the puzzzle is incorect

And to stanislav90 and myzqwe: if you make such claims, you should at least substantiate them. How is the puzzle incorrect? And which checkmate in less than 6 moves is there? I think there is none. You can aways try the "Another solution" link in the right bottom of the puzzle window, if you think there is a shorter variation that also leads to checkmate (or another one in the same number of moves).

I would give 3,5 stars at most. The first move is quite obvious. At least it is the most probable option to try out first. For the second move we only have 2 options that give us a direct mate threat: Re1 and Rc7. It took me little time to conclude that Re1 does not lead to much, but Rc7 actually does. Black has just two defenses: Rd7 or Bd7 (and of course a delaying queen check, that can be ignored). In analyze mode it is actually not that hard to find that both answers lead to a quick checkmate. And indeed, the variation with Bd7, is a little harder to figure out.

1.Qe6 fxe6
2. fxe6#

The Queen taken by the pawn leads to mate.
