Do most Vegas casinos require twice the table minimum when playing 2 hands(6-deck)? Also if you drop to one hand can you spread back to 2 hands? Remember many years ago Texas Station would not allow switching back and forth between 1 and 2 hands.
half and half and many that allow you to play two hands at table min only allow it at $25 and higher tables. I don't know of any casino that doesn't allow you to play 1 or 2 hands as you wish switching at any time...but I'm sure that there are some out there somewhere.
BTW, it is a good idea to play 1 or 2 hands but not switch back and forth based on the count...especially at pitch games. This is a sure-fire tell for surveillence and they look for it.
