I can add that it is also easy for humans to see that white can force repetition

White only need to prevent the black king that is the only piece that can move
to go forward and it is easy to see that white can do it.

It is easy to construct a table that gives for every square of the black king a
square of the white king and prove that white has at least a draw.
