PvT 2 Gate Fast Obs FE

Overview

Possibly the safest opening available in the PvT match-up. The idea behind this opening is to quickly get out an Observer before laying down a Nexus at your natural expansion. The Observer can then be used to scout what the opponent is doing, allowing you to react accordingly.

Basic Build Order

2 Gate Fast Obs (vs. Terran)

9 Pylon 13 Gateway 14 Assimilator 16 Pylon @100% Gateway: Cybernetics Core, Zealot 21-22 Assimilator (2) 21-22 Pylon @100% Cybernetics Core: Warpgate Research, Sentry. @100% Sentry: Stalker @200 Minerals, 100 Gas: Robotics Facility @150 Minerals: Gateway (2) @100% Robotics Facility: Observer @400 Minerals: Nexus @100 Minerals: Pylon When the first Observer finishes, either build a second Observer or an Immortal. Build the Immortal if you suspect Barracks pressure and the Observer if you suspect Cloaked Banshee play.

Scouting

• You can scout either after the first Pylon or after the first Gateway. This is completely down to personal preference.
• If you scout that a Marauder is being built by the Terran player (or you scout a Tech Lab attached to a Barracks) then it is possible to get an Immortal before the first Observer. This will make this opening safer against the early Barracks pressure that Marauders usually signify.
• Assuming you build the first Observer as described, your first Observer should reach the enemy base before your Nexus finishes. If you see no sign of a Terran expansion then you should cut Probes ~30 and begin building up units ready for their all-in. If you do see an Expansion being planned then you can continue on with whatever Tech path you desire. Colossi are a good option as you already have a Robotics Facility.

Counters

Counter To

• 2 Rax Pressure-Builds: You should have more than enough units to prevent the opponent from being able to pressure you at this timing.
• 3 Rax Stim-Timing All-In: By being able to scout the opponent's build with the fast Observer, you should be more than ready to defend your base against any attempt at an all-in.
• Cloaked Banshee Openings: You will have two Observers out by the time a Cloaked Banshee opening hits. This should mean that you will not take any damage from their opening.

Countered By

• 1 Rax Gasless Expansion: The opponent will get ahead of you economically if they go for a fast-expansion against this opening. A good transition if you scout the opponent fast-expanding is to go for a 3 Immortal Timing-Attack.
