Two-Rook Endgame, aka Heart Failure 101

 

Endgames and tactics are my two weakest points, so as you can imagine, an endgame with both the rooks isn't my happy place. This was an intense endgame in which I ultimately got the better of ram_oldfox, but it highlighted the sharp nature of rook endgames and how accurate play is needed. I've tried to analyse it as much as possible, but do comment if you have something that I missed.
