A total of 78 sound (C+) and thematic entries by 49 composers from 17 countries participated in this formal tourney for helpmates in three or more moves (h#3-n) showing the Chernous Theme, as defined below. Of these, 20 problems were retained. The award standard was high, and the prizewinners were particularly enjoyable.

I wish to thank Vladimir Chernous for his thematic inspiration, Dan Meinking for his directorial efforts, and all the imaginative composers for their artistic contributions. It was a great honor to receive and judge so many wonderful creations. Our newly classified Chernous Theme has indeed made a successful debut!

Isaak Kavnatsky

Oak Park, December 2001

(1) A black line piece (BLP) checks the white King, either directly or as the rear piece of a battery;

(2) A white unit (WU) self-pins by interfering on the check-line, and is later unpinned by Black;

(3) The BLP moves again to self-block;

(4) The WU delivers mate.

The BLP may be promoted. The unpin of the WU may be by withdrawal or by line-closure.

Note: All

Claims of anticipation by July 1, 2002 to: Dan Meinking / 663 Steiner St. / Cincinnati, OH 45204 (USA) or by email: dmeinking@cinci.rr.com.

A classic Chernous Theme twist: twice the pre-pinned Knight is self-unpinned,
self-pinned (again), and unpinned. Perfect harmony and construction. Brilliant! Re2Sd3#1.Sf2 g4! (K~?) 2.Sh1 Se6 (Se2?) 3. Rxg4+ 4.Sf4Rg2Sh3# |
