In this position I was Black against an IM and I was fine with a draw during the game but was also looking for some small winning chances if they existed. Obviously, the first thing you need to calculate is the king and pawn endgame. Black has an outside b-passer which White will take, but only by spending valuable time with his king. However, is this time enough for Black to infiltrate with the king and create winning chances if White goes wrong and maybe a draw with accurate play? Or would White hold his pawns and win the resulting endgame? The endgame is pure calculation and would be helpful if you want to improve just calculation. King and pawn endgames are tricky!
I spent about 20 minutes calculating the consequences, and went into the complications. I knew that if I played something like Kf7, the game would almost certainly be drawn without much thought required from either side. However, after trusting in the calculation of my lines, I "yolo-ed" and went for it.
