Mate in 3 move that an angine can't see

I'm highly doubting it.  I dont think Stockfish misses mates in 3 anymore.  

There is no mate in 3 here

There is a mate in 3, I think...but only if your opponent stupidly moved his Knight away.

Maybe...bishop to h7 for a check.

If knight takes, then queen retakes knight on h7 for a check. Black King retreats to f8, then queen to h8 is mate. That's 3 moves, so maybe that mite work.

If king moves to h8, move bishop to g6 for a check. Black can either move king to g8, or block with knight to h7, but then queen will take knight is a mate. So if kg8, go Bf7 for a check, at this point black has to take with his queen which u can later take with the knight. It will then b queen v blacks rook n knight. But yea, I don't really see a forced mate in 3 unless black slips up in the first scenario

stupid wher checkmate??? if Bh7 .. Kh8 no mate

Pleas e give Lago a Trophy "if" he can solve this problem.
