CHESS.DOC DOCUMENTATION FOR CHESS.COM (SOURCE CODE WRITTEN IN FORTRAN) *** CAUTION: REQUIRES AT LEAST 40K CP/M TO RUN *** DECEMBER 25, 1979 CHESS.COM USES ALGEBRAIC NOTATION AND A BOARD DISPLAY SIMILAR TO MICROCHESS: A B C D E F G H 8 BR BN BB BQ BK BB BN BR 8 7 BP BP BP BP BP BP BP BP 7 6 -- :: -- :: -- :: -- :: 6 5 :: -- :: -- :: -- :: -- 5 4 -- :: -- :: -- :: -- :: 4 3 :: -- :: -- :: -- :: -- 3 2 WP WP WP WP WP WP WP WP 2 1 WR WN WB WQ WK WB WN WR 1 A B C D E F G H THERE ARE TWO OTHER COMMANDS WHICH DISPLAY THE BOARD AND ASK THE COMPUTER IF IT WILL ACCEPT A DRAW. THEY ARE "BOARD" AND "DRAW", RESPECTIVELY. TO CASTLE KING-SIDE, TYPE IN O-O TO CASTLE QUEEN-SIDE TYPE IN O-OO IF YOU TRY O-O-O IT SAYS "ILLEGAL ATTEMPT TO CASTLE" TYPICAL OPENING MOVE, 'E2-E4' CR. ALWAYS USE CAPITAL LETTERS, FORTRAN-CHESS DOES NOT ACCEPT LOWER CASE. I HAVE RUN SEVERAL GAMES COMPARING THE FORTRAN-CHESS (FC) PROGRAM AGAINST FIDELITY ELECTRONICS' CHESS CHALLENGER 7 (CC7) (C) 1978 FIDELITY ELECTRONICS. WITH FC AT LEVEL 0 (IT ONLY HAS 0 AND 1) AND CC7 AT LEVEL 1 (CC7 HAS 6 LEVELS OF PLAY) FC WINS. WITH FC AT LEVEL 0 AND CC7 AT LEVEL 2 CC7 WINS. FC'S RESPONSE TIME AT LEVEL 0 VARIES BUT IS NEVER MORE THAN 90 SECONDS. I HAVE NOT YET CLOCKED IT AT LEVEL 1, BUT IT HAS A SIGNIFICANTLY LONGER RESPONSE TIME (AT LEAST AS MUCH AS SEVERAL MINUTES -- ESTIMATION). HAVE FUN! JIM MILLS C.A.C.H.E. MEMBER
