I was sitting to play before. NoW i start WONG-IN and OUT. when i see somewhere is shuffling, then i go over there, just sometimes wait for a delaer to finish a shuffle and change cash for player still waste time. SO, i start to walk around, when I see some TABLE has alot of cards on ( 3,4 or 5 in a row. that means so many small cards out) then i start COUNT quickly. Get the running count, and take the used card back to the end of the shoe. as long as it is over Ture 1, then i JUMP in. IS it safe? many unknown cards out before, but save alot of time....
