Summary: better chunking

I could be mistaken, but I think much of it relates to better "chunking",
as was discussed recently in this newsgroup.

Take a simple example. Suppose you are White to move with this board fragment:

		  BLACK (lower-case)
    ---------------------------------
    |   |   |   |   |   | r | k |   |
    ---------------------------------
    |   |   |   |   |   | N | p | p |
    ---------------------------------
    |   |   |   |   |   |   |   |   |
    ---------------------------------
    |   |   |   | Q |   |   |   |   |

Now, any experienced player knows that's a win for White. They no
longer have to visualize the details (N-R6+ K-R1; Q-N8+ RxQ; N-B7 mate);
it's enough to be able to visualize GETTING to this position, since
this position is known to be a win.

Presumably, better players are that much more familiar with the
various ways in which the pieces combine as they relate from different
positions.
