Avoiding tells in live tournaments

[betgo]

I generally put a chip on my hand whether I am going to play it or not. I don't say anything while is a hand other than "raise", "call", and "allin". If someone is sonsidering calling me, I sit motionless no matter what. I try not to make motions to my chips or to fold until it is my turn, and sometimes make slight spurious motions to confuse any tell.

When the dealer is counting my chips allin, I try to avoid correcting him. Sometimes I would say something when he was off, but found that was a major tell.

I don't wait until it is my turn to look at my cards. I know a lot of pros do that in major tournaments, but the cost/benefits don't seem worth it in the tournaments I play in.

Are there other things I should be doing or should consider if playing in a major tournament?
