13 years ago... or: better late than never
Referring to Miodrag Mladenović's excellent article "Reciprocally Changed Variations in Threemovers (1)" published 13 years ago on the very first (Spring 1994) issue of Mat Plus, I would like to comment (after a long wait) about an inaccuracy regarding example no.11.
On page 24 Misha writes about Rudenko's no.10 (p.25): "... it is the only (one) of three examples with complete block in set position." This is wrong, as no.11 (p.25) is a complete block in set as well. Moreover, it shows the "right" order of phases where the primitive captures occur in set and the more sophisticated non-captures appear in solution. Of course Rudenko's problem should be appreciated for its amazing economy and the valuable threat in solution.
By the way, while composing no.11 I had no idea of no.10.
Here are the 2 problems:
