There are good cash game players who do not fit the tournaments and vice versa, but I believe that can happen often when you play against opponents who pay all is:
Play with strong hands and try to be aggressive, do cost you an arrival the river. So you force your opponents to play with technically stronger hands and reduce their loss to bad beats. But be aware, any call in an aggressive move could mean a significant loss of your stack.
I believe that if they play with up to 40 players for the tournament, the first hour will be able to book just play with strong hands and pairs (with pairs below 6, recommend a min-raise pre-flop, somewhere around 2x). After the first hour of play, where we have fewer players, the situation of strong hands starts to become somewhat hazardous to your hopes, by the rise of the blinds and the game starts to become more concentrated, with average hands can be played calls only.
