In_Chess is a collection of Endgame Chess Problems (includes a template file for future(*) additions).
 
The Chess Problems included in these 3 files come from two sources. In each file, 25 problems exist as variants; the first 20 are from 'The Chess Problem', the final 5 are from 'Canadian Chess Problems'. Further information is presented in a separate *txt file, 'Sources.txt'.
 
Two distinct schemes are provided: the standard Zillions set and the Black & White layout commonly used in publications.
 
 
(*) A template is provided for personal use. If anyone would like to also submit their own volume of chess problems, separate *.zrf file(s) can be inserted into the In_Chess collection. To be included, please document your chess problems and their sources as already shown with the original volume one (_v1) files. Unusual challenges featuring special chess pieces, rules, or board layouts will require extra care. Please send any completed *.zrf files, etc. directly to my personal e-mail address.
My intention is to reasonably co-ordinate the public updates of the In_Chess submission (ie; quarterly or semi-annually). Due to active copyright issues, etc., some of the .zrf files might be turned down - the final acceptance will rest with the Zillions team.
