Why do you take the draw as black? You were in a winning position and could have promoted the pawn to a queen and therefore won the game

the win was thrown away.

How is that a winning position? White will just move between B1 and A1 hoping to force a stalemate on A1. If Black tries to corner White with the King, White can take the pawn.

Omg what did I just see :D

#5 on move 81 Kc2 would have won the game for black

Oh, so it would have. I was just looking at the final position.

I've played several games like this, from both sides. It's taught me to never resign endgames at my rank; both I and my opponent are perfectly capable of screwing everything up!
