It is advisable to fold when there is a strong possibility of getting a better hand, such as flush or full house by folding. Whenever your opponent bets continuously using suited cards on the board, it is often wise to quit. Similarly, folding a flush is recommended when there’s a higher flush (especially when you hold a weak flush) or when a full house is possible. In both cases, discipline is key. Overvaluing either hand, especially in multi-way pots or against strong opponents, can lead to significant losses.
