After the preliminary award a cook was found in the 1st prize study. A correction was made and the corrected version is shown here. In addition, a cook was found in the study (D37) that was initially awarded 2nd honourable mention. No correction was possible and the study was removed from the award. Finally, the 4th prize winner offered a new version of his study.

6...Rc8!!+ What a move. A misprint? Not at all.
Before this move, all the main actors are brought into play. The composer has shown great technical skill in luring White’s rook into its cave/grave on f3. The sidelines in this part of the study (especially 1...Re4, 2. Rh6 and 6...Nd6+) are unfortunately extremely difficult and require help from tablebases.
But then comes... 6...Rc8!!+ and all is forgiven. Did I mention this move already? Now White has only a narrow king route to avoid a perpetual or loss of his rook. In the end the trip seems to no avail as the rook is forked leaving the drawing material of KBN vs KN. But Black’s knight is dramatically trapped midboard and it is conquered just one move before the black king comes to the rescue. A memorable study in classical style.

Мнение судьи.
Generally speaking, I am not a fan of studies with several main lines (not to speak of sub main lines), as it conflicts with the principle of clarity which is dear to me. But here the thematic coherence between the three lines reaches a very high level. We witness three rook promotions on square d8 to avoid three different stalemates. In addition there are two other stalemates after queen promotions. In the five stalemates Black’s king is caught on five different squares, f5, f8, g5, g8 and h7. The economy is excellent, especially considering the task nature of the study. It may not be obvious to everyone that RRB vs Q is a general win, but this weakness is an inherent part of the scheme and the final moves of the study offer good clarity. This study in my view shows the highest level of constructional skill in the tournament.

Мнение судьи.
A study with a well hidden theme. The initial position is rather unnatural (the pawn confrontation c5-e5 vs. d6 being mymain complaint), but this is adequately compensated by the tour de force that follows. In fact this study more than anything highlights the art of creating an introduction. Obviously the composer must have worked his way back from the final unavoidable stalemate. But the introduction has so many fine intricacies (the line openings 3...e3 and 7. d5 just to mention a couple) that one forgets that it is an introduction. In other words, the two parts of the study - introduction and climax - melt together into a harmonic whole.
The final stalemate is known from a (cooked) study by Emil Richter (#66127), preventing this study from fighting for first prize.

Мнение судьи.
Already from the configuration of the pieces in the top left corner of the diagram one suspects that a knight promotion is coming up. But that this knight has to take a detour via b2 before returning to b8 comes as a complete surprise and makes this study memorable.
There are a number of additional subtleties, for instance the arrival of the black queen on g1 to cover c5 avoiding the dual mating move 15. Nc5#. Also, the way the composer has managed to avoid the move transposition 5. b8N+? deserves praise.
The mating picture is known from a study by Aliev (#6777).

Not all epic studies are bad. This one has two phases of equal value. A tactical festival of forks and sacs followed by an interesting knight endgame.

A tribute to the founders of the endgame study. The winning manouvre starting with 13. Kc6 was shown by Kling and Horwitz in 1851! (#83878). On his eighth move White can chose among three moves. In two cases the Black rook ends up on d3 and d2 respectively securing him a draw. In the third it ends up on d4, which proves a decisive weakness in the black position.

Мнение судьи.
White’s main plan 1.Qb6? Qd2+ 2.Kg6 fails to 2...Kd7 3. Bc6+ Ke6 4. Bd5+ Kxd5 when Black’s pawns secure him a draw. Therefore White must first get rid of the pawn on a4. This requires a foreplan of 22 accurate moves.

Мнение судьи.
This study may have been inspired by the composer’s own Special Prize from the FIDE Olympic Tournament in Composing 2016 showing a stalemate with five pinned pieces. The five pieces are here pinned in a different pattern offering a clear improvement. The composer has managed to spare a pawn and a piece and has avoided the “Black to move” stipulation. The play also flows more naturally beginning with 4 quiet half moves (in this kind of position I consider the capture of a pawn to be a quiet move).
I only have praise for the composer. But still, this is a task style problem and considering the task had already been accomplished, a commendation is the maximum honour I am able to give.

A clear and excellent idea. Rundlauf of the White queen. Unfortunately this happens at the cost of a capture on a7. Also at the peak of the study (7. b4!!) I need help from the tablebases to understand why other moves like 7.se1+ or 7. ue7 are insufficient to draw.

Мнение судьи.
The idea of this study is clear. A tempo move is necessary for White to make rogress. The actual variations are less clear. It takes a lot of work to convince oneself that the ntended solution is indeed the only way to win. This is in part due to some loss of ime duals and transpositions to the mainline.

Poor judge. He was really put to the task by this amusing task study. How to place this? The idea here is not simply showing the fivefold knight promotion (which has been show on other occasions, even in pawn studies), but rather the systematic and humorous movement of the Black king and the entire forest of white pawns. In fact the economy of the study is excellent, leaving only the necessary White army to force the win in the end.
