How do you remember basic strategy for blackjack ?

Remember hit 7up. That's it. If dealer shows 7 and up and you don't have at least 17, hit it. Otherwise stay. Some people at the table play free-style blackjack, which is wrong and they may get mad at you, ignore those people. I've been dealing in casinos for 12 years and I've seen maybe 4 or 5 people play strictly that way. They didn't freestyle or anything, they just played that way the entire time they played. They won thousands. It didn't matter what the other players were doing around them, they played their game and WON!! Most of the other players around them lost, they won. Did they get lucky? NO! If it was just once or twice, I'd say yeah, but every player I've seen play pure basic strategy without any variation whatsoever has been a winner.
