For those of you that track hands and really follow through on developing a large enough sample, you may find (as has been reported here and elsewhere) that the number of "miracle" cards that hit on the turn or the river falls outside the standard deviation on certain sites such as PokerStars. In those cases, if you can afford it, please compile the data and submit it to an independent party (such as PokerPlayersAlliance) for review. This is really the only way you are going to be able prove your case. As a significant player on various sites (I now prefer to play on Ultimate Bet as these bad beats have not been my experience on this site), I can say without a doubt that I have seen the "non-random" results at PokerStars myself after playing thousands of hands. Please also know that PokerStars employs people that scan the forums to rebut any decent argument so do not be surprised if you see an immediate rebuttal to this. Play at safe sites or in live games that you can trust.
