The concept of changed blocks became very popular in chess composition as a convenient and explicit way to design relations between sets of pieces. Contrary to blocks, observations - including guards of K flights - require a deeper ("secondary") analysis by nature as they involve the pieces' forces represented by invisible lines rather than their eye-catching masses. This substantial difference may serve as an explanation for the experience of a widespread tendency to overlook, underestimate or mistrust shifted guards even when presented in extended cyclic fashion. The invitation to suggest a new tournament theme was a welcome occasion to address that maladjustment, and I did not hesitate to launch a sincere attempt to improve aesthesia in that respect. Thanks to the SuperProblem project team for providing that opportunity and to the participants for having contributed to a valuable input including some major achievements, especially when it comes to Letztform presentations! Maybe the time frame was too tight (and/or my definition too sketchy?) to unearth others - like the (most probably) first embodiment utilizing variants of a direct mate problem - but it does not seem overconfident at all to predict that the last word has not yet been spoken.

I am aware that any award must be subjective by nature, but for once I feel the need to put my judgement into perspective, as I am afraid that I could not stay unaffected by the following two considerations in spite of them clearly being matters of personal taste. Whereas the outcome confirmed that it does not hurt to allow additional non-thematic guards for thematic pieces, it became obvious that I struggle with problems not showing model (stale)mates (or in other words: pure guards) in this context, at least when it comes to cooperative play. I had to look outside the tournament to find examples hot enough to light my fire (see yacpdb/90944 & yacpdb/383283). My apologies that I missed to warn you before, but I did not foresee this in its rigorousness! Feel free to benefit from the formal character of the tourney and find an audience that shares your personal gospel.

Almost all contributed problems (21 out of 23) are helpmates. None of the others made it into the award. Let me provide some details below without spoiling too much (K positions in parentheses):
- No 2 (Kh8-Ke5). Only one of the three mates is model - watch d6 in Sc4# and f4 in Bd6#!
- No 4 (Kc4-Ka5). The arrangement of stipulation and phases proved unique in the tournament, but the idea loses momentum with pseudoidentical mates and the fairy pieces have an unpleasant technical appeal;
- No 5 (Kg1-Ke6). The twinning replaces a thematic piece, but still the b) mate is not pure (Pf6!);
- No 7 (Kh1-Kd5). Move Pf2 to g3, shift position one row downwards, put the wK on b8 and remove Pf4 for the perfect realization of a nice problem;
- No 13 (Ka8-Kd5). With Pb5 destroying the model mate in Be4# the problem looks unfinished to me;
- No 15 (Kg8-Kd4). It is a pity that the highly original setting does not provide a model mate in b) (watch e3);
- No 17 (Kg2-Kc4). Three line pieces change their roles covering all the rows of a mirror model mate, kicking in the front door to form the full cycle I barely dared to dream of when I launched the theme. This wonderful problem would have shared the 1st Prize, but to my surprise the crown jewel among the tournament's treasures is fully anticipated by the masterpiece shown in yacpdb/383284! Please compare to the fairy variation recently published in Die Schwalbe 2/2015 (yacpdb/383285), too;
- No 18 (Kd7-Kb5). Evidence exists that this great idea can be done with 1 fairy + 8 orthodox pieces and pure stalemate positions;
- No 19 (Kh7-Kd4). With wPc5 instead of bPc3 and b) c4->b2 the only tourney example involving a set of four thematic pieces would already be equipped with model mates;
- No 23 (Kg2-Ke6). If the 1st black moves would be as homogeneous as the 2nd ones (compare to yacpdb/383286), the little brother of No 17 would have gained some sweets.

The q/s epaulettes complementing the rows attacked by the pawn deliver convincing evidence for the beauty of an unbalanced square count as previously conceived in a much more bumpy setting (see yacpdb/351041). The demand for an unambiguous role assignment is satisfied on the fly, keeping the material on an unbelievably low miniature level.

With both the reversed order of black moves and a subtle separation of thematically independent mating moves perfectly integrated into a pattern of apparently disparate flight pairs a non-standard mating net based on the famous couple of Dawson's classical fairy pieces G + N induces the tourney's best "standard" (=2x3) presentation. Pc5 is the only member of an inconspicuous set of cookstoppers justifying a (very) gentle lament.

Concentrating on the contrast of activities - all thematic pieces move in the first solution and only one per team in the second - this time the alliance of cycles even gets along without any additional piece.

The split into two separate Platzwechsels is a welcome enrichment to the cyclic shift of blocks previously explored (e.g. in the announcement's first example). The ideal mates suggest a Letztform here, with nothing but an additional P guard preventing the minimal piece count.

The borderline twinning requires a special treatment, but cannot challenge a theoretical achievement of historical dimensions. The full cycle (compare to yacpdb/383288) is already covered by a), f) and e). The additional twins add all the missing variations to complete the full set of permutations.

The third installment of a well-tried gear (see 3rd-4th Prize) combines the double pawn flanked by the S with a simple, but effective block change driven by the need to unguard the mating square. This mechanism requires a little more material as it leaves one black piece per solution fixed on its remote diagram location and fails to assign a guarding task to the wK, who nevertheless is used quite well to avoid duals. Note that it is possible to deploy another bR instead of bQ (6r1/8/8/2r1S1p1/1S3kP1/1K1P4/3P4/8) as demonstrated in the 4th Commendation, but the benefit would be debatable here.

Enabling parties to move the opponent's pieces, the Platzwechsel Circe condition is a perfect tool to speed up the thematic shifts, and it is no surprise that among all fairy elements this one was favored by competitors with a total of 4 applications. I suggest that the result still did not live up to its full potential, but this very economic (if slightly mechanical) realization of a specific echo model mate is already getting far.

Of the two helpmates using set play to incorporate two ideal mates (compare to 1st Commendation) this one exhibits the more interesting manoeuvres. Even if you might deem the author's label 'bicolour anti-Argüelles' a little magniloquent, it is fun to see how the bQ must cope with Pb4 in order to block the square left over from the pair guarded by Sb3 in the other phase, spotlighting both the lower edge of the board and the line a7-f7.

4th Honorable mention - No 10, Dieter Müller & Franz Pachl (Germany)

a c5/d4 d6/e5 e4/e6
b e4/e6 c5/d4 d6/e5
The bR transfers Bf5 to f2 for a reason, whereas the bP is (passively) transferred to g3 'by chance'. So it is not the 'cyclic shift of pieces' (which is rather cheap in Platzwechsel Circe, by the way) but the clean shift of three flight pairs and the cute tempo move that advocates the problem's inclusion into the award.
Обмен местами черной ладьи на f2 и белого слона f5 мотивирован, в то время как пассивный обмен местами на g3 и f2 «случаен». Поэтому здесь не «циклический контроль фигур» (который довольно прост в Platzwechsel Circe, между прочим), но чистый контроль трех пар полей и привлекательный темпоход, который оправдывает включение задачи в присуждение.

This Grimshaw-like dual avoidance scenario was the hardest entry to judge, as technical considerations (determination of move order) seem to be the main impetus for the use of fairy pieces (PA+VA) instead of R+B. However, I failed to get by with orthodox force without sacrificing significant content [1q6/2S5/8/8/spk5/8/P1r1P2K/3S4], so the benefit of the doubt applies.

Two different pieces (B+S) being partially unburdened by the blocking piece make for an interesting alternative compared to 3rd HM. The full use of the pawn double step adds to a well-rounded result. The good overall impression is weakened only by the repetition of the initial black move, most likely evoked by the choice of the blocking piece's type.

In a narrow format like this (and with the acting rook destroying the ideal mates!) the Platzwechsel Circe trick comes across as a little too blatant. A second specific mate certainly would have soothed the misgivings.

With similar pieces blocking on the same square the overlapping routes may as well be regarded as a plus, but there should be no dissent about the requirement of additional pawns and a twin. However, this variation of the idea also shown in No 8 (1st-2nd HM) deserves to be remembered.
