I don't understand. I thought it must be very simple to count probability using brute force analysis, so why to use neural networks or statistical analysis for backgammon?
I am wondering what was the longest anti backgammon game here so far, without prolonging for purpose. I found so far: http://brainking.com/en/ArchivedGame?g=353288
It was resigned so it would last few moves more. I know Fencer can find the longest game with one simple database operation
