For a moment, I thought you won 4200 dollars... but 500 bucks is still pretty good for 3 hours work. That's like... better than lawyer wage if you can do it consistently.
No doubt. Luck plays a bigger factor on-line than it does in real life. But, since alot of on-line winners are winning in big casino events .. it shows that they can still be great players.
Yep. But you have very distinct betting patterns when doing this. Alert players can report you and the sites are pretty good at checking your recent games and banning colluders (and seizing their funds).
It's difficult to execute well, but it's possible to do it without getting caught.
The best way to protect against this is to:
A) Play lower level games. The risk-reward ratio in lower-level games is way too high for serious colluders to risk playing. As for casual (can't think of a better word) colluders, they won't be good enough to damage the game. If anything, you'd be able to exploit them.
B) Play exclusively in tournaments. Your seat is randomly assigned, so nothing to worry about there.
