Hi!

Thanks for your observations. We're aware of the bad evaluations of 
outside primes, but these kind of positions are extreamly hard to train. 
I don't think JellyFish does thes kinds of positions any better, and 
maybe not even Snowie. This is still a weak point of most bots. Thanks 
anyway.

Excellent manual? Where? Which manual are you talking about? ;-)

Pasting in a fake start could be a simple solution with some scripting, 
however I really believe JellyFish .gam format do support positions in 
the game line, but I'm not sure if Snowie can import .gam files with 
positions in it. (At least I don't think GNU backgammon can handle 
positions in .gam files.)

Maybe someone can work out the format based on the last game of this match:

It would be excellent if someone can work this out. I'm not sure if 
anyone have tried this seriously, but I think it will be a hard and a 
time consuming task.

Hei og hopp!
