Making an odds bet after a don't pass bet is called 'laying the odds' and is the opposite of a normal odds bet - you're betting that a 7 will be rolled before the point.The odds bet pays 2 to 1 on points of 4 and 10, 3 to 2 on a 5 and 9, and 6 to 5 on a 6 and 8. Making an odds bet after a pass bet is betting that the point will be thrown before a 7.
By taking the maximum odds bet every time you make a pass or don't pass bet, you maximize your winning potential and lower the house edge on your overall wager. Odds bets usually have a maximum bet amount that is some multiple of your pass or don't pass bet - 2X, 3X, 5X, etc. However, odds bets can only be made on top of other bets, so, if you make an odds bet, the house still has an edge (albeit a diminished one) on your overall wager. Odds bets are somewhat unique in that they are truly fair - the house has no edge at all on these bets.
