I didn’t see that. Yikes!
step 1: Kf4, getting off the f5 with tempo as black will queen on b1
step 2: then b4, and so a4 will queen
valuable insight, crystal clear on the explanation. Thank you.

Glad to help.
1.Kf4 also takes the rectangular opposition.
It has absolutely nothing to do with opposition.
Black is too far away from the a-file to stop the a4 pawn, while white is missing just one move to stop the b4 pawn. And white is doing just that: 1.Kf4 Kg7 2.b4 axb4 3.Ke3 and the a4 pawn will queen, while the b4 pawn isn't a danger now (as per #2).

Thank you for clarifying the opposition, I am still working on the definition and purpose of it in Silman’s endgame book?
Could you also please clarify the last part of your last line: “as per #2”
I was trying to figure out the part on the pawn isn’t a danger?
Insightful
White to play:
Could someone please, please explain this pawn endgame or opposition?
I had first tried working with g3, then g4.
All others b4, or Kxf6 fails obviously.
Gave up and ran this on Fritz, and it’s Kf4? Is this the opposition part? Taking the opposition?
Thanking all in advance for your kind comments and enlightening inputs. Bless.
