i have to agree with previous poster, it's about stack size vs bba amt's, say you have 5k left and bb/sb at 1000k to 1500k, you will have to play for life and death and go all in with the best possible hand, vs you have 20-25 k and you raise with pretty much any pair, suited connectors to make the smaller stacks to commit all in to risk tourney life or fold, give more details in your scenario..
