21 Personalities
Vectron never plays a genuinely bad move. Each personality only expresses itself among the moves it already rates roughly equally good, biasing which good move it plays, not whether the move is good. Pick one to challenge, watch two face off, or just get to know their styles.

How Personalities Actually Work
No Bad Moves, Ever
The underlying engine has no built-in concept of personality. For every move, Vectron asks it for its top candidate moves within a small tolerance of the true best line, so a personality can never pick an objectively bad move. It can only bias which good move it plays, based on move-feature weights like piece type, distance to the enemy king, centralization, captures, and checks.
The Rivalry Triangle
When two personalities face off in Vectron vs Vectron, a rivalry system kicks in. Every style leans toward aggression, maneuvering, or caution, and the triangle counters itself: aggression beats maneuvering, maneuvering beats caution, and caution beats aggression. A personality with a natural style-counter over its opponent gets a slight tolerance boost.
