Мнение судьи:
Very sympathetic work! All versions are humanly solvable and fun. Of these, it leads to more practical endgame. Good! The game is beautifully built up to the culmination of the work. It then appears white can't stop the mate threat, or don't know avoids the material disadvantage. After a surprising bishop and queen sacrifice the stalemate is unavoidable.

Мнение судьи:
The structure of study is complex, with excellent strategic content. There are two white and one black queen promotions here. Black has a hidden winning position, but this is not visible easily. White avoids this in main line with an impressive queen sacrifice on g1. The other queen sacrifice on g2 leads to the thematic try.

Мнение судьи:
Why sp. prize? It may well be that this work does not accumulate more shining tactical motifs. Otherwise the exact maneuver of the white rook is very valuable. Black doesn`t' capture the rook, so avoids the stalemate, but the play leads to a positional draw. The try seems to be good, but finally black wins by a surprising Knight fork. Fine work.

Мнение судьи:
After 5.Kb2 the play is nice. Black has more mate threats, white avoids these with sacrifices. The pendulum moving of queens are beautiful. The hard introduction play leads to a difficult variations. I think, it’s not easy to evaluate the 4th .... Qg2 version by one man.

Мнение судьи:
It's a very cute little work. The key motif is simple: the wrong corner lead to draw, but white must capture both 'f' pawns. In the main version this succeeds, but in the thematic try doesn`t. The blacks counterplay is based on impressive sacrifices: 1...Bg3+, 2...Re3+. Nice.

Мнение судьи:
Two knights vs. rook and bishop in two main lines. Not easy to find the best play of white, especially after 3...Rc7. White creates threats through silent knight moves, and reaches the draw by forks. Remarkable composition.

Мнение судьи:
It's a small but lovely study. The game begins with a really good key move. White avoids a try in the second move also, but he can not stop the black pawn promotion. The culmination of the study is the nice knight sacrifice 6.Nf1+, after which the perpetual chess is the end of the game.

Мнение судьи:
A very difficult study in two phases. White reaches the stalemate in one variant, while in the other the positional draw.

Мнение судьи:
An multiphase study derived from a previous configuration by the composer of Poland White achieves a different color bishop endgame, and it's draw. A little bit difficult play.

Мнение судьи:
An appropriate recreation of a study by the same author, published in 1990.White save the game with a cute combination. The rook promotion of black don't help, the end of game is ideal stalemate.
