Daily Puzzle - Retarded

If you promote to a queen it's a draw because of stalemate.
After you promote to a rook, the black king can move to g7, but the rook can escape the threat either by using the h file or the 8th rank.

Oh dear, you need to look at it again.
Promoting to Q results in stalemate.
Promoting to R results in a win for white.
Black cannot "block" the Rook.

I remember days where i was looking at the board and everything was completely alien to me. Chess had completely different feeling. Like everything in life there is nothing like the first/beginner experience.
Yeah, we've all been there, feeling frustrated at a puzzle for showing an obviously wrong move... or not accepting an obviously winning move.
Especially back in the days where you did puzzles from books, it was common to hear less experienced players complain that they often found alternate solutions heh.
