№ 1

Мнение судьи:
This is a very entertaining study. White must sacrifice both his rooks at h8. After one has recovered from the surprise, White finishes off by the excellent quiet move 12.Qd6! The inactive Bb6 is a blemish, and also the initial position of the ws being attacked by the b p c2 is a pity.

Мнение судьи:
We see a perfect symmetry study, i.e. symmetry of the initial position, but also with a unique solution and a unique refutation of the thematic try. Such studies might suffer from a mechanical solution, but here we see fine moves like 1...Nd4!, 5.Kd7!, and 9.Ke7!

Мнение судьи:
This shows us a good construction of a (non)-obvious stalemate, which surprisingly seems to be original. The zugzwang position is remarkable. It is a pity that the less obvious move (2.Kh8?) is the thematic try. The bKa6 does not play.

Мнение судьи:
The final double-check ideal midboard mate is nice mate. This study has some excellent moves: the key (1.Nd1!), the nice knight manoeuvre 4.Nd6+ 5.Nc4+, and the surprise 7.Rd3!. Unfortunately, we see another piece (wRg2) that is passive except for the fact that it delivers half of the mate! The initial version was (probably) unsound, but the author managed to provide a quick correction.

Мнение судьи:
The stalemate combination with the queen sacrifice is original (the exact stalemate is not). wNh2 is captured without playing. The study makes a pleasant impression with rook sacrifices in the introduction by both sides.

№ 6

Мнение судьи:
This is an adventurous study with a whole series of surprising moves: 1...Ne5+, 2...Rf6+, a refusal to capture a whole queen (4...Qh3+), a queen sacrifice (5.Qh4), and a rook sacrifice (6.Rd8+), stalemate avoidance and a mate. Again, a passive piece (wmh8) is captured.

Мнение судьи:
This is a curious study. The wK has to shelter three times behind a wB for the checks delivered by the bR. bBb1 remains passive in the main line.

№ 8

Мнение судьи:
A study that one begins to appreciate better and better when trying to understand what is going on. Black sacrifices a bishop to set up a defence which is based on stalemate. On an open board both queens are attacked by a rook (7.Rb6!, 7...Rd5+!) and unable to move. White must sacrifice his queen (8.Ke3!) and Black counters by sacrificing his last rook. Then stalemate seems inevitable, but after a stunning queen sacrifice, White can play a crosscheck and mates.

№ 9

Мнение судьи:
A mate with two active self-blocks. Despite the fact that White plays various quiet and remarkable moves (2.Rh2, 6.Bc6, 7.Kb8), Black is helpless. The whole idea looks familiar, but only the mate position is known (Stavrietsky HHdbV#21467).

№ 10

Мнение судьи:
The last couple of moves of this study are remarkable, and during play there are some surprises (1...Rf2+! 5...Nh2+!) this study has too many checks.

№ 11

Мнение судьи:
Of course studies like this one are puzzles rather than artistic studies. However, I do like the idea that the Zwickmьhle combination is used to replace a strong defence (6...Be8) by a weaker defence (16...Ra7).
