Subject: singular extension (PV part only)

So when in PVS I've searched my first move, and it is a PV
move as well, with search returning value then I do a depth-2
search on all other moves  and if none -search(depth-2,-beta-MARGIN,-
alpha-MARGIN) <= -beta-MARGIN, where MARGIN is set to 3/4 of a pawn,
then the PV move  is singular and I re-search it with depth instead of depth-1
and use the returned value as my score against which to
measure all other non-PV moves against in the normal part
of the search, searching them to depth-1.

Is the above wrong?
