Well only one person can win the weekly free bet so it doesn't matter too much there. I guess you've got an advantage if you use two accounts with different scores as you've doubled your chance of winning but you've still got to do great on one of them to win. As someone else mentioned, it's probably going to be a disadvantage having more than one account, especially if you're not consistent on one of them.
It'd definitely be a disadvantage to me! As it is, there are weeks I won't change my picks because of time, and those 10 "free picks" I definitely use up over the season, so yeah, I agree. If you want to have more than 1 account, power to you, and more for me to win in the end ha ha;) I think in fact, one might have the disadvantage of overconfidence if having more than 1 pick. Makes you a bit less careful I would say.
@Trofo: Now THAT is a disadvantage I overlooked... I can certainly imagine a scenario where you could be tied with an account on points with 1 more game to go, and pick the same one as the one you've tied in on one account, and pick aother result with your other account! So I might humbly suggest here my earlier recommendation: allow multi accounts but declare the main account for free bet winnings only for that one!
@pamoldar: I'd do the sidebet but I'm also Liverpool and toke has lost his appetite for it heh.
