what do you think ? Can white win ??? or it is draw ??? (white to move )
1.Kd3! Ke5 2.Kc4 Kd6 3.Kd4 Kc6 4.Ke5 Kd7 5.Kd5 Ke7 6.d3 Kd7 7.d4 and White has permanent control of the opposition and will soon queen the pawn and checkmate quickly.
I agree with cobra91
So you can see on cobra91's moves that the white king moves up in front of the pawn. That is vital. A common mistake amongst beginners in such a position would be to move the pawn. If white starts by moving his pawn he misses the win.
It's a win if the white king can get to c4, d4 or e4, which he can.
