% - removed spaces inside macros that might show up in output 

% replaced
%   width  by  \@width
%   height by  \@height
%   depth  by  \@depth
%   "by 1" by  \@ne

% added:
%
% dimen \boardrule holding the width of the rule around the board

% put \global into \Whitetrue and \Whitefalse



\message{FMi updated chess version 96/07/21!!!}
%
% chess.sty
% ---------
% 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)
%


%
% Do we have language support? Otherwise take default language!
