TvZ: 2 base 5 factory push

The idea of it is to get 2 bases off a 1 barrack expansion.

Afterwards, you immediately add your first gas and add two factories, academy, and engineering bay.

The key of this process is you must NOT show your factory. He must think you are opening bio. The ebay is used to counter mutalisk or lurker (for detection). The academy is built for scanners to see what tech tree the Zerg is going. Also, it gives Zergs the false impression you have opened bionic, as an acdemy is necessary for medics/firebats.

However, with the initial two factories, you will either build goliaths to fight off mutalisk or tanks to fight off lurker. In fact, lurker opening seems really easy to fend off

Upon mutalisk entering your base or discovering he is going to attack with lurker, you add 3 more factories and go for a timing attack when not only his 3rd just kicks in, but also when he starts to add in hydra or mutalisk.

Build Order:

• 9 supply
• 11 barracks
• 15 supply
• 19 command
• 20-21 gas
• First factory upon first 100 gas 
• Second factory upon next 100 gas
• When first factory is done, add add-on and upgrade charon boosters.
• 34-35 engineering bay
• Academy + Armory when factory is complete 
• +1 armor upgrade (mechanic)
• After 6-8 goliaths, add 3 factories (and add one more machine shop)

**NOTE**: I suggest making bunker and sim citying for ling runbys. Also when academy finishes it is okay to make 1-2 firebat for your bunker to prevent any ling attacks. MAKING MARINES (USUALLY 8-10) WITH SIM CITY AND BUNKER HELPS PREVENT LING RUNBY DAMAGE. REACT FAST WITH REPAIR!!![

**NOTE#2**: Make vultures+mines before you push out so you can place mines around areas where he can come around and backstab you..this is my biggest weakness with this build.

**NOTE#3**: Add second gas when you are sure the overlord can not see your second gas being built. Making it too early gives him the impression that you are going mech, which will give him the chance to adapt faster. You are trying to avoid that and fake bionic as late as possible...

Follow-Up:

If he opens mutalisk...

-This is exactly what you want, as the initial 6-8 goliaths will have no problems dealing with a mutalisk opening. Add a few turrets to protect your mineral lines, add your factories, and go for the push.

If he continues to make mutalisk...
-This is when you add science vessels and irradiate, which will kill mutalisks no problem. Continue making goliaths, maybe tanks every once in a while in the case you need to bust sunken lines.

If he opens lurker tech...
-Save scans because mech is fairly easy versus lurker openings. Also opt for earlier starport and vessel for detection.
