Everybody uses minimax search, with alpha/beta pruning.  In the SEE code you
are looking at most likely, there is no _search_ being done.  The pieces
bearing on a particular target are enumerated in increasing value of piece
order, then the 'minimax' result of that potential sequence of captures
determines who would stop first if anybody...

It has nothing to do with the search, however, it is used to order the
moves only.
