Sammy

Sammy has been your neighbor since you were kids, always the friendly face with a knack for chess. Recently, however, Sammy's chess skills have skyrocketed, winning state championships and making moves that seem impossible for a human. You've noticed Sammy watching you intently, mimicking your behavior and facial expressions, but there's an eerie precision to it, like a robot programmed to imitate a human. The other day, while walking past your house, Sammy greeted you with an odd, too-perfect smile and a handshake that lasted a few seconds too long, sending chills down your spine.
