Просто нет слов от восхищения...

Мнение судьи.
This is the best study of the tourney. There are three main lines ending in a midboard mirror stalemate, with a wS either pinned diagonally, vertically or horizontally! Only a recent study by Krug (HHdbV#o2o28) comes near with three knights being simultaneously pinned in a mirror stalemate position with the wK cornered, and a study by Sarychev (EG#o3369) with three stalemates in different lines, but also with wK cornered and one of the stalemates is not a mirror stalemate. The main lines in the present study are much better. After the introduction (I do not like the «try» very much), Black counters with a bishop sacriﬁce: 3...Bd7+! which White must accept. As a result the wS is pinned after the queen promotion and cannot capture on c6. But White returns the honours with an echo sacriﬁce 5.Bd2!! getting rid of the bishop. Black, having two queens, has three relevant checks and each one is countered by a selfpinning discovered check of the wS ending in stalemate.

Мнение судьи.
This is a truly marvellous study which becomes better and better when you begin to understand what is going on. The point is that the main line and both tries end with a Q vs. Pending, with the bK diagonally approaching d5 or f5 in the tries, but e5 in the solution, which is a well-known theoretical draw. Ok, nice, but then we see that the key move is already a surprise, forcing the bK to the right square (a2). Then there is a tactical intermezzo until move 6...Be4. What follows next is a queen sacriﬁce coming out of the blue: 7.Qa1+!! The amusing thing is that it is not really a queen sacriﬁce as the wQ would also be lost when White falls into the thematic try 7.BXe4? because after another tactical intermezzo Black captures the wQ when he plays his rook to h8 (9...RXh8). In the solution, Black also has to play 1o...Rh8 which is not a capture as the wQ was sacriﬁced, a brilliant and perhaps new idea! The only difference is that in the solution the bK is at a1, and in the 2nd thematic try at b1!
There are some move transposition black duals (Qf8) in both thematic tries, and perhaps a more serious black dual (16. . .Kc5 17.e7 QXe7 18.Kg7 Kd6), which is not a true time wasting dual (19.Kg8 Qg5+ 20.Kh7 Ke7) in the 1st thematic try, but I accept it as a minor dual.

Мнение судьи.
First, there is a curious positional draw after 1.Rh8? after which White cannot make progress. The play becomes interesting after 3...Qh2. The logical try shows that Black has a nasty pin when White carries out his plan. He uses a precise preparatory manoeuvre (Be7-Rf4-Ra4-Bf6) to move the wRc4 to a4, and now the plan wins. Despite “database” material, the moves are easy to comprehend.

Мнение судьи.
This is a tactical study whose introduction features a bR sacriﬁce for promotion, a wB sacriﬁce to prevent the promotion and another wB sacriﬁce to block the bP. Then the highlight of the study follows: a great bB sacriﬁce (7...Bd7+!!) followed by a capture refusal (8.Kd8!!). The composer calls this optically nice position the «EG jubilee tree» which is a nice gesture, but we fail to see a direct connection. The study ends with 4 main lines each with wS sacriﬁces and forks.

Мнение судьи.
Apart from a terribly unsound study by Pomogalov (#08083) this is the ﬁrst study in which three bishop promotions are needed for a draw. However, the play is very limited so, therefore, a special prize is awarded for the new task record.

Мнение судьи.
I like the two piece sacriﬁces on g7 and the three knight promotions for a draw. Initially I curiously overlooked the connection between the two main lines after the S promotions, but the (obvious!) point is that either the bB or the bR captures the wSc2 that stops the bPe2 from promoting.

P.S. MG - Mario Guido Garcia (Argentina).

Мнение судьи.
This has an introduction with quite a few captures but also with two sacriﬁces from each side. It is a solid reciprocal zugzwang study with an original zz position and a good try, ﬁnishing with a model mate.

Мнение судьи.
This is a ﬁne study with (full point) reciprocal zugzwang. Ihe excellent sacriﬁce (3.c6!!)gets on the right side of the zz whereas the more natural move 3.Sxe3? is the logical try. The point is that after 11.h4 the move that refutes the white plan in the thematic try (10...Be3) does not work (11...Be3 12.e6) because the a3-f8 diagonal is blocked.

Мнение судьи.
The point of the study is the original wK manoeuvre Kg7-Kf7-Ke7-Kf6 before winning the S and P vs S ending. There is a good thematic try 3.Sa6? when a similar ending draws. Both solution and try have a knight promotion.

This is a zz study with a natural thematic try. The pattern of the pieces in the top left corner of the board is original.

Мнение судьи.
The introduction is a bit too violent to my taste, e.g. with the bQ being captured without having moved. The rest is interesting with S and R promotions in a draw study with good counter play (12...Bb3!) and a rabid rook ending with accurate wR moves. The stalemate is well-known (Maksimovskikh & Shupletsov, #28739) and the study is partly anticipated by a recent one by Minski (#01012), which has the counter move 1n a w1n study.

Мнение судьи.
Zinar composed a lot of studies with such schemes (e.g. #00637, 01806) and it was no surprise to me that he turned out to be the composer of this study. His studies usually have accurate king moves, or extra underpromotions. In this case we have a reciprocal zugzwang study with an excellent try (1. gxh5? 4...a6!) and a great key move (1.b6!) to get on the right side of the zz position.

This has a nice point (8.Qxg7+ Qxg7 9.hxg7+ with check) with a thematic try. The optically appealing position in the top left corner seems to be original.

Мнение судьи.
4.Ba8! and 7.Ba2! are very good moves. The ﬁnal point is that the bQ cannot access b1. This is easy to understand despite being database material.

7.Rh6! is an excellent move, also returning to its original square (Rundlauf), avoiding a block of the e7-square.

Мнение судьи.
This study ends in a positional draw featuring a zz position in which White has only OS vs. QQ with BTM. There are some good moves; e.g. 2.Qc6 (unexplained by the composers) which covers e4 and b5 and anticipates a check at h1.

Мнение судьи.
The ﬁnal position, the highlight of the study with 3 active selfblocks of the bB, is unfortunately anticipated by Liburkin (#66408), although that study has a different ﬁnish. This study is an improvement as it has a thematic try in which Black on his turn can go wrong with an echo ﬁnal position.

Чтобы было понятно: этюд Венинка.

Мнение судьи.
This is the ﬁrst sound study that uses Weenink’s (#76420) famous move 1.Bb1!! As it occurs in a try, almost inevitably, the try is better than the main line. The pawn ending with the oppositions and the move 12.b3! is known from Irirarte (#31031). The composer gives two exclamation marks for 5.Kg7, but it is the only move that makes sense. Anyway, a nice re-working of old ideas.
