Neither.  The search doesn't cut off "moves"... it cuts off "sub-trees".

So a particular move has nothing to do with what is going on... it is
what happens at the terminal nodes that affect what gets cut off back
earlier in the tree...  So I *always* search to the nominal search
depth,
plus the extensions, plus the capture search, and then decide whether I
like that position or not.  Which has nothing to do with the state of
the
board after one of the earlier moves...  only with the state of the
board
after the entire path has been tried...
