Revert see() shortcut for LxH and equal captures

Revert see() shortcut for LxH and equal captures

It happens that more then 70% of cases are HxL, where
we call see() anyway. The mesured saving of calling
see is about 0,5% of total time, but considering the
added burden in score_captures() the saving is only
0,35% locally and due to more difficult inlining of
the function it ends up that we have no advantage at all,
possibly a small slow down!

So revert.
