Rpm,exactly the same.But ona win bet you are playing on house money.An if lose you are chasing.Lucky,prefer to remain in the shadows.Not on screen and not on line.Someday maybe.
So wouldnt one be playing the dog to lose. If the dog was big enough, doesnt that tend to make an "if lose" wager easier. Judge states the players lose & are chasing. I have never thought of the scenerio. Learning each day.
I tried an if lose bet last year at Jazz, so I know they take them over the phone. I am sure there are other books that also take if lose bets, you just have to ask. Good Luck.
