Puzlle 11603 is wrong

http://de.lichess.org/training/11603
The last move suggested by the puzzle is QH2, while actually taking the enemy queen with your king leads to a forced mate on H8.
Do I overlook something? If so, then Stockfish level 8 did so as well as me playing against it turned out exactly as I describe, mate in 2 moves.

You probably gave the link to a different puzzle.

Oh, my bad. I went for another solution which isn't mating (wins a queen), but still accepted by the trainer (which is weird). I played Ne6+ instead of Re1.

And yes you're quite right. Kxh2 is a mate in 2. I guess that's the reason Nd6+ is accepted, as the trainer sees no mate.

Someone really needs to fix the quality of these puzzles if mates are lying around and being denied as the solution. 2nd thread I've seen about this today.

Quite annoying to come up with the right solution and being told that you're wrong...
