re: Poker & Advice for a first Live MTT appearance
Yes, be aware of the one motion rule (in other words, all your chips have to go into the pot at once. You can't put a stack in, and then put more in, and then more, etc.). And you need to be aware of the oversized chip rule. If the bet to you is 200 and you put in a 1k chip, that is just a call. If you intend to raise, announce raise and the amount you intend to raise to before you put any chips in. And for the love of God, don't say, "I call, and I raise!" The first thing you declare is your action.
Be patient, take your time and most importantly have fun.
