Lucena End game

Sort:
remusac

Was watching GM Friedel's endgame video (https://www.youtube.com/watch?v=7EYY0JCuAlY) and he reached the position below. I don't understand why black can not draw with rook takes on B7? 

[Event "?"]
[Site "?"]
[Date "????.??.??"]
[Round "?"]
[White "?"]
[Black "?"]
[Result "*"]
[SetUp "1"]
[FEN "8/1P6/2K1k3/3R4/8/1r6/8/8 b - - 0 1"]

Yes, if you look in the comments, there are at least 20 people pointing out that mistake at about 36:56 into the video.
