It might be pattern matching but I am not sure about parallel
search. E.g. when I see a certain [life and death] shape
(like dead L shape), I know the result as soon as I recognize
the pattern, and that's immediately, because knowing the pattern 
includes knowing the related local game tree. So my brain just 
applies some "hash" rather than any parallel search with a
collection of partial aims. I assume that professionals have
similar access to global middle game positions as well. This
"good first intuition" is the result of 10000s of patterns of
studied games. So IMO a player can become professional by
seeing and remembering 40000 positional types and 40000 tsumego
patterns. A computer must be taught a proper interpreter, if one
wants to use the same approach.
