I have received 31 anonymous problems: #5 – 1, #4 – 7, #3 – 23. Among them I selected 13 best, to my opinion.
I recommend an author of No 15 (Kb1-Kd4) to read the book «The Siers battery in the Bohemian three-mover» on Gordian’s site. A future of Bohemian problems is in moremovers.
The judge is ready in the future to regularly hold (1-2 times a year) such quick composing tourneys "SuperProblem" on the model mates, if they will be popular with the participants.

Award is the following | Отличия распределились следующим образом

Gravure. New interesting combination of mates in fourmover. There is partial anticipation by mechanism (yacpdb/65091), but it’s incorrect and with another mates. So I see no reason not to give this problem the highest distinction.

1st system of variation – model mates and reciprocal change of promotions in Khights.
As compared to yacpdb/264766, double threat is eliminated + 3rd variation is changed (criteria of originality by Rudenko). Additionally: pair of variations with promotions of the same Pawns in Queens.
A promising direction.
