TvZTerran vs Zerg
Take two bases, build more barracks than feels reasonable, keep marines and medics streaming, and make siege tanks the moment you see lurkers.
Three-hatch hydralisk
ZvPZerg vs Protoss
Three hatcheries and drones, hydralisks with speed and range to stop the first push, a fourth base behind lurkers, and hive tech before Protoss has its third.

PvTProtoss vs Terran
Expand faster than Terran, keep dragoons and zealots streaming from many gateways, see the mines with an observer, and win late with arbiters or carriers.
