After move no. 57.Kf3 still it's winning for me?

I guess this endgame is winning because you're up three pawns. Your knight is trapped at the moment but you can just march the king up and get an escape square for the knight. I might be wrong though.

Yes, You have pawns Army. 🙂

1st move not bg1 1st move is bc5 maybe

it's black to move so black's idea bc5 and then kd7 got the knight

If Bc5 then Ke4 threatening to go kd5 if the black king moves?

Can't white play 69. b4 creating another passed pawn?

Black promotes first but white promotes with check and mates black

ok that mean it's winning right? 

at least that's what I think

ok
