I am not sure about anything. I play in the 30 and 50 dollar hold'em single table sit and gos. I have won a little over $1000 in the past couple months, but I sense I should be winning more. I recently placed 4th (just out side the money) in 14 out of the last 20 tournaments I played in. This sucked, but it is NOT outside the realm of possibility, but it is HIGHLY unlikely. Things like that kind of make me wonder. But then again, I will occasionally win 3, 4, or even 5 tournaments in a row. As for the apparent propensity for a bad luck streak to strike after a cash out, I am not sure. However, I would venture to guess that the reason people cash out in the first place is because they were just on a good luck streak. Luck runs in streaks, and what goes up must come down. As for hackers or party poker cheats, they probably exist, so I guess you just gotta be that much better.
