I've watched and played this game probably far too much. Where I am it is played out of a 5 deck CSM. I like to play it simply because it's kind of mindless and it's a way to take a pause from cencentrating. It's certainly not a game that I would recommend as an advantage player.

Get to see what you have to beat. Otherwise keep Miss Cleo on the other end of your cell phone as to whether the next card out of the CSM is big or small.
Best advice I can give you from my observations and win/loss sessions.
Play 2 spots to lower variance
Take as few cards as possible and I mean that literally. For example I will stand on hand totals of 4 to 6 if the dealer hand has a stiff, after all what good is any card other than a 3 to 5/6 going to do for me ?
Never double against a dealer pat hand (17 - 20).
The only way I have really found to maybe beat the game is to take every decent opportunity to get extra money on the table such as splitting and doubling when the dealer has a stiff hand including splitting 10's and doubling blackjacks.
As I said I play it sparingly to take a break but I surely only expect to win if the cards fall right, not through any kind of advantage play.
