No, if you bet just for the Cats to win, you would get the $3.12 odds. If you bet them to win by 1-39 you would get the $3.75 odds, but you wouldn't get anything if you bet for them to win by 1-39 and they won by 40.So the $3.12 only kicks in if we were to win by 40 points plus?
Edit: So you have to place either a straight win bet or a win margin bet.
