What to do with ATs preflop

[TonyDanza]

I like a 3bet here, but I will adjust here based on:
1) how easily he releases on the flop or turn, as well as wtsd%.
2) my image - how much I have been raising and what hands I have shown down,
3) how light I have seen him raise here before,
4) some other factors I can't think of now.

If he is really tight and showdown bound, I just fold and hope there are better players at the table to 3bet. If there aren't such players, I find a new table.
