On my last trip to Vegas, I noticed that most casinos had the H17 rule for 6+ deck Blackjack games. It seems like a very minor rule but it does give a slight edge to the house. I found a website that gives you the lowdown on what the H17 rule means to you and how you should play your cards to maximize your odds.
