Only one solution is given as correct but surely there are multiple equivalent solutions to this one. Can anyone demonstrate that there is one superior solution? [The puzzle ends when the pawn is promoted.]
Do you have a link to the puzzle? It looks like there is likely only a single solution, up until promotion, to me.
Sorry. I don't have a link to it. It came up as part of a Puzzle Rush and I could only screenshot it before it's lost to me forever. The reason that I think there a multiple equivalent solutions is that Black can use different configurations to get to g2 and f2 safely but I can see that without knowing how White responds you can't know.
Nevermind. I can see now that always leading with the Pawn is forcing whereas leading with the King isn't.
