While its true that it is essentially a positonal game, since even at 1-ply
(meaning no look-ahead) the strongest program is on average as strong or
stronger than the best players in the world, it is also a far simpler game to do
this. With 2 moves of look ahead, it clearly becomes stronger (on average) than
the best human players.
It was done with neural nets, and is extremely well documented on the internet,
however the depth of backgammon cannot possibly be compared with that of Go.
Think of how many move are required to complete a game, not to mention the
number of possible moves that can be played at any given moment.
