If I haven't played with a player before and I don't know anything about them, the more they tell me about themselves, the better I will be able to judge how they think and how they play.
Too many players focus on physical tells. For both online and live games, you should be focusing more on betting patterns and histories. The ability to figure out your opponent's hand based on his betting pattern is a crucial skill.
I was very curious, that's why I think my reality TV seems normal. I watch a lot of reality TV because I am so interested in people and observing people. From a very young age I can remember watching a woman with a guy and she's rolling her eyes and he's pleading with her and I would think, she doesn't want to be with him, he's in love with her, she likes this other guy and I would make up these stories in my head about these people. That helps me sort of profile people and that is a key to being able to read people.
If you call a hundred dollars but have a chance to win $10,000, those are excellent odds if you are at a table with people who have two aces or two kings. If you catch a flop you will get all their chips. I just play them because there is value.
