CHESS.DOC DOCUMENTATION FOR CHESS.COM
(SOURCE CODE WRITTEN IN FORTRAN)
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"
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!
