Endgame!

It's been a while since I've played an end-game. I had an opening advantage, which I converted into a difficult late middle-game/early ending, which I converted into a positive Bishop V Knight ending where it felt like black had an advantage. Didn't stop it being a really tricky 'race' type situation where one wasted tempo lost the game. 46. f4! was more accurate than 46. Ke3? As for the opening, watching all those Hjorth videos helped a bit with the e5? g5! idea. (Jamieson - Hjorth, King's Indian Attack 1979)
