I forgot to add that playing close to last opponent move worked best so far
with the progressive widening.
In this scheme it fights the opponent at every move locally ,but will not
have the initiative to explore other opportunities
in other areas of the board. The opponent basically dictates where the
fights take place. Maybe I should add some randomness to avoid this
predictability issues ? Using the other static schemes made it too
