Very simple to determine this although i need to rack up some points here so ima type a bit

. A freeroll obv is a freeroll which means that anyone can sign up, which means they dont really know how to play. I cant tell you hwo many times i see people just go all in with nothin, nothin draws and just plain old NOTHIN! It happens. I played in
PokerStars freerolls when they could have 15000 people in them, 15000!!!! I dont know if they're still doing that but that is just crazy. Anyway it ended up being like 14155 or 14200+ people in this tournament and i came within top 100. My secret? Tight and aggressive like my buddy lytspeed said. Problem is the fact that people most people dont have a CLUE at what they're doing when they play freerolls so they just go crazy. If a table is loose then you most definitly need to trap and play tighter than a virgin. I did that and was getting far. Also never worry if someone has more chips than you and what not just focus on your own table, your own chips and the current hand at play. That could lead to the dark side of the force! Usually the people who are smart and know what they're doing will end up going the farthest in the tournaments. Now as of buy ins... told ya this would be long :P. Obv if a person has the money for a buy in they have to know atleast a bit of what they're doing and you dont see them go all crazy and what not... unless its like a 1$ buy in. But typically there will be smarter players at this type of tournament rather than a freeroll. This gets tricky because there are still people who dont know what they are doing on tables and some people who know EXACTLY what they are doing so tables will differ. Depending on the table you will have to change your style, but nevertheless play great poker and make great reads. Obv if the table is tight you want to be looser and winning small pots frequently and building up your stack. Or if the table is loose than play tight and wait for the hand and trap a guy. Either way it works beautifully. When players start to realized about the style you are playing.... change it up

Just keep them guessing. Great line from a poker book i read from David Skslansky. If a player would play a hand as if he didnt know what YOU had, you will win. If you keep on mixxing it up they will never know what you got and will be stupid and sometimes just call you down with A high. But i'll leave that up to you
