This puzzle is from a game. How often do you actually make a "devastating check" In a real game? I´d say its a good move, but in a puzzle everything becomes a lot easier, since you know the number of moves its done in. Well, you could always try to make a puzzle outside the book, with more effort your self, if you don´t mind me saying so. Or perhaps you should ONLY try the harder section, since the easier doesn´t give you anything but a bad breath after vomit. Nothing personal to you chessikins, but there are just so many yawn-comments, we can be without, many of us actually like the easier ones. Have fun.
