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