Freeroll are a good thing but...Most of the players play crazy,a lot of fish playing bad cards and get lucky on the flop,etc.For example i had and AA i go all-in and i lose vs 6-2 or something like that,so off course you get pissed off.Another bad thing for me is that because freerolls dosen't have a buy-in most off the people play very aggresive because they dont have something to lose,and so the playing is pretty diferent from a regulr tournament.The bright side is that u still can lear a lot from this kind of tournaments and you can win some money,of course small unimportant amounts but it is something.I ussualy play freerols when i dont money and i dont want to play chips.
