It can be helpful to observe how they bet in order to gain insight into their hand strength, regardless of how cautious or reckless they are. For example, a player mayrummuy be trying to bluff or holding strong cards if they are constantly raising their bets aggressively. On the other hand, someone might only be playing premium hands or be more risk-averse if they fold a lot early in the game. You can get a big advantage over your rivals by modifying your plan of action in light of your observations.
