Black is clearly lost in the diagram position, but Houdini 3 comes up with some bizarre analysis:

[FEN "r1bq1rk1/5ppp/p4nn1/2p1bNB1/1p2P3/6NP/PPB2PP1/R1Q2RK1 w - - 0 19"] 19. Nh5 $1 {Deflection: f6} Qb6 (19... Nxh5 20. Qd1 {Decoy Double attack} (20. Bd1 {Discovered attack}) (20. Bxd8 {Deflection Pinning})) (19... -- $140 20. Nhxg7 {Wins material}) 20. Nhxg7 0-1

Do other programs also suggest, after 19...Nxh5, 20.Qd1 or 20.Bd1?

No after 19..Nxh5, they suggest 20.Bxd8!
