To avoid being predictable, it's essential to mix up your play by incorporating randomness and unpredictability into your decision-making. This can be achieved by varying your betting patterns, such as mixing up the size and frequency of your bets, and by balancing your range with a combination of strong and weak hands. Additionally, you can add unpredictability by occasionally deviating from your standard lines and playing unconventional hands in unexpected ways. By introducing randomness and variability into your play, you can make it more difficult for your opponents to read your actions and anticipate your next move.
