Poker
Poker is about understanding people—reading subtle, tiny cues that even they don't know they're giving off. Empathizing for a purpose. Becoming each of the other players in turn, until you can make a bet with reasonable certainty.
Everybody has a tell.
Her game is conventional, cerebral, calculated. She's not risky. She'd rather fold than take a chance on an unstable bet. The problem is, unstable is part of the cards he's been dealt, and he can't change his hand. He can only play what he has. Her caution is her tell.
He's a bold gambler, willing to bet big, less willing to absorb the consequences. His people are his cards; he's a bad bluffer. Being part of that hand is unspeakably dangerous. He only knows how to play until he wins. His perfectionism is his tell.
She's too young to play well, he thinks at first. But she stays in the game, somehow, white-knuckling her way through round after round, scraping by with enough chips to stay alive. But she has cracks around the edges. She holds her cards to her chest until they fall one by one, dropped by her weakening grasp. Her fear is her tell.
Too easy—that's what she is. So many clues they're overwhelming. Her transparency is her weapon. She can be used, but in the using, she will take what she can for her own purposes. She has a keen eye. She can conceal nothing, but nothing can be concealed from her. Her eagerness is her tell.
He's the consummate Poker player. His every move is calculated to seem uncalculated. He plays with a deliberateness that belies the passion burning underneath the surface, and he plays to win the whole game; even lost rounds somehow seem like victories to him. He has no tell.
