I live in Alberta, so I can say there are some inaccuracies in his post.
First of all there is no early surrender for the high limit tables.
Second the penetration is BAD at the 4 deck places.
Third if you are winning you DO GET HEAT, and if you don't take a hint there is a good chance...
Games aren't that great anymore. Recently I have noticed casinos have less tables open then they normally did, so you always are playing at a full table. And the penetration is bad.
For all high limit BJ in Edmonton casinos (except Palace) there is no surrender. No surrender = waste of time
Palace Casino had surrender, but it has 8 decks and bad penetration, which also makes it a waste of time.
