When I have a lot of DC bets that keep getting picked off by a 'hot(read:lucky)' shooter, I will pull the lay odds down and Place whatever Don'ts still reside. Let's say those were the 4,5,9. During his throw, I then place the 6/8 and he hits his point of 10. On the C/O, I would want the Place bets for the 4,5,9 Working, but not the 6,8. What I have seen the dealers do is simply move the 6,8 Place bets into the Come area and ON the 4,5,9.
