Мнение судьи:
An excellent example of development of the classical combinational direction – J. Fritz (Norodni Listy, 1933). The core of this endgame study consists in sacrificial combinations performed in a simple position; these are mirror-reflected in the homogeneity of play in the two thematic, skillfully intertwined variants. A minimal difference in the position of the white king (f3 vs. f4) brings about a unique interchange of sacrifices of white rook and bishop which form a geometrically strict “echo.” It should be noted that the passiveness of the black knight, which is unrelated to the main idea, is compensated for by the natural-looking diagram position, the light construction and the availability of tries with change ofplay–theadditionalstrengthsof this eye-catching find in the genre of endgame studies.

Мнение судьи:
A witty encounter of pieces (the irony of the plot dictates that White should twice refuse to capture the queen in the starting phase), which becomes hotter and more inspiring with each move, ends with a fork-blow by the knight at the very conclusion of the play (the difference in the black king’s final position on d2 vs. d3 playing the key role). In the solution, White performs a preliminary logical maneuver (4.sa2+!) in order to sacrifice his queen on the right square; and a couple of moves before the conclusion of play he needs to make an accurate move by his king 9.uf2!, making everything planned happen. This cohesive concept, with sacrificial play by pieces of both sides (in cases like this one, sacrifices are not irritating) is presented in a fresh and (from the endgame study viewpoint) harmonious way.

Мнение судьи:
A heated and intriguing encounter between the two sides, which are quite generous in spectacularly sacrificing the quartet of their major pieces. Remarkably, both White and Black consecutively refuse to capture the queens; and the play itself ends in advantageous exchange of the strongest pieces – a tool frequently used in over-the-board play. Still, the impression from the good and inventive play in the introductory part (White and Black are worth one another) is somewhat diminished by lack of luster in the finale itself.

Мнение судьи:
A large-scale endgame study with dynamic piece play. The pivot of the wide encounter is the key a1-h8 diagonal, on which consecutive play of the white battery (step by step, White exploits the black king’s lack of space) is combined with two variants of equal value leading to finales with echoed mates. In this entry, quite attractive is the active participation of actors directly involved in creating the conceptual plot; yet the play is somewhat schematic. As to the straightforward construction, however (technical pawns are often inevitable when implementing such concepts), it is seen as a positive point of the entry, which, by the way, is executed in Bohemian style; it is interesting to compare it with the endgame study of M. Havel, (2nd Prize, Norodni Listy, 1929), which also features battery play and two mates with the participation of three white pieces.

№ 5

Мнение судьи:
A logical endgame study with a foresight effect and a knight fork in the final act. The main idea consists in the king’s unexpected trick 5.Kh2! the sense of which is revealed only 6-8 moves later. The capture of the white motionless knight f4 in the solution is not necessary (Kg3, Be1, Bh3, Ng7 – Kg5, pp a3, b3, d6, f5, h5; 1…f4+ 2.Kh2!), but the author uses it in view of the additional variant 2…h4+ with another case of foresight displayed by the white king (also with repetition of the high point on the h2-square) and mating attack. If Black displayed more ingenuity in his play and queens were not e: changed in the introductory part, the entry would most likely be placed higher in the award.

№ 6

Мнение судьи:
This endgame study, with its piece play that is by no means apparent, presents a comple: of heterogeneous ideas: the Roman sacrifice 6.d8Q, the point 8.h6!, reciprocal refusals to make captures. Quite unexpected is the original ending itself, with the nonobvious sacrifice of the white bishop 12.Bd6+!, which nullifies Black’s efforts to win. It is noteworthy that the author tries to extend the intervals between the departures of some pieces from the board, making the actors live, move and choose the right squares leading to the conceptual finale in which Black, in spite of material advantage, has to settle for positional draw.

Мнение судьи:
A good development of the queen vs. pawn idea from the endgame study by M. Zinar (Georgian Internet Tourney, com., 2011). The highlights of the miniature included in this award include the well-thought-out actions of the white king in the two variants (3.Kd3! and 3.Kd4!) and the slow-looking move 6.Kd5!; they determine the inner life of this endgame study – simple in form but interesting in content. If in the diagram position the white king is shifted to f3 and the white pawn from а6 to а5, this results in an additional choice on the first move (1.a6! Kg7 2.Ke4 and then as in the solution; the wrong choice is 1.Ke4? a6! 2.Kd5 Kg7 3.Ke6 c5! 4.Kd5 Kh6 5.K:c5 f5 6.Kb6 f4-+) with play of the pawn couple on the a-file. The following endgame studies are awarded commendations ex aequo.

№ 8

Мнение судьи:
A restrained-looking but, on balance, appealing endgame study in which the white duo (R+B), by maneuvering skillfully, helps preserve and advance his h7-pawn to the promotion square. Very attractive are the two consecutive sacrifices of the bishop 9.Bh3! and 10.Bg4! Black’s first move, which is a pawn capture, however, does not make the preamble and the endgame study as a whole look any better. The final part of the play is reminiscent of the ending of the endgame study by M. Banaszek (Tidskrift for Schack, Prize, 1994).

№ 9

Мнение судьи:
This bishop ending seems to have been taken from an OTB game; in it, there is no limit to the white bishop’s sacrifice for the sake of creating a passed pawn on the kingside. The motifs are similar to those in the endgame study by E. Onate (H. Lommer JT, 1 h.m., 1970), but the logical choice 3.Kc1! in this entry adds freshness to it.

№ 10

Мнение судьи:
An endgame study that is useful for OTB players on account of the initial position and the spirit of the struggle, which is close to what is observed in an OTB game; it is decorated with castling, an underpromotion to rook (phoenix), and sacrifices of pieces. However, this endgame study is lacking in a real high point; and the concluding moves do not look impressive against the background of previous play. A different interpretation of the finale is also possible: 7...Nc3+ 8.Kc1! (8.Ka1?8...Kb4+ 9.Kb2 Ra2+ 10.Kc1 Ra1+ 11.Kb2 Rb1#) 8...Na2+ 9.Kd1 Nc3+ 10.Ke1! with return of the king to his initial square and win.
