How can white win the position on the left? Should white push forward the f-pawn first, then rush the king to the a-file to capture that black pawn on a5?  Or should white start by rushing the king towards the a-file? Before you decide which course to take, look at what would happen in each case. The first possibility would not force the f-pawn to become a queen because the black king will block it. What about the second possibility? If white moves the king to d5 and continues towards that black pawn on a5, the black king cannot stop that capture. And if the black king moves much towards the left, that f-pawn will advance. There would be no way for the black king to stop both white pawns. Is it possible for the black king to capture the f-pawn and still get back in time to prevent the queening of the white a-pawn? Look at the details below.
The only way for white to win is to rush the king to the left, to capture the black pawn. The black king will then be so much diverted in capturing the white pawn on f4 that it will not have time to later get to the upper left corner of the board to prevent the white pawn from becoming a queen. Prepare for that coronation. Look at the details on the right.
1) Kd5    Kf5        The f-pawn really must be captured. 2) Kc5     Kxf4 3) Kb5    Ke5       Now black must try to block the a-pawn. 4) Kxa5   Kd6      This could be close. 5) Kb6    Kd7 6) Kb7    Kd8       Nothing else works for black. 7) a5      . . . .        White wins with a pawn promotion.
