White to move

Does anything change?
The original version of this endgame problem appears in Capablanca's Chess Fundamentals, and likely other places before that.

Yes. But I wonder what the aimed 'change' is. Still haven't found it.
In the new position, I still don't see how black can prevent white from winning, so I guess I'll have to answer that nothing changes. If black has a trick up his sleeve, I'd sure like to see it.

Originally posted by range blastsUsing the diagram in the OP's post, white begins with 1.g6. Black has to capture the g6 pawn, otherwise white will just capture on f7 or h7 and promote on the next move. So, black has to play either 1...fxg6 or 1...hxg6. Let's assume black plays 1...fxg6. Then white plays 2.h6. Now, regardless of which white pawn black captures, the other white pawn will promote.
so how does white manage to win? I do not see it, other than a draw 😕
Edit - And as far as I can tell, if black tries to push the b-pawn closer to promotion, once white promotes a pawn to a queen, the queen can fork the black king and b-pawn.
