Section H#2 | Задачи на коопмат в 2 хода

First of all, I would like to thank the editor for giving me the honor of judging this tournament on the SuperProblem site and also for the collaboration, having reported several compositions to be compared with the published ones.

69 helpmates in two took part the tournament: the general level was good enough but lower what I thought.

List of participating problems : E401 (E401a), E402, E403, E405, E406, E408, E409, E410, E415, E416 (E416a), E417, E422, E424, E425, E428, E430, E431, E432, E433, E436, E437, E439, E448, E448a, E450, E453, E454, E457, E460, E461, E465 (E465a, E465b), E469, E470, E476, E477, E478, E480, E481 (E481a), E482, E483, E494, E496, E525, E526, E530, E534 (E534a), E535, E536, E539, E542, E543, E544, E551, E552, E553, E554, E556, E557, E559, E560, E566, E567, E568.

Before moving on to the ranking, it is right I motivate my choices with comments on some of the problems I did not selected. Regarding others not mentioned below, I think they have a too simple or unbalanced content.
E403 - Improvement of a problem by the same author: ycpdb/361341. I see enough differences to justify the publication, but not for recognition.
E408 - This HOFT is enjoyable, but the four solutions are simple.
E415 - This problem has certainly deserved the publication for the presence of the 4 bR moves in B1, but there are many similarities with the helpmate of the three co-authors (see ycpdb/384875), of which is obviously a version.
E422 - Tempo move only in one solution.
E428 - It doesn’t convince me. Three pairs of solutions, each pair with simply the inversion of black moves and identical play.
E430 - The solutions are rather similar.
E432 - Familiar mixed AUW.
E436 - White promoting pawns are used in turn. I prefer the CJ Feather problem published together with the solution.
E437 - Linear content with concurrent mates.
E450 - Symmetrical.
E454 - The strategy is rather familiar. Despite the dual avoidance, the black inversion of moves it’s a simple mechanism, in my opinion, which produces two identical mate positions. The extra solution has only a few elements in common with the first two (selfblock, battery mate) and it doesn’t increase the problem value.
E457 - Well known strategy in twin form.
E460 - Nice but familiar Grimshaw and concurrent mates.
E461 - The position is legal also with a bPe7 for the bSf7. 6bq/1p2p3/1p4Q1/bp2N2p/nkpK4/p1p5/2P5/8
E465, E465a, E465b - A possible improvement of economy: b7/4Brpn/3b2kN/R2N2pp/5P2/8/8/7K
E470 - Anticipated by Árpád Molnar, Magyar Sakkszövetség 1965, 3rd HM (see yacpdb/44471).
E476 - The part a) is acceptable, with Zilahi, Kniest, distant blocks, but part b) is rather symmetrical and schematic.
E478 - The effects in the wPP moves are not really attractive and the content is rather unbalanced.
E481 - Unbalanced, improved by the version.
E481a - The battery play is familiar.
E482 - Version by Vidadi Zamanov, Wola Gułowska 2016-12, Comm. (See yacpdb/422655)
E525 - The bQe8 can be removed.
E530 - I think this idea should be developed without the black interferences in B2, to avoid so the use of the two BB in turn.
E539 - Can be compared with yacpdb/444282 and also with P1269818
E544 - It would have been better to develop this idea in 3 moves with two solutions.
E551 - Nice miniature with two Anderssen mates in the same square, but I think it’s a little bit for a recognition.
E553 - The mates on the same line feel simple. The strategy can be compared to P0577761
E557 - In my opinion, the announced cycle did not succeed well, because the move in e6 is always in B1 and that in e5 in B2.
E559 - The Zilahi matrix is like the following: yacpdb/404403
E560 - Substantially the same matrix of Christer Jonsson, ASIGC 2011-12 (see yacpdb/404253), with two more solutions.
E566 - The absence of castle in d) takes away all charms.

A very elegant HOTF problem, which shows a duel where the wQ is opposed to a bS and to the bK, in diagonal-orthogonal echo. In two solutions the bS interferes one of two white pieces, while the other moves in W1 in turn, for a nice ASP play, obviously with pin mate. In the other two solutions the bS captures one of the same white pieces in turn, to open so a flight to the king.


2nd Prize - E542 Christer Jonsson (Sweeden) and Rolf Wiehagen (Germany)1q2n3/8/3n4/4Kp1r/2P4p/2pQb3/8/4r1k1

   } c) bKg1-->b6 1.Kb6-a5 Qd3*d6 {(Qxe3? 2.Qb4 Qa7#??)} 2.Qb8-b6 Qd6-a3 #

This problem stands out for the cyclical dual avoidance for white selfpin, followed by direct unpin of the wQ with selfblock. The cyclically changed functions of Qb8/Re1/Rh5, the black FML, and the model mates are very appreciable in the whole. Pity the two choices in c) involve different mates, so there is not the cyclical form for those. The helpmate P1343384 reported for comparison is very complex, with once again three wQ moves. However its strategy is different from that of E542. In that problem every promotion allows a different selfpin move by the wQ, then the promoted piece unpins the wQ.


3rd Prize - E526 Michal Dragoun (Czechia), Ladislav Salai jr., Emil Klemanič, Ján Kovalič (all three Slovakia)Rrq2k2/n5p1/6p1/b2r1P1b/1P3R2/B1p1K1p1/B7/4Q3

Two white direct batteries and a black halfpin are visible in the position. Black sacrifices to play the wK and thus allow the wQ to guard the “e” file. The position taken by the wK determines which of the two pieces of the half-battery selfpins by capturing the front pieces of one of the batteries. Then the other battery fires and mates exploiting the double pin.

Each of the mating squares is guarded by two black pieces. If one of these sacrificed itself in B1 by a move in that square, the other would have no useful moves in B2 to abandon the guard, in turn. So one of these pieces moves instead twice to interfere the other. I like also that the four white pieces change their roles in cyclical form: this increases the artistic value of the problem, even if there are no model mates.


5th Prize - E401 Anatoly Skripnik (Russia)3R4/8/3n4/2N1k3/1B4p1/3q4/1Kpr1N2/3b4

I found only a few helpmates in two where the inversion of black moves and the inversion of white ones are combined in three solutions as shown in this problem. None of these, moreover, is closely enriched by Umnov effects as it happens in the three solutions of E401. Regarding the version E401a, there are no important changes in it, so I referred to the E401 for my evaluations.


1st Honorable Mention - E536 Viktor Yuzyuk (Ukraine)q1n3b1/P2P2Pn/8/1Pr1rP2/3k4/2ppp3/8/K7

Five solutions with promotion to Q and five moves in the same square are surely an remarkable result, but it detracts that the latter are divided between B1 and B2. Also the symmetry does not recommend me to assign a higher place to this problem.

1.Se2-c1 + Qe1-e2 2.Bc4-d5 Qe2*b5 # {,} 1.Sf2-d1 + Qe1-f2 2.Rf5-d5 Qf2-f7 #

Indirect white unpin with the check to specify the line where the wQ has to move; selfpin, direct unpin with interference. Altogether, an unusual presentation of the Grimshaw theme in two solutions with diagonal-orthogonal echo.

Very fine rex-solus with only six units, with analogies in the moves of the wQ and the two wS, playing both W1 and mates in the same squares. The Zilahi is part of this mechanism and it is due to the moves of the bK, which captures the piece in turn redundant. Such strategy makes the E477 a happy insight.

A good example of black and white dual avoidance. Black must choice carefully the units to block the squares c6 or e5, to avoid the wS selfpins in W1. Also the wS has two choices in its first move, but one fails in turn for anticipatory white selfpin.


6th Honorable Mention - E424 Zivko Janevski (Macedonia)8/b1B1pp2/2PR2p1/3bkpr1/2pp4/3r3p/2qp3K/8

 } 1.Bd5-f3 Kh2*h3 2.Ke5-f4 Rd6-e6 # {,} 1.Rd3-f3 Kh2-h1 2.Qc2-e4 Rd6*g6 #

Two pairs of connected solutions with battery play. After a selfblock the battery fires and one of the battery piece in turn moves to mate in the square left by the bK. On the other side, mutual black interferences to play the wK and battery mate.


Special Honorable Mention - E425 Fadil Abdurahmanovic (Bosnia and Herzegovina)8/8/n7/4p3/2pkp3/P3p1pp/bP4pb/R3K1N1

{set play:} 1...a3-a4 {!!(tempo)} 2.Kd4-d3 0-0-0 # {# (Rd1?),} 1.Sa6-b4 a3*b4 2.Bh2*g1 {!(tempo)} Ra1-d1 # {(0-0-0?!!)
    try play:} 1.Kd4-d3 0-0-0 # {# ??    0-0-0 is not legal!
}

The Retro elements with Castle-not Castle are nice, but the real point of interest is that white has a tempo move in set play and black instead in the actual play. As the author rightly comments, this is the very unusual anti-form of the Lindner theme. This problem is an improvement of another already published (see: yacpdb/391748 - editorial), so I had to decide whether to reward it or not, and if so, how to place it. By comparing E425 with its predecessor, we note a certain similarity, but also some important differences: first of all, in the Orbit helpmate there is no real black tempo in set play. Moreover, E425 is appreciable because all white force has a role in both phases: in particular the wPa3 moves both in set and in actual play. At the end, I opted for a special Honorable mention, that should be enough to highlight the problem. Although some constructive choices in the use of black material can be criticized, the author has motivated them following the discussion on the problem and I consider them secondary to the importance of the composition.

The bQ has two choices to reach its arrival square in two moves, but one fails for white pin. The play is slightly unbalanced, since in one solution the bQ could reach b5 in one move, but also in this case it would pin the wB. So the bQ must move before, through the critical square d7.
