This may sound strange but why not train yourself to be more aggressive, if you are playing in freerolls then what have you got to lose, i occasionally play "reverse poker", it's a game i invented where the object is to annoy as many people at the table as possible by playing the worst hands and winning. Yesterday i called a 2xBB raise with 53 of clubs, flop came 5 K 5, i checked and the guy on my left raised big, i re-raised all-in, he called and turned over KJ.
Now the idea of the game is not to donk off your chips but to improve your skills playing marginal hands, learn about bluffing
and to practice being aggressive.
I know this seems a sick strategy but the reason i invented this game is to teach myself to play more hands and be less passive, i have no fear now and when playing wild and loose you will find the other players do not want to play against you, your blinds will be folded more often and the pots you play will have less players, IF you can play this way and win chips they will fear you, IF you cannot fold then you will spew chips.
Now i don't play this way all the time and when i do i do not play just any two cards, i play hands that have a chance to win, i play hands like 53 suited and my personal favourite is 97 suited, but i will fold unconnected hands J4 etc. even if suited.
The way i start is to be a calling station, playing as many hands as i can (suited 2 gappers like 69, any A) but being very passive after the flop if i don't hit hard. It is not easy but if i accumulate a few chips playing this loose passive style then i will change into a raising machine, i will not limp and will raise with a wide range of hands, making continuation bets most hands i play.
It is a strange way to play but it helped me a lot, how to disguise my good hands, how to fold, how and when to bluff, how to use chips as a weapon, how to play the player not the cards.
I get called bad names quite often but i originally started playing this way because i was sick of bad beats and i wanted to dish some out for a change.
I think i may get roasted for even suggesting you play this way but as previously stated i get called bad names quite a lot and playing like this helped me get through my nit phase.
