Problem 735: Kostas Prentos - Helpmate
kostas.prentos(17.05.2016) Another nice original showing the WCCT-10 theme. Looking at the quality of this original, I am sure that this WCCT theme has been a success. Can't wait to see the entries!

Thank you, Rodolfo. The proposed version is indeed more economical. Since I don't have your email address to communicate in private, I will suggest the following arrangement with this comment: We can call this version either "KP+RR", or "KP, version by RR", your choice.

Kostas, you can choose at will since you've done most of the work. It was crucial to find the schema for the doubling of the theme by the bicolour Umnov effects.

OK. Let's make the new version a joint problem: K.Prentos & R.Riva.

A slight regret is that the alternative path of the black Knight to d4 is blocked now, but getting rid of the black cookstopper is probably worth it.

Quoting the Editor's comment:
"I am sure that this WCCT theme has been a success..."

I think he was too optimistic. Of course there are some nice entries for the E section, but also many inaccuracies, fake black batteries and poor content regarding the white play.

The most obvious inaccuracy concerns the E028: you can replace the bQg8 with bRook.
A misprint or an author oversight (and selectors of his country)?

The E011 is one of the best entries about white play, but it is possible save the Pc7 by moving the wB on f4. Of course even with the Pc7 it is by far better than most of the entries.

That was Quick Rodolfo! (to find the improvement for E11). As you mentioned there are many nice entries.
