Assume you either see a posted line of -150 for a play that you agree with. When you browse the books to place a bet, you find that the line has already moved against you. At what point would you pass on the play? When the line moves to -155? -160? -170? Does it depend on the numeric or percentage deviation away from the value you have originally assigned (i.e. 10% or 10 cents off the posted line)? What about a +150 dog that moves to +140, +120 or +100? Any views on this would be welcome.
