A lot of people who think online poker is really rigged (imo) do not play tons of poker (thousands and even tens of thousands of hands every week). I play live, about 4 hours per day on average (4 or 5 days a week). That's not very much. But when I used to play online, I played many more hours than that.
While I was watching the WSOP last night (saved on my PC), I thought, gee, I've played in tournaments with as big of a field as that. The only thing was it only took me 8 or 9 hours to play.. not 4 days! Imagine the bad beats and tough hands these people have seen over the 4 days.. and then compress that into just 8 or 9 hours. That's a huge time difference!
And that's what I don't think people who think online poker is rigged realize. I know it's been mentioned already (many times), but maybe if these people just played more, they would see their losing streaks even out. And maybe they might actually have a few good runs, too. That's if they're not donks with their chips (which I think most are).
Just another 2 cents in the bucket
