   I'd rather call it the distinction between global search versus 
   goal-oriented search.

This is a misconception.  Global search is more goal oriented than
local search.  The difference is that local search has a very simple
goal that is not directly related to winning the game.  It has a
single goal that may or may not even be relevant.  Global search has
the goal of achieving the best possible position.  It is a much more
ambitious goal.  Probably too ambitious.

I think the secret will be how to combine the two.  I think it may be
possible to achieve deep cutoffs with highly focused local searches
someday.
