I know that a lot of you are going to think that this is stupid but here is the issue anyways:

We all know that a pin piece to the king cannot legally move anywhere because then it would leave its king on check. What if there is a piece using that pin piece as defender to checkmate the opponents king, why cant the king take that piece if the defender cannot legally move?
