This was an interesting episode with a lot of foreshadowing. First we see Beth become physically closer with Beltik, but then she deflects when he tries to tell his deeper feelings to her (this may possibly be a reference to a scene at the beginning and a mentality Beth holds, in which her mother warns her never to trust other people). I found it strange that Beth reads a lot of books about chess yet refuses to look at the games played by Borgov; she states that she could beat him with a little more practice, but she later admits that he easily beat her.
I like the small cut to the interview with Borgov. He stated that he plays against people half his age and that he doesn’t know how long he can continue winning for; this is a nice moment that humanizes him after Beth previously described his robotic, straight-forward chess-playing style.
The moment where Henry warns Beth not to become too passionate and out of control, and another moment when Benny comments on her heavy drinking, seem like obvious foreshadowing for the route Beth is going on. I find it ironic, not in a bad way, that Beth is extremely intelligent when she plays matches but cannot foresee her own spiraling.
