Answer # 1

EQ: What is the best way to win a game of chess?

Answer: Personally play against superior opponents as often as possible.
(2) What possible evidence do you have to support this answer?

One of the best ways to improve your game and play better is to simply watch good games of chess. They don't have to be played by grandmasters, as long as you watch enough games, you will eventually pick up on patterns across the board. When this happens in one of your games, because of your experience studying, you will know what the opponent might be planning and be able to counter it. 

(3) What source(s) did you find this evidence and/or answer?

My source was my service learning instructor. When I asked him my EQ, he said it was important to study better player's games, especially if when they have more experience playing than you. He said no matter what level you are at, you can always learn more.
