One should not be too quick to judge the difficulty of a puzzle; when faced with such positions in one's own games, few actually play the winning move.

I think I would have gotten this in a game situation.  I rarely miss a check by my knight - particularly when it isn't a sacrifice move.  And I'm usually aware of what my Queen controls.  And in this case, there were no alternative moves to debate over.

EDIT--Well, looking back at it, I suppose in a game I might be focusing on that threatening black knight at d1, and might think of taking it with my queen.  but the checkmate sequence is just too obvious to ignore.

Easy but not too bad either..
