The tourney was interesting. Many composers were managed to double of the theme. The problems with single performance of the theme claimed on high evaluation only if its had interesting nuances.

44 entries were received from 25 authors representing 12 countries | На конкурс поступило 44 композиции от 25 авторов из 12 стран
EN <-> RU

The following problems were excluded in view of full anticipations:
- No 11 (Kb3-Kb5), No 47 (Ke7-Kd5), No 48 (Kc7-Kd5) – yacpdb/20555;
- No 58 (Kf4-Ka5), No 86 (Kh4-Ka5) – yacpdb/152044;
- No 63 (Ka3-Kd5), No 77 (Kb7-Kb5), No 102 (Kg5-Kd5) – yacpdb/133163;
I didn’t consider the twin b) in No 17 because its actual play does not contain a required mate by Pawn. Also I didn’t consider the twin b) in No 18 because it coincides with yacpdb/216133.

1...Ra3+ 2.e3#
1...Ra4 2.e4#
Surprisingly graceful finding with two thematic mates: “direct” mate in threat and battery mate in the variation. Even promoted wB does not spoil the impression of the problem (but nevertheless the evaluation is reduced by one point compared with maximum).

Editorial: both authors independently sent exactly the same problem. So both composers considered the co-authors of it and every of them get 14 points.

Editorial: according the conditions of SuperProblem TT’s, only extra-set positions are not allowed (i. e. 2 Queens / 3 Rooks / 2 Bishops of the same color etc.), but promoted Bishop is allowed. So this problem remains in the tourney.

Main plan is refuted: 1.Sf7+? Kg4! 2.Rа3 Kh4 3.Kf5 Kh5 4.Rh3#, 2...Kh5!

There are quite strong anticipations (yacpdb/125572 и yacpdb/149717), but good key and elements of logics allow to evaluate this problem.
