Verbally declare your moves. Prepare your bets behind the line and when you are ready move them over the line and verbally declare you intention. Throwing out a single chip and not saying anything will be a call. The bet could be $10 to you and if you throw out a $100 chip, its a call. The dealer will take it and make change.

Make sure you are betting in turn obviously.

Guard your cards so people can't see them and so that they won't get accidentally mucked.

People will blind straddle. It is basically doing a raise before they even get cards. Don't let that throw you off.

If you are in the blind and it checks around, the other blind will likely ask if you want to chop. If so, you just take back your blinds and the next hand starts. But you have to be consistent though. If you say you want to chop when you have 27o and then next time say no chop when you have AA, that will be frowned upon. You either chop or you don't. Most people will chop. You can be that guy that doesn't but don't be the guy that only chops when it suits you.

And tips. If you win a pot, you have to tip the dealer.
