If you play the 25+ or the one for all members on CardsChat you have no reason to worry for other freerolls , they are simple the best
.I play them tight aggressive and wait for the right spots to raise the pot and earn some chips .
But if you play other freerolls with 4000 or more participants , it really depends on many factors . Like on the chips you're starting with (the less chips you have the more loose you are forced to play ) , if you have doubled/tripled early your stack (so you can play more hands of a wider range from more positions ) , the blind levels duration (the more time you have until the next blind level the more you can play TAG and 10% or 15% of your range , but it all has to do if the others are very loose or TAGs on the table so you adjust your style , with loose aggressive I play TAG (you are carefull with the garbage cards they play) , but with TAGs , TAG and semi loose , some hands cheap I limp if I can or I mini raise , in position , to steal blinds etc ,
) . That's how I play .
