The key to correctly interpreting body language is to pay close attention and observe carefully. Make sure you are aware of details such as posture, gestures, facial expressions, and other minute movements that will give away clues as to what your opponent might be planning. Additionally, developing a strategy based on your own intuition and knowledge of the game can help you anticipate your opponent's moves before they make them. Knowing what your opponent plans to do ahead of time gives you the upper hand and can increase your chances of success in any given match.
