This nice study is short and illustrates a big theme of many endings, promote the pawn at all costs. Here the question is, how to do that?

It's a nice study. Note that, to win, you would have to be able to win the Q vs R ending... no easy feet against a good opponent if you haven't studied it.  ;)

a good study.

Nice one PfromB

Very astute observation :)

After Rc4 in the final position how should white continue?

displacement of Rook

I easily solved it

The study isn't difficult to solve, but if you do this in a real match, you still can have a though one on it.

Good illustration. That's the first puzzle I got right. 

The solution is incomplete because the solution does not contain analysis to cover another rook move. 

What is missing is 1.e7 Rb8 2.Ra6+ K-any 3.Rb6+ Rxb6 4.e8=Q

Good one.

That line was covered. It is in the move list if you look back at the study.
