related parlay bet

On bet365.com, I tried to put a do a two-team parlay with the niners +13 and the under. But an error message comes up saying that "the bets are related and cannot be on the same betslip." I have never seen this before, but this is only the third site I have used. Anyone have any reasons for this?

sportingbet won't let me make bets like that as well w/ the same error message.

[Ken_AA]

the reason is because it cuts into their edge. VIPsportsbetting has always let me do it though.

Ken

thanks all for the info.

My book let me do it a few weeks ago with the Ravens/Steelers game.

I wish they hadn't. [img]/images/graemlins/frown.gif[/img]

It's actually called a correlated parlay. It's a type of bet that can be advantageous, so bookies generally don't allow it.

Eg say god offers me a bet on whether it'll rain tomorrow, and another bet on whether I'll get wet (by rain). He tells me that there's a 50% chance it'll rain tomorrow. I take a walk outside every day, so I know I'll get wet. So being the clever bastard that I am, I decide to parlay "won't rain" with "won't get wet", and "will rain" with "will get wet".

Each bet has a 50% chance, yet I get a payoff of 13:5!!! This is a pretty extreme example, but I think it gets the point across.
