Puzzle goals.

This is a pretty minor thing that I find annoying. Does anyone else find the virtual coach can give misdirecting advice on the puzzle goal?

I just did a puzzle and the coach started by saying something along the lines of your pawn is trying to promote, there's only one way forward.  I take that to mean the goal is to push the pawn forward to promote.

I couldn't see anyway to promote so I clicked asking for a hint and it said "Find a way to take my castle"  This was actually pretty easy, but it involved letting the castle take your last remaining pawn and you take his castle with yours.  So the puzzle isn't finding a way for your pawn to move forward.  But your coach is giving advice making you try and look for that. 

I've had this happen a few times now so I've just turned the coach advice off and I'm just going to try and find the best move and hope for the best.
