Nice series problem Vlaicu! The diagram seems incorrect, though. It is C+ Popeye v4.61 with bPg7->f7.

With bPf7 the “cook” given by Popeye v4.63 etc is also quite entertaining!

I suppose the problem with the diagrammed position is the dual 3.Kf7/Kd7 in the first solution? A real problem, yes, so the diagram does seem wrong.

There is at least one cook that can’t be fixed: in the second solution 6.Bxd7(+nPe8=nQ) works just as well.

Sorry, please ignore my earlier post. The nPe8 is a captured black pawn, which would not promote on e8!

Agreed! I was referring to: 1.Ke6-d7 2.Kd7*d8[+nPd7] 3.Kd8-e7 1.nPd7-d8=nR 2.nRd8*e8[+nPd8=nQ] #

Thank you very much, Julia!
There is life for neutral pawns on the 8th rank, isn’t it?
