Does black have to avoid quicker mates without a pawn (e.g. best play) or can he move Kh8 after Rg6+ for example?
This means that Black need not worry about shorter mates that do not involve a direct pawn check.
Originally posted by SwissGambitThat's what I would have wanted to say too, but I could not. Another annoyance is that if you have several King moves on move 5, 11 and 16, you'd have to work out a lot of variations... I suppose the path towards d2/e2 is semi-forced for the Black King and after that all is forced (or maybe totally in the ending the King can choose two squares with two different variations, but I suppose not)

Originally posted by crazyblueYes, white to move and mate with the pawn on move six.
Is the 6th move also mate? Because it already seems won in the current position 😉
I literally copied the description that went with the diagram, to avoid confusion (since I didn't totally understand it as well).
