This build order is an aggressive 2 base all-in played by Russian BioTerran player Overpass. As an opening he uses standard version of 2-1-1. Playing 2nd Supply before 2nd Gas is the safest TvZ doubledrop build order, therefore it is much more preferable for ladder games and BO1 matches. The transition after 2-1-1 is placing the production of: 5 barracks(4 reactors, 1 tech lab marine production), 1 factory on reactor (Widow mine production) and 1 StarPort for medivac production without add-on. The all-in is played on approximately 33 SCVs and in most cases has no transition into later stages of the game. The timing of sending the main army to attack is 6:30. It is very important to stick to that timing to get the maximum efficiency of this build.
Why is there no SALT encoding or Overwolf build?

However build order is highly micro dependent and might be difficult for beginners, it has extremely high potential to make the most of the Mid-game and finish the set with a victory. As most Zerg players in the current meta have a decent experience of playing versus the 2-1-1 builds, it is crucial to micro very well during the whole game and get the maximum efficiency of your units, including scouting Reaper. 2-1-1 has always been weak against Ling-Bane all-ins, so it is essentially important to get the most efficient scout during the early game in order to have enough time to get ready to defend.
