The 1st Prize was awarded to a problem of Rudenko and Shedey that was later selected for the FIDE Album.

David Brin (* 1950) "Brightness Reef," 1995.

Published in "Hlas ľudu" 3rd Commendation. This is a twin problem with b) Ra6->b6. Shown are black self-pins with changed mates after captures of wNc4 which threatens mate. In a) not 1. Rd3? Bxa5! but 1. Qa4 (2. Nd6# by double check) Qxc4, Nxc4 2. Bd5#, Re1#. In b) not 1. Qa4? Rb4! but 1. Rd3 (2. Nd2#) Qxc4, Nxc4 2. Rxg4#, Bg6#. Original comments from Hlas ľudu: "Zámena matov spojená s peknou väzbou čiernych figúr (M. Bednár, Kurima). Bohato motivované zámeny dvoch matov (L. Salai sr., Martin). Krásna, strategický bohato naplnená zámena dvoch matov (I. Kiss, Kežmarok)."
