Its not imaginary and I am betting it. If you follow that sequence and bet the calculated amounts on the ML and RL you essentially have a -1 line. A -1 line means in order to win, the team would have win by more than 2, and if the victory was by 1 it'd be a push. And that is exactly what these 2 bets in conjunction allow to happen. I know the -1 was offered at Pinny but for most of us USA customers that is no longer a viable option.is just an imaginary line? You made it up but aren`t actualy betting it.
