New Bearoff Discs - Complete 15x15 bearoff on DVD
Hugh Sconyers
I have just released a new set of 12 DVD discs. These are an update to my
previous CD--Rom discs. These discs contain 4 databases for a total of over
50 gigs of data. The 4 database are:
Bearoff 15 x15 contains exact bearoff equities for ALL bearoff positions
in home board. It has equities for 4 cube positions: no cube - roller's
cube - center cube - opponent cube. This is 47 gigs of data covering about 3
billion positions and this information is not available in any other
program. Existing backgammon software very often misses the correct cubeful
answers and many times gets the wrong answer on a rollout.
Backgame 8 points provides probabilities of getting hit in backgame
positions. You can setup positions in the home board, 7 point and 8 point.
There is a feature for finding the best move.
Hyper Backgammon Equities provides the exact equities for all positions.
There is a feature for finding the best move. This is the same data that
MrHyperBot uses on GamesGrid.
1 Checker Race provides equities for a 1 checker race. This data covers
all races of 375 pips or less and provides 4 cube positions for each race.
These equities are helpful in deciding doubles and takes in backgammon.
In addition, there is VB code so that you can access the data for doing
research on bearoffs. I also hope this code will lead to existing software
to include a look-up feature to the data.
You can use the DVD without copying the data to your hard drive. If you
have the space on your hard drive(s), you can copy some or all the data to
your hard drive(s) for faster and easier access.
This set contains 12 DVD discs and Windows XP Interface. Your computer needs
a DVD drive.
The set of 12 DVD discs is $100 + shipping.

I'll start working on support in gnubg for the complete bearoff
database soon:
* show equities for a given bearoff position
* show the best move for a given bearoff position and dice
* use equitites for bearoff positions when analysing or playing money
sessions[*] and match play [**]
Barring any problems there'll be support within a month or so.

[*] Probably only useful for people who have copied the databases onto
disk; changings disks multiple times during analysis will probably be
a bit annoying :-)
[**] gnubg uses the cubeful bearoff equities from money play to
estimate the cubeful equities for match play.
