Suppose you're making a sports bet on an American Football game. You bet $10 that the Griffons will beat the Hydras by 3 points or more. It doesn't really matter to you if George or Bob are the ones to take your action, since they're both trustworthy friends of yours and they can't affect the outcome. But if you're betting against Hank, who manages the Griffons, that's something you want to be made aware of. Even if he can't directly influence the game, knowing that your opponent picked the players for the team he's betting against, he's got a lot of information that you can't easily come by, and it'd be a bad move to bet against him. It's a bit of a bait and switch to say that you're betting against another neutral party when you're in fact betting against someone involved in the game.
