% 1. Title: Chess End-Game -- King+Rook versus King+Pawn on a7
%    (usually abbreviated KRKPA7).  The pawn on a7 means it is one square
%    away from queening.  It is the King+Rook's side (white) to move.

% 4. Relevant Information:
%       The dataset format is described below.  Note: the format of this
%     database was modified on 2/26/90 to conform with the format of all
%     the other databases in the UCI repository of machine learning databases.
% 
% 5. Number of Instances: 3196 total
% 
% 6. Number of Attributes: 36
% 
% 7. Attribute Summaries:
%     Classes (2):  -- White-can-win ("won") and White-cannot-win ("nowin").
%           I believe that White is deemed to be unable to win if the Black pawn
%           can safely advance.
%     Attributes: see Shapiro's book.
% 
% 8. Missing Attributes: --  none
% 
% 9. Class Distribution:
%     In 1669 of the positions (52%), White can win.
%     In 1527 of the positions (48%), White cannot win.
% 
% The format for instances in this database is a sequence of 37 attribute values.
% Each instance is a board-descriptions for this chess endgame.  The first
% 36 attributes describe the board.  The last (37th) attribute is the
% classification: "win" or "nowin".  There are 0 missing values.
% A typical board-description is
% 
% f,f,f,f,f,f,f,f,f,f,f,f,l,f,n,f,f,t,f,f,f,f,f,f,f,t,f,f,f,f,f,f,f,t,t,n,won
% 
% The names of the features do not appear in the board-descriptions.
% Instead, each feature correponds to a particular position in the
% feature-value list.  For example, the head of this list is the value
% for the feature "bkblk".  The following is the list of features, in
% the order in which their values appear in the feature-value list:
% 
% [bkblk,bknwy,bkon8,bkona,bkspr,bkxbq,bkxcr,bkxwp,blxwp,bxqsq,cntxt,dsopp,dwipd,
%  hdchk,katri,mulch,qxmsq,r2ar8,reskd,reskr,rimmx,rkxwp,rxmsq,simpl,skach,skewr,
%  skrxp,spcop,stlmt,thrsk,wkcti,wkna8,wknck,wkovl,wkpos,wtoeg]
% 
% In the file, there is one instance (board position) per line.
