In Chess Mentor Lesson http://www.chess.com/chessmentor/view_lesson?id=4891 (Jacobs - Rosenkjar, USA 1945; "Chess Traps and Miniatures Part 2- Checkmates"), white's third move Nxh7 is considered incorrect, claiming "Continue the attack on the enemy King. Look for discovered attacks."

However, the move is perfectly fine, since (a) we are dealing with a discovered check and (b) black's only valid move is Kh5, which will lead to checkmate after Qf3+, Kh4, Bg5#. This line of approach is also stated in Chess Mentor's next commentary, which states "Any move by the Knight would have led to checkmate."

Could someone fix this?

Thanks,

Casper.

I don't guess this is too much of a problem.
