This is the September 2019 entry of Metagame Build Orders.
Recently, there is a metagame shift in the Terran mirror match up openings. This post discusses how different openings interact with each other, and how that leads us to the current trend.
Some readers asked me for an updated version of the one build for three match-ups I posted previously. There is also an increase in demand for beginner builds on /r/allthingsterran recently. This post covers builds for beginners and intermediate players.
