Chessmaster6000 can see mate in 20 at depth 2/12(time 19:12) and does not change
its mind at depth 3/13 or 4/14

pv Rxf7 Bf6 Rxf6 gxf6 Qe6+ Kf8 Qxf6+ Kg8 Bf5 Qc7 d6 Qg7 d7 Rd8 Qxd8+ Kf7 Qc7
Rd8 Qxd8 Qf6 Qxf6+ Kxf6

I do not post more moves because my screen is too short but in this line there
is a shorter mate than mate in 20 so I suspect that there is a shorter mate.

I think that the result of mate is better than the result of mark young that
does not give a forced mate inspite of the fact that chessmaster did not see 16
plies.
