I've decided that I believe there are "patterns" to the cards in some ways, but not in a way that should affect how well players do. These "patterns" don't allow you to predict the cards or anything; I just think the algorithms create chains that you can see. For example, many MANY times I'll be playing several tables and get very similar hands at each one, that kind of thing. It's just the way the program works. I think it's still "random" for all poker-playing purposes.
