statistical tests to show that online poker is not rigged

You could try the "Integrity" page -- they don't have literal published tests, but it certainly looks promising when you use hardware RNGs (not the pseudorandom, "seeded" software RNG that most home microcomputers use), which are officially verified by two security firms -- including one which hacked an online poker site in the past!

(Incidentally, I wish they did something kind of like PokerRoom's EV chart at http://www.pokerroom.com/games/evsta...php?order=card )

Seriously, the "OMG STARZ IZ RIGGED!!!1" people need to quit whining. No one seems to realize you hit an 80% shot, oh, say, 80% of the time. (which, honestly, is why I usually play limit poker)
