This was the game and we got into a rather mental endgame. I was able to grind out a win, but needless to say there were plenty of issues with technique on both sides.
I think with correct play this should have been a draw. So what I want to know is that are these positions theoretical draws? Or was it always a winning endgame that got drawish because of inept play from me.
If so what is the correct technique/principle in winning endgames like this?
