Handling an unpredictable player at your table requires a combination of adaptability, patience, and careful observation. You should focus on identifying patterns in their play, if any, and adjust your strategy to minimize losses and maximize opportunities. This may involve tightening up your starting hand selection, being more cautious in certain situations, and looking for opportunities to exploit their impulsive or aggressive play. Additionally, maintaining a solid table image and avoiding getting frustrated or emotional are crucial in dealing with unpredictable opponents.
