I am thinking about placing a bet on a couple of the NFL games today (on Bodog) and I was wondering a few things: If you win the bet no matter what, do you get your wager back PLUS the winnings? Like if I bet on the Patriots to win over the Saints monday night with a +3 point spread it says I am risking to win {content}.71…so if I win this bet do I walk away with .71 or {content}.71?? (**Note the bet is just an example)

This question relates to sports betting. This is what you do.. you take the underdog with the spread…then, with someone else, in the same, you take the favorite but don’t give a spread. Using this system you cannot lose, only win. For example..

Denver vs Portland…Denver is the underdog, and gets 7 points

You take on Denver with the 7 point spread.
With someone else, you take on Portland, but without giving a spread.

If Denver wins by any amount, you win that bet…
If Portland wins by more than 7, you win that bet…
In both these cases you are winning one and losing the other which cancels your bets.

BUT, IF PORTLAND WINS WITHIN 7 POINTS, YOU WIN BOTH BETS…GIVING YOU , WHILE THE WORST THAT CAN HAPPEN IS TYING.

Does anyone see any flaws in this system which will cause someone to lose money? Also, what do you guy think..
no bill it is with another person so there are no odds..therefore u cannot lose, only win.

The typical number in the line is the point spread and I understand that but what is the Over Under and how does it work?
