Well we all use a constant window, we set to the previous iteration +/-
some kludge factor and off we go .....

When we get a new move at ply one, then alpha gets uprated .....

Further what alpha/beta changes do you want ? As we progress through the
tree, because the changes are going to coem thick and fast; or do you
want the window before each move is expanded at ply one ?

And I ask again, why, what are you going to do with the information ?
You know that the aspiration window gets set off the previous iteration
score; you know the new value of alpha every time the ply one best move
gets scored.

Why do you want this stuff ?
