Missed opportunities in a 45 45 with NRTG
I'm usually pretty decent (for my level) at endgames, but today I made a lot of errors in a very even endgame and ended up with a draw. In my defense, this seemed like a more complex endgame than I'd seen in a while, and I couldn't remember the principles to follow with a KRP vs KR when the pawn is on an edge file. I made plenty of calculation errors in this game, but none of them are super obvious. In fact, I need to study this some more, because there are many positions here I still don't understand.
