[Retros] Ke1 - g1 (Are the King and the Rook....?)

[Rol, Guus]

Thanks Roberto, I will look at the position. For years I have enjoyed solving the Christmas puzzle in one of our newspapers, for the main reason that there is always one error in it, two in the very good years. Nothing exceeds the satisfaction of finding the errors plus the solutions! Also, this will be last fortress to fall to the computer, a million years from now. One year ago I suggested to the belgium team captain to organize a solving contest based on the intentional error idea. I mentioned options like "omitting a pawn in the diagram", "changing draw to win in the stipulation", "mistyping helpmate for selfmate" (this one I encountered in a recent puzzle) - possibly in a mix with some correct presentations as well. For the requirement to be in special state of mind to solve these problems, I suggest the name "wodka solving contest" for such a competition. When you think about it, the whole concept is quite similar to MDR but projected in the domain of typographic and pictographic errors.

Guus Rol.

Hi Guus,

Here we inform the problem we were talking about:

Jorge Lois & Roberto Osorio
Peña del Mate de Ayuda- Buenos Aires

8/1pp1p2p/b1p5/1p4P1/PP4pb/QrP2PrR/BP3PPB/k5KR
How does this end?
Minimal Deviation from the Rules (MDR)

MDR is a modified convention to present a diagram (article under preparation) The basic idea is that the diagram MAY be illegal as the result of a last geometrically correct illegal move. Then, retraction 7.4 of the Laws has to be made and assume the art. 4 consequences.

This way, nothing has to be explained regarding fraction of move when presenting the problem and the solutionist has to find by retroanalysis all the details.
Article 4.6 forces white in this problem to mate by O-O.
A traditional presentation of this problem would be #0.5, but obviously this is much weaker than the MDR alternative.

Best,
Roberto
