wetware: No dice change here, Thad...as far as I know :-)

That's because you misunderstood Thad's post! He was supposing that in the existing game, with the existing dice, the receiver of the most doubles has the greater chance of winning. It's an intuitively appealing idea but he's asking whether there's any empirical data to confirm it. That's why he gave the post the title Doubles Theory rather than Dice Cheating.
