Hi John
Here is one of the positions i tried, a mate in 6.
6k1/R2b1p2/3N1npp/3p4/3P4/4PN2/2Q2PPP/6K1 w - - 0 1
With both players human, i went to edit/paste/Forsythe Board Position and pasted
the position. The Mentor Lines window has to be opened first, since there is no
way to open it after "Solve for Mate" has started. I get the following in the
Mentor Lines window, and Solve for Mate still hadn't solved the mate after two
minutes, so i stopped it.

Time	Depth	Score	Positions	Moves
0:00	1/8	Mate07	100162		1.Nxf7 Kf8 2.Qxg6 Ke7 3.Nd6 Ke6
					4.Qf7+ Kxd6 5.Qxf6+ Be6 6.Qe7+
					Kc6 7.Qc5#
0:01	2/9	Mate07	172016		1.Nxf7 Kf8 2.Qxg6 Ke7 3.Nd6 Ke6
