Since I see we have some Starcraft 2 fans in here, I thought I would share my knowledge of opening builds with the Protoss race.

Tech Build
9 - pylon
10 - gate
15 - gas
cybernetics core - as soon as gate is finished

Standard Build (One gate - to two /w Robotics Facility)
9 - pylon
13 - gate
15 - gas
16 - pylon
cybernetics core - as soon as gate is finished

Rush maps (use for small maps only)
I wouldn't recommend using this build against Terran since all Terran block their bases off (unless they're new)
9 - pylon
10 - gate
11 - gate
zealots as soon as gates are finished
14 - pylon
16 - forge

There are some benefits and drawbacks to these build orders.

Firstly, if you are teching, that means you are going to not have as many probes on minerals as you would if you did the standard build. The tech build is good for a mid game tech rush but leaves you vulnerable in the early game to all-in strategies.

Secondly, if you are doing a standard one gate, which is the most common build order, because it sets you up for a good defense early game as well as a strong late and mid game. However, it CAN be weak against the rush build on small maps if you don't block quick enough or aren't building units fast enough.

Finally, the rush build is very good for early game pushes. This is an all in strategy, so if your first push fails, you will most likely lose. This is because your opponents economy will be much stronger than  yours in all the stages of the game, since you spent most of your resources getting an army for an early push.

Well that's all for now. I'll be going over other things in my next edition. Until then, keep macroin', nah mean.
