A plate of chicken is a good meal before games because it has much energy.
In fact, the best meal before games should have carbohydrates(碳水化合物). Foods like potatoes, bread, bananas are rich in it, chicken and meat are not. Carbohydrates are the best and most easily used forms of energy. The energy that you get for today's game is from what you ate yesterday.

Exercising the same body part every day is the fastest way to improve strength.
