Aleksey Oganesyan transmitted me 17 problems (one with 2 versions) in anonymous form.
Some defects I consider acceptable only with a sufficient content:
- key capturing a unit other than a Pawn: No 1B (Ke8-Kd6);
- checking key: No 2 (Ke1-Ka1), No 8 (Ke3-Kc5);
- unprovided check:
- No 1A (Kh4-Kf4) – Bxf2+;
- No 1B (Ke8-Kd6) – Sd7+, Sc6+;
- No 2 (Ke1-Ka1);
- No 8 (Ke3-Kc5);
- No 9 (Kf3-Kd4);
- No 10 (Kh8-Kf7) – Rxd8+.
For those problems, I considered the content was not sufficient and they were eliminated.
Some other entries were eliminated because the content was estimated too weak or not enough original (using known matrixes).
A general remark for selfmates with variations is that often are found some units needed for only one variation. This is tolerated in selfmates and directmates but would not be in helpmates. My feeling is that the technical level of the problem is more satisfying if the number of “one- variation-units” is limited.

The mechanism using white half-pin is known (see pdb/P1323107) but extending it in 2 phases with reciprocal change is an excellent technical achievement!

Having Pelle moves by White and by Black was expected for this tourney. With this feature, the problem could have been higher in the award, but the content is not so harmonious as in previous problems and there are technical weaknesses (1…Rxf5+ is “black dual” to 1...Qd5+; Bh1+Qg2 and Rg6+Re6+Pe7 are “one-variation-clusters”).

1...Rf3 2.Sb2+
(Sce5+?) Ke3 3.Qe1+ Rxe1#
2 harmonious variations with black and white Pelle moves. Would have been placed higher, if not the short threat.

1.Rc3! exf6 2.Sf5 fxe5 3.Re3 e4#
Funny with a mating Pelle move by a Pawn (and also a Pelle move by white Rook). Rather heavy. I guess the composer didn't use a Bishop on a2 because of Pawns e2 and g2 (“obtrusive” Bishop)

3rd Commendation - No 11, Frank Richter & Hartmut Laue (Germany) 1B6/3p3N/3q4/1RpQ4/1PR1Pk1p/2PK2nr/2PPB1pp/5brn

*1...Q~/Qe5! 2.Qf5+/Qf7+ S(x)f5#

1...Q~ 2.Qf6+ Sf5#
1...Qe5! 2.Qf2+ Sxf2#
1...c:b4/d4 2.Rf5+ Sxf5#
A Pelle key and 2 changes after unpinning Pelle moves, but the impression is schematic and the changes not very interesting.
