This problem that I show below has two solutions, you can move any of the two towers, the final resolution of the problem is absolutely the same, if you choose the correct tower to play, the problem is correct and you add points, but if you choose the other tower what you get is to subtract 14 points, as happened to me.
Initial position.
Wrong movement.
Correct movement.
I encourage you to look up the problem and see that both solutions are possible, the end result is the same, so both solutions should be accepted as valid, and you can add points for both, and not lose points if you choose the wrong one.
There's no issue with the solution.
Rd1 doesn't work.
1. ... Rd1+ 2. Rg1 Rxg1+ 3. Kxg1 Kg3 4. Rc4
There's no mate threat and black does not win the rook as in the solution
