I've got a game here that is $5-$100, $25-$500, 4 deck, riffle shuffle, with all the good rules except hit S17, ES against anything but an ace! Penetration varies by dealer (law is something like 32-104 cards, those dealers that like dealing rather than shuffling are closer to 32; others are 104+ (I've challenged)).
I believe these rules are available elsewhere in Alberta (including the "dream" Calgary Stampede rules in another post).
Looked at the shuffling techniques, and I think they may be trackable.
Upside, if you are carefull - probably no heat, bad dealersl Incorrect payoffs etc.
Downside - a significant portion of the profits go to charity (by law). If you rape the casino, you are raping the charities, some of who I support. (I've worked casinos; if anyone wants to know why & what, let me know)
As a BS player, who is about even, I'm happy (good entertainment value).
However, as a greedy SOB, I might even practice CC!
