[Riverman]

There is no need to act like a douchebag if you want to have your image help you. In NL games, simply making a few big bluffs early and showing them, combined with always having a drink in front of you (even if you are not drinking heavily) and being friendly and talkative generally can be quite helpful. Just remember that once youve planted the seed you should generally not make big moves because people will be looking to pick you off.
