When adjusting to a loose-aggressive player, it’s crucial to remain patient and selective with your hands. Since these players are likely to bet and raise frequently, you should widen your value range and focus on strong hands that can withstand pressure. Instead of engaging with marginal hands, allow them to make mistakes by overvaluing weaker hands or bluffing too often. You can also use their aggression against them by trapping or check-raising when you have a strong hand. The key is to exploit their overconfidence, while avoiding getting involved in unnecessary pots that don’t offer strong equity.
