I have a one-time Bonus Play that can be used on either blackjack or craps at a casino in Vegas. I don't know anything about craps, so I'm wondering if there's a bet I can place with the Bonus Play and also bet half that amount in real money so that I win half of the Bonus Play amount. I know it won't be without risk, so what would that bet be (pass/don't pass, come/don't come) and what are the odds I lose both?
