While reviewing the comments/answers to the question, I took the liberty of recapping some of the better notes in the thread.
⦁ Difficult to bluff a fish that doesn't know when he should fold. If he has top pair & bottom kicker he thinks he has gold. So do NOT bluff a fish, they won't fold.
⦁ Freeroll is very long, and you must be patient
⦁ I would play tight and if I had a monster hand, such as AA, KK, QQ, and AK I would all-in and still position is important because for sure at least one person in your table will shove with you.
⦁ Be very selective in the opening levels and very aggressive when you play.
⦁ If I have one of the top five hands I would go all in or just keep betting about 5x the pot.
⦁ For large Freerolls, be patient and ready to go the long run... some games can last 3 or 4 hours for a $12 payout. Is your time worth it?
⦁ Not every freeroll is a nothing game and Cardschat ones are the best, there aren't always people that go all in in these tournaments.
⦁ But,if you are referring to freerolls at
pokerstars where there are more than 5,000 or 10,000 people in them,then it's often a waste of time playing in those.
⦁ On PS there is tourney called PokerSchool. I played about 2-3 hours and won ~$0,5$. Other sites offer better freerolls like ACR.
Thanks to everyone for their input.
