How can I smoke chicken breast to enhance its flavor and tenderness?

To enhance the flavor and tenderness of smoked chicken breast, marinate it in a flavorful mixture before smoking, use a dry rub with herbs and spices, smoke it at a low temperature for a longer period of time, and baste it with a mixture of oil and herbs during the smoking process. This will help infuse the chicken with delicious flavors and keep it moist and tender.
