alanback: I described simulation in my earlier post. Backgammon (playBunny, 2010-07-18 14:28:23) If you are simulating the real dice action at the start of the game then each player occasionally will get the same dice, as they do in real life, and the roll will have to be done over. If you play GnuBg then you'll see that it does this, for example "A new session has been started --- GnuBg rolls 4, playBunny rolls 4 --- GnuBg rolls 2, playBunny rolls 4". It's not strictly necessary to go through those motions, as a binary coin toss will suffice, but that's how the GnuBg programmers did it and maybe Fencer liked the idea too.
