you run at the a pawn with the king then hike up to c7 pawn

Black can protect the c7 pawn with his king.  I was thinking after scooping up the a-pawn, going back with the king to try to scoop up Black's kingside pawns, but then if Black's king advances too far toward those pawns in an effort to protect them, White can play Bb6! when whether Black captures or not, White gets a winning passed c-pawn.

study the endgame and you will see black can't protect the c7 pawn because of opposition. I'm going. its called positional zugzwang

Yes, the answer is a line such as this: 

1. f3  a4  2. Kf2  a3  3. Kg3  a2  4. Kxh3  a1=Q   Kxg2 and the position is an absolute draw.  And the chess engines show [at the end] Black is winning.

This position and another position was given before by a grandmaster for chess.com.  I know this is bragging but am proud to say I found the solutions for both positions in about 10 minutes per position. So, sometimes a Septuagenarian can solve [some] chess positions better than the chess engines...

What for? The bishop can never take that pawn since the g2 one queens. The whole plan is not applicable, e.g. 1.f3 a4 2.Kd2 Kg5 3.Be3+ Kh5 4.Bg1 (forced) 4...h2! (vacating the h3 square for the king) 5.Bxh2 Kh4, and Black wins.

The g1 bishop doesnt move but to create reciprocl zugzwang. King picks up a pawn and promotes c pawn. Best chance, unless you want a draw!

not sure of the move order, possibly gain a tempo by playing f3 at some point!

Correspondence Play--ICCF US

 

Engines are allowed and used in ICCF US play. Playing, using chess engines as a help is sometimes called "Centaur Chess" At the highest levels of play--this kind of play is a search for the truth. Sometimes the play can be of a higher quality than of even some supergrandmasters.

 


 

Isn't that like using a dictionary at a spelling bee?
