Catan's robber mechanic creates its most interesting decisions when used strategically rather than reactively. Playing a knight card to move the robber is optimal when you can target the player most ahead on victory points rather than the player who has a resource you want. The long-term value of handicapping the leader exceeds the short-term value of stealing a single resource.

The largest army bonus requires three knight cards to claim and two more to reclaim if stolen. Racing for largest army requires holding knights rather than playing them, which creates a tension between knight card use and largest army accumulation. Players who play knights reactively for robber relocation rarely accumulate enough to claim the bonus.

For experienced Catan players teaching the game: explicitly discuss the difference between reactive knight use and strategic knight use. The robber as a tactical tool rather than a nuisance response is the game's deepest strategic element.
