Problem 506: Zivko Janevski - Helpmate
zivko.janevski(23.01.2015) Black correction in helpmate? After all, black is helping, one assumes. Well... Zivko Janevski demonstrates it is possible!

I suppose it is a wrong diagram :-)

Yes, Vitaly, there was wrong diagram for few hours, but now it's OK. Thanks.

It is almost Ok now. One more thing - the number of black units must be 8.

Quoting Vitaly Medintsev:

You are right of course :eek: ! Done. :-)

Here is a problem by Dieter Muller. It is interesting to see how the same mechanism can be used for quite different effects.

I think I should refrain from commenting since I'am the judge but I would suggest to compare Zivko's H#2 with the following one:

In my opinion these three problems - the Original by Janevski and other two in the comments have different thematic content even that the schemes are similar.

Boettger & Koelske's helpmate is clear strategical with harmonic two solutions.

Mueller's is nice 2x2 HOTF with rich content (but no gate-opening).

Janevski's instead of 2 or 2x2 thematic connected solutions have 3 solutions with paradoxical logical effect - the bS "random" move make possible the mate in the 1st solution which is prevented in other two solutions. Nice correction effect, unusual for helpmates. All three solutions are thematic connected by the gate-opening from the bS and three selfblocks by the bPs.

All these three nice helpmates have their own pluses and in my opinion can exist as originals.
