In Response To: iGammon 2.0 (Tom Keith)

I updated last night when I saw it was available. Looks good. For a laugh, thought I'd see how high I could get the cube. Eventually got it to 2,147,483,648 (max). At least that what I thought until I tried a 2nd time:

And thus a calculation error with a backgammon: http://img121.imageshack.us/img121/7718/igammon2.jpg

Not sure why it's showing as negative. Perhaps test it yourself. Given the 2,147,483,648 limit, you could restrict the cube to a maximum of "just" 536,870,912, so that a gammon and backgammon can be calculated.

Any reason why Take Cube is on the left and Drop Cube is on the right? Given that the user is playing to the right, I was thinking maybe it would make more sense to put Take Cube on the right. Minor point anyway, just an observation.

- choice of direction of play (CW, CCW, random)

- Resign option, both for the player and the neural net

- tournament match play

- nackgammon and other BG variants

Thanks again!
