backgammon - the game of backgammon
backgammon [-] [-nrwb] [-s file]
This program lets you play backgammon against the computer
or against a
`friend'. All commands are only one letter, so you don't
need to type a
carriage return, except at the end of a move. The program
is mostly
self-explanatory: a question mark (?) will usually get some
help. If you
answer `y' when the program asks if you want the rules, you
will get text
explaining the rules of the game, some hints on strategy,
instructions on
how to use the program, and a tutorial consisting of a practice game
against the computer. A description of how to use the program can be obtained
by answering `y' when it asks if you want instructions.
The possible arguments for backgammon (most are unnecessary
but some are
very convenient) consist of:
-n don't ask for rules or instructions
-r player is red (implies n)
-w player is white (implies n)
-b two players, red and white (implies n)
-s file
recover previously saved game from file
An argument of -h gets a description of possible arguments.
When the program prompts by typing only your color, type a
space or carriage
return to roll, or
d to double
r to redraw the board
q to quit
s to save the game for later
When the program prompts with 'Move:', type
r to redraw the board
q to quit
s to save the game
or a move, which is a sequence of
s-f move from s to f
s/r move one man on s the roll r separated by commas or
spaces and
ending with a newline. Available abbreviations are
s-f1-f2 means s-f1,f1-f2
s/r1r2 means s/r1,s/r2
Use b for bar and h for home, or 0 or 25 as appropriate.

The strategy is the ``pubeval'' algorithm of Gerry Tesauro,
with minimal
doubling logic added.
