No.743 by Vlaicu Crișan – Rundlauf of the black King combined with neutral AUW in Miniature! (JV)

Definitions:

n→Ser-#N: Black makes n serial moves and than goes Ser-#N.

PWC: When a capture is made, the captured unit (except a King) is replaced on the square the capturing unit just leaves. A Pawn is immovable on its 1st rank.

1. 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!

• Kjell Widlert says:

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.

2. Geoff Foster says:

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

• Geoff Foster says:

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] #

3. Luce Sebastien says:

Yes it is C+ only Winchloe with black pawn on f7 instead of g7

• Julia says:

Pg7 moved to f7 (agreed with the author).

• Vlaicu Crisan says:

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