Thanks for the quick responses!

Joseph, if you're reading this, could you contact me about your set of 
test positions as soon as possible?

I was also thinking I could also add positions in books by Famous People 
(Magriel, etc) to any existing test set (would also be interesting to see 
how a deep-search gnubg differs from human analysis, or other computer 
backgammon analysis).

I am making good progress on my backgammon program and hope to have a 
tournament set up soon, between existing forward-pruned 3-ply (you call 
2-ply?) search in gnubg versus star1/star2 3-ply search (no forward 
pruning). I've been able to write my own code for everything except the 
evaluation function (i.e. NN).

Some people, when confronted with a problem, think "I know, I'll use 
regular expressions."  Now they have two problems.
