Subject: null move and mate threat

Author: Stuart Cracraft

Okay so on the one hand I am supposed to do a reduced
search for null move with bounds -beta,-beta+1, and
return if the value is >= beta.

The mate threat has to be compared with a mate value
but the beta's above aren't relevant. Do I need to
do a second reduced search after the above with bounds
-MATE,-MATE+1 and see if it is >= MATE and if so set
the mate threat flag to trigger the extension???
