NAME

       bearoffdump - dump a position from the GNU Backgammon bearoff database

SYNOPSIS

       bearoffdump file id

DESCRIPTION

       bearoffdump  takes  the  path  to  a  GNU Backgammon bearoff database and a position number and dumps the
       bearoff information for that position.  It can be  called  on  either  the  one-sided  bearoff  database,
       normally     /usr/share/gnubg/gnubg_os0.bd;    or    the    two-sided    bearoff    database,    normally
       /usr/share/gnubg/gnubg_ts0.bd.  The output from the former includes the probabilities of bearing off  all
       checkers in varying numbers of moves.  The latter only gives the probability of winning and doubling cube
       equity.

       The  id  is  difficult to derive if you don't know GNU Backgammon internals.  Each possible combinatorial
       position of checkers and points is assigned a position number, id divided by that number  is  the  player
       position,  and  id modulo that number is the opponent position.  The number of points and checkers is set
       when building the bearoff database and are shown by bearoffdump when run with any id.
