from $0 to $200 - my little 2 cents on that matter
It is possible, I did it myself during this last 3 or 4 months. First of all, I'm a very conservative/tight recreational player, who just started to really learn the game in those last months, and I play only on pokerstars (till now, but I'll try
888 next).
They had those Ronaldo, Neymar freerolls for a while and I was lucky enough to cash on 2 of them ($9 and $12). Then I started to play 0,27 tournaments and cashed big one time ($81). Now I play $0.25 sit 'n gos and $0.55 tourneys.
I don't know if what I'm about to say is the standard lesson on how to win freerolls or microstakes tourneys, but i just was playing really old school poker, waiting for nice spots, folding a lot, making notes on the weakest players etc. You only can beat bad players with good old proper poker, and you know, 70%, 80% of those fields are composed of really crazy bad players.
So, thats my experience on that subject... But if I had to start again, knowing what know by now, I would try just PLO freerolls. Yes, Omaha is a game of high variance, yep... but trust me... you will be the only man with eyes on a jungle full of blind animals. You will be king
Good luck!
