www.arves.org - Selected Chess Compositions

On December 2nd Jan Rusinek turned 75.

Rusinek, Jan 1950

Happily, this year Jan published Selected Chess
Compositions in Polish, which is also available as a PDF file:
https://drive.google.com/drive/folders/1S_MOvZ6fjYX6W45UGQozzFqn9W5M6HU8
According to Jan, his favorite theme is stalemate in all its variations: final position,
underpromotions, and stalemate avoidance. Of course, mate, zugzwang, positional draw, and
problem themes also feature in his work.
