FreeRoll opinions

I Play lots of Freerolls and have seen many styles of play wether it be fast and lose or tight players who pick their battles and only play premium starting hands. Though these players tend to stand out and are fairly easy to pick out on the tables. I seem to have the most problems with the unpredictable or hard to read players as you cant seem to get a handle on how they play or what they are thinking. The worst among these players are the fat stacked players that tend to push you off your hand with what would amount to an all in bet for you with what could be a marginal hand, top pair good kicker for example, but you are forced to fold to preserve your small stack to continue on in the game. I started this thread to get different opinions on freeroll play styles , what works best for you? Maybe this thread will give us all some new ideas on how to approach this type of game.
Thanks for sharing.

There's a current thread on this ongoing... How to win in the freeroll tournaments?
