Since the blinds go up in a tournament the action is necessarily forced to be faster. Read this excellent article
about the differences between cash and tournament play.
Here (http://www.cardschat.com/f13/passing-some-advice-paul-wasicka-gave-me-along-88168/) is a thread where Paul Wasicka tried to answer a similar question. I particularly like this quote:
"Tournaments you are usually trying to put pressure on and get your opponents to fold their hands to you. Whereas cash games you are typically trying to hit a better hand and get paid off."
