First of all, I look at what cards my opponents are playing with and I also pay attention to how they place their bets. I always make notes where I describe the important points in detail. For the first 20-30 minutes at a new table, I play very cautiously with strong cards only, and all this time I'm watching my opponents play, collecting important information and making notes.What do you observe about your opponents when you have just entered a table where you have no information about your opponents?
