if you want you can check Gus hansen´s final table at the Aussie´s . he raised throughout the tournament more than 60% of the hands. Also you can check his video with the all in against the other poker stars. if you need help finding them i can post them here for you.
if you are a tighter player you can raise and show your cards at the end of the hand , just to gain credibility and after that you can extract chips easier.
