Protoss build orders

Today i wanna summarize all of my knowledge about different Protoss strategies with according build orders they used.
Let's devide this article by matchups, so first part would state for "PvZ".
Those BOs work best on 1v1 maps like Steppes of War or Blistering Sands.

Assume Zerg goes fast expand:
build 3 probes
9th probe - raises Pylon
12 - Gate
14 - Gas
16 - Pylon
17-18 - cybernetic core
18 - Second Gas

From this stage on If we have scouted that the Zerg is going fast expansion cut probes at about 24-26 ish and do a 4-5 warpgate early timing push with lots of sentries and a even mix of zelots and stalkers. Once you do your timing push it is very significant that you respond properly to your enemy's type of army. If he spawns a lot of lings to uphold - warp in zelots. If he goes roaches to defend - warp in stalkers. Always hold a few sentries for the force field or shield ability.

Defending from rush
9 - Pylon
12 - Gate
14 - Gas

For this point you should already have scouted your opponent and if you noticed Zerg spaaned 6 or so zerglings and is rushing toward your base, you should block your choke/ramp (with boosted zealots/probes). If you allow lings to go through deep in your base it would be really hard to handle them and lots of micro would be involved.

Default PvZ build
9 - Pylon
12 - Gate
14 - Gas
16 - cybernetic core
16 - Pylon
18 - Gas

At the Gate order zealot, sentry, stalker (right the following order), from that point most of Zergs go roach or muta. Despite the fact there are two more strategies from Zerg to consider (speedlings, trying to push you or expand with lings/colonies to defend from your attack) massing stalkers with sentries will counter roach/muta attacks.
The main problem here is to scout what Zerg is going to do and to react cuz skilled Zerg will destroy your probes or zealots with lings (they have better speed even w/out upgrade).
