user11173: Can the knight and king in anyway mate a queen and knight?
I was recently playing a game which I lost. The player with the king and queen was playing suboptimally. On the last move I captured a pawn with the queen since I was low on time.


user4418: No. The problem is that the queen covers too many squares.
Consider this (illegal) checkmate position with king and 2 knights vs king and queen:
[fen "kq6/2N5/KN6/8/8/8/8/8 w - - 0 1"]

If you remove either knight then the queen can take the other one.
