  Thanks for the example. Now I understand.
  I have thought about patters sometimes. The problem I've always found is: a
pattern (in this context we're talking about) is a subset of the board. In an
endgame position with few pieces you could probably use that scheme, but what do
you do in a midgame position full of pieces?
  If you use locality to determine the patterns (in your examples, all pieces
are within the same area) you miss the action of sliding pieces from the
distance. It could be possible to find the distant influencing pieces, and
include them into the pattern... right?
