The money you place or lay on the table can be turned off or pulled down, anytime you like. Of course, the primary reason to do this is that you feel/sense the 7 coming. So turn em off and make a come bet. Or make a few bets on big red. And there is no better advice than standing and watching a few decisions. I like to see 3-5,unless there's on obvious trend. Live craps record really helped me get the whole thing together, by being able to see the roll trends build, and identify hot/lucky shooters.
