A real battle of Good and evil occurs anytime a game of chess is played.
Equal pieces, equal spaces.
Differing only in color for a purely aesthetic reason
Because battling forces that are aestheticly similar would be lost on the savagely competitive
So a simple white and brown is implemented
But a simple blink of the eyes can make you realize
Same pieces, same moves just mirrored,
One color does get to always go first, but this had to happen either way, and if you feel bad about going second, just think that you got more time to think about your move, and also to just call the white pieces first next time,  if that kind of a thing matters to you.

The chess pieces themselves have no ability to win the game, they are tools for you to use based on your strategy.
The same goes for good and evil
They have no solidified definitions

A good decision to you, could ruin another's life.
Like chess you must think deeply about your decisions and why you're making them.
If someone told you, the way to play chess was to always flick your piece in the direction you wanted it to go and just have faith it would go to the spot it needed.
Then I would hope you would be open minded to other strategies to find the one that works best for you.

People might argue that there are definitive good and evil decisions in life, but that could be based on the fact we are all humans and you would assume that one humans decision on something is made because it would be beneficial in some way to them, so it is possible to be beneficial to you too.
So similar things are desired by humans, but that doesn't mean they are definitive.
 
So just know and always study your chessboard of life so you're always playing to the best of your ability.
But also remember that chess does have rules, life does not.
So do your own thing
Chess just fit my earlier comparison of this or that and the freedom of choice that lies within.
