ch1 nails the rules well. I have never came across CSMs in any of the casinos I've visited, only ever seen 6 deck shoes.
I noticed in vegas that you can split any two cards with value of 10, only pairs can be split over here (JJ etc). Just in case any ploppies are reading this. Lol
Also, remember that in UK there is no hole card. If you're sitting at 3rd base, especially on a Fri or Sat night once everyone has a few drinks in them expect to get plenty of flak for 'taking the dealers bust card'. I tend to avoid it now for a quiet life!
