What mystery? Some application not seeing a mate in 14? The other day someone brought up a mate in two wasn't seen by a random engine. WHO CARES? 😛
Well, if it doesn't give you a move accompanied by "yippee I saw mate in 14", what output does it give to you? It might be interesting to see. There are always many details hidden in any chess position, nobody sees them all, let alone chess engines. For example why isn't this a mate in thirteen? What little difference in the position would make this a mate in thirteen? It takes six more moves after White has captured the Bishop. Why not only five?

Yes Monk is one of the best American programs to reach us for ages.
Reminds me of Columbo.
I would not be too hard on Black in that game.
He did the human thing. The Queen and Rook on the 7th looked like
it had chances but the box had it all figured out.
It must have seen the heart breaking 27.Qc6 a long time before Black.
Powerful game,
