you're only rated 1609, and you think you know better than the rest of the chess world. I'm sick of people assuming the tactics system is chock full of errors. As far as I can tell so far, it is in fact inerrant.
What !! You are sick of people trying to think for themselves? I don“t think you are going to make much of a progress yourself. kingdawar simply gave a polite answer. All the best in the future and enjoy the game full of silly problems and sometimes very unaspected solutions.
if Kh1, 2...Qxh6 #
If QxN, 2...Qg6 and the only delay to mate on g7 is Qe5 or Qf6, which is taken by 3... Bx at b2, then mate 4...Qxg7#
I am sick of losing points when I find a quicker better solution.
