NAME

6       bearoffdump - dump a position from the GNU Backgammon bearoff database

SYNOPSIS

9       bearoffdump file id

DESCRIPTION

12       bearoffdump takes the path to a GNU Backgammon bearoff database and a
13       position number and dumps the bearoff information for that position.
14       It can be called on either the one-sided bearoff database, normally
15       /usr/share/gnubg/gnubg_os0.bd; or the two-sided bearoff database, nor‐
16       mally /usr/share/gnubg/gnubg_ts0.bd.  The output from the former
17       includes the probabilities of bearing off all checkers in varying num‐
18       bers of moves.  The latter only gives the probability of winning and
19       doubling cube equity.
20
21       The id is difficult to derive if you don't know GNU Backgammon inter‐
22       nals.  Each possible combinatorial position of checkers and points is
23       assigned a position number, id divided by that number is the player
24       position, and id modulo that number is the opponent position.  The num‐
25       ber of points and checkers is set when building the bearoff database
26       and are shown by bearoffdump when run with any id.
