too many wrong tactical quests

there are too many faults in the learning program like for example: Aufgabe 66547

What exactly do you think is the problem with that puzzle? What do you want to do instead of the mate-in-two on the board, and why do you think the system should accept whatever inferior move you suggest? Is rewarding people for making bad moves a good way for them to learn?

Let me guess, you don't even bother checking your answers with an engine, do you. You just assume the solution is wrong. Because you can't be wrong, it's unthinkable.

Have you checked 66547 before writing this ? I don´t think so!

I did. It's a mate in 2. What do you suggest instead? Do you see a mate in 1?

@Dendrobates Imagine posting this thread in the first place without explaining what you think is actually wrong. Then, imagine being asked to explain what you think is wrong, replying to that, but STILL not explaining what you think is wrong.

Either you have given the wrong puzzle number, or you are wrong. Those are the two possibilities.

It is about who does the work of explaining the possibilities. Better you propose something to narrow that down, or people might get indisposed, and that will go downward from there. difficult tone to rewind.

I guess he thinks the black pawns move up and could capture the rook.

They don't

The game's comments are full of people who made that mistake but no one is complaining that the puzzle was wrong.
