Magriel's
Backgammon published in 1976 is still considered the "bible of backgammon".
But our insight about the correct play has changed since good backgammon software is
available (
Jelly Fish ™ made the breakthrough in 1994).
So some of Magriel's recommendations did not survive the bots and are
not correct from today's view
1) . The following table contains
the major errors. It does not claim to be complete, but it should contain the most errors.
I recommend to mark those positions where Magriel probably erred with a pencil in the book before starting to read it. You can study it
much more relaxed then.
Where the best move in the column "Best Move" contains a link, you can have a look at the position and the
rollout results
2) by clicking on the link.
The table contains problems from section 2 of his book. Aditionally some of his recommendation about the opening moves
are not state of the art any more. For the best opening moves have a look at my article
Die Eröffnung (Teil 1) (currently only available in German).
1) Possibly new, stronger software will evaluate some decisions and moves differently in 5, 10 years. Definitively our knowledge about
the game will continue to develop and change over the years. So our insight what's right or wrong for Magriel's positions may change.
2) The results are based on rollouts with GNU Backgammon, version 0.14.3 (2005). 1296 rollouts, 0-ply,
non-truncated, cubeless.
