No.
So if you added Barber to all your straight picks, so you turn them all into doubles. Let's say Conor, Nastrat, CDF, Osbourne and Ladet make them all doubles with Barber, so you get some extra juice out of it.
Conor + Barber
CDF + Barber
Nasrat + Barber
Ladet + Barber
Osbourne + Barber
Then you do a separate bet on Roxanne incase Barber loses. Let's do a Unit on each bet, 6 units total spend. Return on Roxanne is 7 units, she wins all your other bets are covered.
The Roxanne/Barber fight is not relevant, it's just a way of adding some extra value to juiced odds in Conor, Nasrat, CDF, whoever. Obviously the risk is all your straight picks losing, but if that happens you're a spastic.
Kind of crazy this place, I have a great record and show my bets always and people on here still question everything I say as if I don't get it. 2 losing events in 6/7 months, it's okay guys, I know what I'm doing, which we will see after this weekend when I have another winning event.
