>mate in 30 moves.

Note that latest Movei only see mate in 32 from the original position and it
does not search for shorter mate

It's line is
27.Neg4+ Kf5 28.Nh6+ Ke5 29.Nf7+ Kf5 30.Nd6+ Ke5 31.Ng4+ kd5 32.c4#

Fritz gui for some reason do not understand movei's mate score and when movei
writes
32764 it translates it to mate in 1 and when it writes 32766 it translate it to
mate in 0.

It has no problem to understand movei's score when it writes mate against
itself.

I wonder if there is some bug in the chessbase gui that translate socre of
winboard engines to mate score wrong.
