The greediest standard TvT opening — a command center at 14 supply before any military production. This sacrifices early defense for a significant economic advantage, banking on the rush distance being long enough that any aggression arrives after you can defend.

Build the command center at your natural or inside your main, depending on the map. Follow up immediately with a barracks and factory. The critical window is the period before your first siege tank — if the opponent attacks with early marines or a factory rush, you may not survive. Once your first tank is in siege mode, you are safe and ahead economically.

14 CC is standard on large four-player maps like Fighting Spirit where rush distances provide natural safety. It is strongest against opponents who also choose economic openings. Weak against proxy barracks, early factory aggression, or any build that hits before your first tank arrives. Transition into standard tank-based TvT warfare with an economic lead.
