Endgame Study #4 + Update!

Hello everyone, I've decided to make these endgame studies a daily thing! Just like the daily puzzle, I will post one endgame study everyday (hopefully in the morning)! Hope you guys are enjoying it, here's a bonus study for today . It's a very interesting position where white is up a rook but black's passed pawns make it so that white must come up with a very clear-cut solution to win! 

Hope you enjoyed it! Make sure to check out my other blog posts, including other endgame studies! (you can find them on the side panel of my blog)
