A BETTOR must lay 11/10 when making a bet, this is called the Vigorish, Vig, or Juice. If you bet $100 on a team you must pay $110 to win the $100... you only pay the Vig if you lose the bet. The 11/10 edge of the bookmaker means if you are hitting games at a 50% clip that you are losing and the bookmaker is winning.
