Would you be so kind as to explain Kelly in layman's terms?
Kelly is a math formula used to determine the optimum bet size. It will, in theory, find the best risk/reward ratio.
Since the house has an edge it will always win more than it loses, but in short term there will be variance. In order to protect the bankroll from this variance only a percentage of the bankroll should be allowed to be risked on each roll. How much to risk on each roll is calculated by the Kelly formula.
For a dice game the formula is really simple:
Where p = probability of winning and q = probability of losing.
When someone places a <49.5% bet the house takes the opposite bet >49.5%. The houses probability of winning is 50.5% on this bet.
The Kelly value is 1% which is equal to the house edge. In theory a max bet of 1% should be the best risk/reward ratio but in practice, as Just-Dice demonstrated, it is still really risky and should be set to less than 1%.
