If I would have used only whole-board patterns, of course the system would
only have been able to predict games that contain the exact same positions
(Fuseki most likely).

But there is such a thing, in Go, as "Joseki" and "Good shape".
My pattern system knows those patterns.

But it also sees simple tactical patterns and all kinds of other patterns.

For example, it looks a the board and sees a pattern on the left (the size
of half the board) and a pattern on the right (also half the board).
Together, those patterns have never occured but they have occured with other
patterns.

Those other patterns have been correlated and their value os known.
The system derives the RELATIVE value of the two halves of the board from
the other patterns.

Then it decides on that basis that one pattern is more important than the
other.
