
should be prepared for both.  Not betting on just one weakness that might
not be there.

No doubt...  But his "advisors" _really_ let him down in the second
match, IMHO...
