% ---------
% Style file for writing about chess games
% Author : Piet Tutelaers (internet: rcpt@urc.tue.nl)
% Version: 1.2 (Febr. 1992)
% Improvements over version 1.1
% - added `\v{S}ahovski Informator' symbols
% -`en passant capture' bug fixed (reported by Jonathan Mestel)
% -change {--} into \hbox{--} to prevent hyphenation within move
% -\move's lined up on last row (or digit in case of castling)
% -handling of promotion improved
% * Black promotion problem solved (plain TeX)
% * comment allowed also with promotion
% * if no promotion piece is provided a default Q(ueen) is supposed
% Thanks to: Jan Jaap Spreij (puls@cs.rug.nl)
% -improved interface to plain TeX
% -language support using the babel package from Johannes Braams
% (currently support for english, dutch, german and french but you
% can add an extra language `foreign' by:
% 1. creating `foreign.sty' for cooperating with `babel'
% 2. search for FOREIGN and follow the instructions in the comments)
% - \begin{nochess} ... \end{nochess}
% -chessfig10 renamed to chessf10 (service to MSDOS users)
% Version: 1.1 (17 Nov 1990)
% Improvements over version 1.0:
% -TeX code cleaned up (thanks to TeX-wizzard Victor Eijkhout)
% -moving a King does not generate a castling move when this
% King already moved
% -renamed internal macro `\\' because LaTeX uses that
% -better hooks for foreign languages (look for lines marked with
% %%FOREIGN%%)
% Torture test:
% If you change something in the chess.sty style check if everything
% else is still working with torture-test.ltx (LaTeX) or
% torture-test.tex (plain TeX).
% Known problems:
% -The analysis mode can not be used within arguments of macros
% not: \centerline{|21.N5*f3|} but: |\centerline{21.N5*f3}|
% Version: 1.0 (5 Jan 1990)
