Well, *my* engine takes longer than that to find it!

I guess it depends on the particular instance of human and engine you chose to compare.

Hello:

Same here. Once I was aware that it is a problem, around 3-5 seconds to spot QxN on my own, specially if ..., PxQ?? follows, leading to a checkmate in three moves. If I had found this position in an own game, I problably would not have played QxN.

Regards from Spain.

What I found great in this position, is that even after the queens exchange

black is still forced to capture the bishop with the rook ! the mate line is still pending because of the undevelopped black bishop.

And this alternative is still horrible for black
