The 1/1/1 was popularized by the Terran EG.PuMa at Dreamhack where he used this Build Order against all hi Protoss opponents. This strategy starts with a Barracks, a Factory and a Starport, one after the other. The Factory and Barracks use the Terran minerals for the Marines and Hellions while the Starport will produce Banshees or Medivacs. The Vikings will be present to counter the same strategy.
After your standard start with your Starport, one Gas will be enough to produce Banshees or Medivacs. Two if you want to do some siege research for your Tanks or Cloaking for your Banshees. The minerals will be spent on units or in a Command Center if you want to expand faster, but the standard transition will be adding two additional Barracks rather than a base.
** the numbers 10/12/16... refer to your population in the game **
***Don't stop your production of SCVs while creating your Build Order.***
• Your production of Marines can be used if you feel that your opponent cann't counter your attack based on your Marines. However wait for your first Hellions to maximize the attack damage.
• You can't produce Siege Tanks and Banshees/Medivacs with a single Gas.
• This is a Build-Order based on very fast teching which allows you to take a second base if you want to surprise your opponent.
So, do you think you can do my Build-Order as well as me?
