Here’s an end game that really bothered me for 15 mins.
After 10 mins of struggling with it, I realized that I have to let go of the pawn to win. So I have to win this with a king and rook ending.
The moves I finally came up with
1) Rh1 Kd7 2) Rh7+ Kd6 3) Kc8 Rc2+ 4) Kd8 Rb2 (It has to, since any other move will advance the pawn to a queen) .. 5) Rd7+ Ke5 6)Kc7 Ke6 7) Rc7 Rf2 8 ) b8 Rf8+
