I think I've figured out a way to use Bodog's 10% bonus (clearable at 1x if you don't use Neteller) to create a true hedge bet against the Mansion free bet. This strategy actually slightly INCREASES EV over letting the free bet ride. I made my Mansion free bet on Pittsburgh -4.5 before it got taken down for the weekend. As I stand to increase my BR by 1/3 by taking the sure thing, I'm going to hedge tha muthafucka and guarantee myself $500. Here's the plan:

1) Wait until Bodog posts a line for the Steelers/Dolphins game, probably Monday. Assuming it's Miami +4, like every other sportsbook right now...

2) Deposit $500 at Bodog using Firepay, receiving a $50 bonus which is immediately playable in their sportsbook and cashable at 1x. (I would use Neteller but then the bonus is cashable at 3x.)

3) Wager all $550 on Miami, buying a half-point to make the line +4.5, making it a true hedge (no chance of pushing). Buying the half-point decreases the odds to 1:1.2 (-120 for you sportsbettors), meaning I'll be wagering $550 to win $458.33

4) Root for Miami so I can win an extra $8.33 (see below)

5) If Pittsburgh wins by 5 or more, collect $2100 from Mansion ($1000 winnings and $1100 original bet), for a net gain of $500 ($1000 minus $500 deposited on Bodog).

6) If Miami wins, or Pittsburgh wins by 4 or less, collect $1100 from Mansion (thanks to the refund), and $1008.33 from Bodog ($550 original bet plus $458.33 winnings) for a net gain of $508.33. The Bodog $ is immediately cashable because I've wagered it 1x, but I'll probably play some NLHE for cover before I withdraw.

Major caveat: Bodog only lets you buy up to one point and doesn't let you buy points if the line is off-standard (different odds for each side). So I won't know for sure that this will work until their line comes out. I'll post a follow-up when it does.

Please let me know if you see any flaws in my reasoning.
