This is my oppinion based solely on my play at
poker.com. The freeroll tournaments and the
poker.com sponsored tournaments are setup so that players get eliminated. Often times, that means if you go all in against someone who has more chips than you, you are more likely to get busted. Afterall,
poker.com is not making money from your game play when you are playing a free roll.
This is not the case in rake games. I have found that the raked games are reasonably fair.
Just my two cents.
