2 Gate Reaver (vs. Protoss)
The "Two Gateway Reaver" strategies refer to a category of early- and mid-game strategies. All of these openings enable a player to train an army of Dragoons with Range Upgrade and a Shuttle with a Reaver. In this case, the Reaver is used to support the ground forces and not as a form of harassment.
The following Build Orders list various examples and variations of the Two Gate Reaver strategies. Not all are listed.

- This build can also be done after other openings. Most of the aforementioned build orders use a Zealot-Cybernetics Core-Zealot One Gateway opening. For other options, see also
The first Zealots trained in the variations described above can be used to harass the opponent or to defend the ramp. Against Two Gateway Zealot openings more Zealots might be added and the Reaver tech can be delayed. Against Dark Templars, the Observer can be prioritized. However, most Dark Templar openings have a designed attack timing with the first Dark Templar emerging around the six minute mark. In most variations, the Observer will be ready around six minutes and twenty seconds. If the choke point/entrance/ramp to the Protoss main is blocked by Dragoons and/or Zealots, the Dark Templar attack can be denied easily.
Usually, the army of Dragoons and Reavers is used to expand after the first Reaver is trained. The timing of the Nexus is dependent on the enemy's build order. 4 Gateway Dragoon openings are especially effective at punishing premature expansion attempts. In this scenario, the entire build order needs to be adapted. Only on maps like Destination, with its narrow bridges, might an early Nexus be viable.
Depending on the opponent's army, the Dragoon/Reaver combination can be used to gain map control. The higher the opponent's Dragoon count is, the more carefully a player should act.
The Two Gateway Reaver opening is hard-countered by 4 Gate Dragoons on most maps. Other than that, it's considered to be a safe way to soft-counter Dark Templar openings.
This build can also be used to pressure players opening with a Fast Expansion if the Reavers are micromanaged carefully and the first five Zealot rush is defended well. Furthermore, the Two Gateway Reaver opening stands on even ground with other openings like 3 Gateway Dragoon Observers.
A Two Gateway Reaver opening works generally on all maps. Maps with difficult Natural Expansion entrances like Destination support the build, as Reavers can be used easier to defend a second Nexus against a greater number of Dragoons.
