trying to bet a 2X on a game and the book does not offer a spread only 1 X 2. home win is -112 draw is +228 and away win is +245. I would assume the 2X would be between -110 and -115.I am looking to bet both the draw and the away win here to cover the 2X. If I wanted to wager 1 unit total how would spread the unit so I make equal profit if my wager wins. I can calculate this manually but I would think theirs an online tool that would do this for me.
