calling pot sized bets with straight and flush draws is not justified by the pot odds ever and it will happen quite often on any online poker site. Going all in and getting called by a better hand and then catching on the river is just getting lucky trying to bluff at a pot which is completely different and happens in live card games as well. I understand the straight and flush draws will catch by the river around 30% of the time, but anybody that has played a significant amount of online poker would probaly aree that you will see many more flushes and straights than you would in a live game in spite of how many more hands you play. I think that there is something to say for the theory of draws coming up on the flop to generate action and therefore increase the rake. You have to admit that at times it seems that every flop has two of the same suit. That being said the sites can't rig idiot players calling raises with any two suited cards or hands such as 9 10 offsuit. It is and will continue to be a hazard of interenet poker play regardless of what site you play at.
