In the next diagram, the Black King stops the Pawn, but the White King aids it. Will the Pawn now advance? Far from it! I The King will first gain room for the Pawn by _Zugzwang_ and therefore use the Opposition.
White to move wins by
1 K-Q5
K-K2
2 K-B6 ...
Thus the White King has gained the power over Q7, a point over which the Pawn will have to march
2 ... K-Q1
3 K-Q6
K-B1
4 K-K7 ...
Now the white King also guards Q8. No matter what Black may do, the Pawn will safely advance to Q5, Q6, Q7 and Queen on Q8.
