We received 62 entries in anonymous form for this tourney, some of them in two different versions. The large amount forced the judges to examine about 250 positions, but the work was pleasant and interesting, given the variety and quantity of ideas.
A few remarks relating to proposed twinning theme: it is not new, but was seldom used by composers, perhaps never as theme in a competition (thanks to V. Nefyodov for his advice).

[Editorial. In 1994, in 12-13th issues of Russian magazine "Интеллектуальные игры" ("Intellectual games"), Vladislav Nefyodov & Nikolay Vasyuchko have published the article "Конец это только начало" ("End is just a start") about some different types of continued twins which are formed from mating position of previous twin via shifting or changing color/type of mating piece. Among all problems in that article, there were four Vasyuchko's problems which are thematic for TT-174: yacpdb/418092, yacpdb/418093, yacpdb/418094, yacpdb/418095.
So, perhaps there were first problems with continued Forsberg.

Participants created Forsberg twins in two ways, both permitted:
a) each twin always had a different Forsberg piece;
b) at least one twin reused a Forsberg piece already used in a previous twin.
This different rendering produced excellent results and the level of the tournament is very satisfying.

A few words about our criteria of evaluation when judging:
- unifying idea. As the proposed theme was not difficult, an idea that binds the twins together unifying them - a theme inside the theme – is a must for a high ranking;
- economy. Good economy, i.e. light, clear positions, is also important. Above all, the pieces should preferably be active in all variants, especially the white ones;
- originality. Some entries matched the theme with other ideas (for instance: perpetuum mobile, repeated manoeuvres, double solutions, retrograde analysis etc.) thus creating pleasant problems.

We had to exclude as non-thematic the following entries:
- No 16 (Kd5-Ke1) – promoted wS in b);
- No 45 (Ka5-Ke3) – promoted wB in a);
- No 4 (Ka8-Kf6) – stipulation h#1.5 (h#2 was required);
- No 2 (Kg1-Kd1), No 43 (Kg1-Kh8) – multiple Forsberg pieces in at least one twin because of mate by double check in the previous variant.

And partially exclude the following, because of one non-thematic or dualistic twin (which also makes all following twins obsolete):
- No 5 (Kh8-Ke3) – e) is non-thematic;
- No 10 (Kh1-Ke4) – d) is dualistic;
- No 36 (Kc2-Ka8) – d) is non-thematic.

We finally decided on the following ranking (see below). We want to thank all participants, awarded and not awarded, for all their entries: they made this tourney a success for participation! And of course we want to thank the tourney director Aleksey Oganesjan for his perfect organizing and his help to the judges.
Thanks and congratulations to everybody!

1st Prize, 1st Place - No 31, Emanuel Navon (Israel) 4b3/4rp2/3p4/1p2pB2/1Pk1Pn1Q/2P1pP2/4P3/6K1

a) diagram: 1.Sd5 exd5+ 2.Kxd5 Qe4#
b) mating position of a) wRe4: 1.Re6 Rc4 2.bxc4 Be4#
c) mating position of b) wSe4: 1.Bc6 Sd2 2.exd2 e4#
A very difficult, original and most elegant way of showing the theme. Mate on e4 in all phases, and also Forsberg-twinning on this square, plus sacrificing the Forsberg-piece on the first move in each phase, and then mating with another piece on the same field! A thematically excellent, very powerful and beautiful performance, well worth a 1st Prize!

2nd Prize, 2nd Place - No 61, Evgeni Bourd (Israel) 6K1/pP4b1/Pp6/Ppk3rq/1prn1n2/8/b7/7B

d) mating position of c) wSc6: 1.Rc4 Sd8 2.Sd4 Sb7#
e) mating position of a) wPb7: ... perpetuum mobile
The tourney featured several Perpetuum Mobile problems - but this is definitely the best one! It contains a full Forsberg-set in the twins, and also most ingenious play by Black, who must block d4 by the Knight or the Rook alternately, depending on the mating piece, while being careful not to put the White King in check. Another most impressive entry, well worth a Prize!

3rd Prize, 3rd Place - No 26, Fadil Abdurahmanovic (Bosnia & Herzegovina) B3K3/n1P5/k2bn3/4p3/1rpq4/8/8/8

a) diagram: 1.Sb5 c8Q+ 2.Ka7 Qb7#
b) mating position of a) wPb7: 1.Kb6 b8S 2.Kc5 Sd7#
c) mating position of b) wPd7: 1.Bc7 d8B 2.Kd6 Be7#
d) mating position of c) wPe7: 1.Sf8 exf8R 2.Qc5 Rf6#
A very nice, original AUW, in a very light position! Very clever use of the theme! One small weakness is that it is not perfectly homogenous: in d), unlike the other variants, the Pawn promotes by capturing a piece. Also, it had been very nice if the Forsberg Pawn had been moved one step to the right in each twin (i.e. b-c-d-e instead of c-b-d-e)... Still, it is another very impressive entry, and another most worthy Prize winner!

a) diagram: 1.Qb3 Bc2 2.Bc3 Bd3#
b) mating position of a) wSd3: 1.Rxb5 exd4 2.c5 Sxe5#
c) mating position of b) wRe5: 1.Ra5 Rd5 2.b5 Rxc5#
A very fine, homogenous way of displaying the theme: Tempo moves by White and Umnov + self-interferences by Black in all variants! Maybe not quite as original as the first three places, but still a very powerful implementation of the theme, and a well-deserved Prize!
EN <-> RU

5th Prize - No 59, Ilija Serafimović (Serbia) 8/5N1r/8/3P1k2/8/4b2P/1q1Pn2K/4nr1B

c) mating position of b) wPg3: 1.Re4 Kh1 2.Bf4 (Sf4? Rf4?) g4#
Very nice play by black, with 3 different self-blocks on f4! Also a relatively light position. A little sadly, though, the author did not manage to use a Rook as a mating Forsberg piece in c) - that would have resulted in a most impressive cyclic combination of self-blocker and mating Forsberg piece (S/B - R/S - B/R)! Still, it is a very good implementation of the theme, and another well-deserved Prize!

g) mating position of f) wPc6: 1.Bd6 e5 2.Be7 c7#
7 model mates plus full Forsberg set is a respectable achievement, but no clear common theme binding the variants together, as in the Prize winners; that is why we rank it a little lower.

A fine minimal in a light position, with a nice, funny use of the black bishop, which goes like a pendulum between f3 and a2, as it is used as a blocker for the rooks in 2 variants and a self-blocker for the king in the other 2.

2 different branches in the twinning (the same idea was followed by No 19 and other compositions) and also model mates in all of them; economical position too, but perhaps not that advanced play.

b2) mating position of a2) wPc3: 1.Bc2 Bb4 2.Bd3 Sd2#
Another entry with 2 branches of twinning. This one, though, does not feel quite as balanced as the previous one: the play in a) is good, with 2 pin mates, one with each piece in the original half-pin as pinned piece, but the two twins have much simpler play.

d) mating position of c) wRd3: 1.Sxd6 Rf3 2.Sb7 Re3#
Black performs several self-interferences: the idea is rather advanced and nice. A little inhomogeneous though: in a) and b) Bc1 and Rf5 interfere each other once per variant, but in c) and d), there are two completely different interferences; the position is quite heavy.

Special Honorable mention - No 44, Andrey Frolkin (Ukraine) & Chris Tylor (England) 8/4p3/6np/4pp1k/4p1np/4p3/6KP/3N3r

The theme definition has been modified to involve retroanalysis: in twin b) the mating piece is substituted for by a white piece in such a way that the resulting position is legal, all other substitutions leading to illegal twins.

a) diagram: 1.Kg5 Sf2 2.Kf4 Sh3#
b) in the mating position, change the type of the mating piece to produce a legal position:
wRh3 (last move: Rg3-(x)h3); if the mating knight is replaced with a white queen and White retracts - 1.Kg1-g2 followed by -1...g2xh1=R+, black pawns will have to have made one capture too many.
1.Kg5 Rf3 2.Kh5 Rxf5#

This entry does not define the type of the Forsberg piece in b), thus adding a plus of retroanalysis to the theme. Very original!
