Welcome to the forum....you are not being clear on what you are saying.....yes....offshore books have " in play wagering" .....and they advertise handicappers that guarantee your going to win.....just cause you use their picks doesn't mean your going to win....98% lose longterm! after enough bets....like 500 bets....like one year....2% win....98% lose....but that's only my observation after 56+ years...of working on "both sides" of the sports betting world....(in fact after 500 bets which is approx 1 year of betting...I will lay you 10-1 that you are "loser" big time) with the 11/10 proposition....THAT'S A LOCK!! YOU CAN BET ON THAT!!
Whether you use the sports betting tips or not! So if I finally figured out your original question.... Sports betting "Tips" do not guarantee you are going to win......sometimes they win + sometimes they lose!
