Is there any way to relate chess to real life friends? Yes, there may be a way to relate it. For example lets say there are strangers out there you just met. You don't know their intentions. Therefore, you have to figure out how many moves ahead they are compared to you. In chess you can be advanced and ahead of your opponent by four moves or more. In life, it is relatively hard to be ahead of a person by as many as 2.
