Oh well it's a mate only searcher. Let's give it a huge mate
(which a selective searcher could find real quick btw)

8/Bk3p1p/1P3p2/KP2n2p/1P1p4/1Pp2p2/B1P5/7B w - -

If it finds a mate here, please post the line,
as i don't have the winning line for this position. I know how to win
it, but DIEP will not soon see a mate here, stack problem...
...but i like to keep my mating probs complete.
