--- Start of scene ---

** Harold sits alone at a chess board in Battery Park, New York, on a cold day **

Man in dark jacket:     "Hey, man."

Man in dark jacket:     "So you wanna play, or what?"

Harold:                      "Oh, that's very kind of you, but I'm playing with a friend."

Man in dark jacket:     "You've been sitting here alone for hours, dude."

Harold:                      "My friend is a little shy. And somewhat indecisive."

** Man in dark jacket walks on **

Harold:                     "I thought you wanted me to teach you how to play."

** Harold looks at his phone, expectantly **

Phone display:          > _

Harold:                     "Each possible move represents a different game."
Harold:                     "A different universe, in which you make a better move."
Harold:                     "By the second move, there are 72,084 possible games."
Harold:                     "By the third, 9 million."
Harold:                     "By the fourth -- "

** Phone vibrates **

Phone display:          > Incoming SMS: "318,000,000,000"
                               > REPLY? _

** Harold nods, puts phone away **

Harold:                     "--there are more possible games of chess than there are atoms in the universe."
Harold:                     "No one could possibly predict them all, even you."
Harold:                     "Which means that that first move can be terrifying."
Harold:                     "It's the furthest point from the end of the game, there's a virtually infinite sea of possibilities between you and the other side."
Harold:                     "But it also means that if you make a mistake, there's a nearly infinite amount of ways to fix it."

Harold:                     "So you should simply relax, and play."

** Harold reaches over and moves a pawn one square forward **

The scene is revisited towards the end of the episode, which shifts the intended purpose of the analogy to become something else:

--- Start of scene ---

** Once again, Harold is in Battery Park, sitting by himself at a chess board **

Harold:                     "Yes, yes, you needn't rub it in."
Harold:                     "One afternoon and you're a Grandmaster."
Harold:                     "Mind you, you'll encounter far more capable opponents than me if you go looking."

** Phone vibrates **

Phone display:          > Incoming SMS: "Once again?"
                               > REPLY? _

Harold:                     "No, I don't think so."
Harold:                     "You asked me to teach you chess and I've done that."
Harold:                     "It's a useful mental exercise."
Harold:                     "And through the years, many thinkers have been fascinated by it."
Harold:                     "But I don't enjoy playing."
Harold:                     "Do you know why not?"

** Phone vibrates **

Phone display:          > Incoming SMS: "No"

Harold:                     "Because it was a game that was born during a brutal age, when life counted for little."
Harold:                     "And everyone believed that some people were worth more than others."
Harold:                     "Kings and pawns."
Harold:                     "I don't think that anyone is worth more than anyone else."
Harold:                     "I don't envy you the decisions you're going to have to make."
Harold:                     "And one day I'll be gone, and you'll have no one to talk to."
Harold:                     "But if you remember nothing else, please remember this."
Harold:                     "Chess is just a game."
Harold:                     "Real people aren't pieces."
Harold:                     "And you can't assign more value to some of them than to others."

Harold:                     "Not to me."
Harold:                     "Not to anyone."
Harold:                     "People are not a thing that you can sacrifice."

Harold:                     "The lesson is that anyone who looks on the world as if it was a game of chess deserves to lose."
