I would not want to generate either KBNK or KQKR on the fly...  because
I probe *in* the search, and need the result then, not just at the root.
And KQKR can't be built in a couple of minutes by anybody yet...  the 3-4
piece files take 3-4 *hours* to build, in total...

        Fritz 5 can mate with KR vs KQ with no tablebase at 20 sec. a move. Mark Young 09:13:36 10/13/98
        
        Junior 4.6 also can win KQ VS KR without tablebase. Mark Young 10:57:38 10/13/98
