EN <-> RU

From TT Director I have received 37 anonymous problems including 1 version. The TT theme was the impetus for new opportunities of realization of basic form of Chumakov theme. This allowed the authors of some problems to demonstrate their high quality.
Unexpected loss: No 18 (Kd4-Kd6) was non-thematic.

Rest 36 problems were divided into three subsections – by type of mating finals and by quantity of thematic black pieces:
1) ideal mates (6 problems);
2) non-ideal mates, three black thematic pieces (21 problems);
3) non-ideal mates, four or five black thematic pieces (9 problems).

Such division is explained by the expediency of evaluating problems related to the thematic content (in relation to sports terminology – problems belonging to one or another weight category).
When evaluating tasks, attention was paid to the implementation of the theme, although other points were not left without attention.

I thank the TT Director Aleksey Oganesjan for clear work and the authors – for effective feedback on the theme of the competition.

Award is the following | Отличия распределились следующим образом

1st Commendation - No 31, Ivan Antipin (Russia) 3kb3/1K1pqr2/3b4/4pp2/8/6P1/8/8

a) diagram: 1.f4 gxf4 2.Bc7 fxe5 3.Qd6 exd6 4.Re7 dxc7#
b) Kb7->h6: 1.Qe6+ Kh5 2.Ke7 g4 3.Kf6 Kh6 4.Be7 g5#
Minimal problem – gravure with model mates. 4 thematic captures (3 active sacrifices), 4 blockings. FML in both phases. Pity that a play of thematic piece in the twin does not allow to evaluate the problem higher.

In 1st phase – 4 active blockings, in 2nd phase – 4 passive sacrifices are supplemented by functions permutation of bPg6: sacrifice – using for blocking. Model mates. Pity that a repetition of 1…Bc6 does not allow to evaluate the problem higher.
