Protoss - 4 Gate

The Protoss 4 gate is a widely used build, the reason it's called a 4 gate is because you throw down 4 gateways. This is a simple build to do and is effective against all races, it is even possible to 4 gate your way to diamond.

The build basically goes like this:
1. A pylon on 9 (send the probe that builds the pylon to scout)
2. After the pylon is complete you need to build 2 more probes and chrono boost them out
3. While the 2 probes are building, halt anymore probe production until you have 150 minerals and then build a gateway.
4. The second you have 50 minerals build a probe and chrono boost it out, while the probe is chrono boosting out build another probe and halt production.
5. The second you get 75 minerals (you should be on 14 supply at this point) build a assimilator.
6. Build another probe.
7. While the probe is building you have to build a pylon
8. Then build another probe while the other probe is still building.
9. Move 3 probes on to the assimilator
10. Halt probe production on 16 and build a cybernetics core the second the gateway finishes (you should just have 150 minerals at this point)
11. Build another probe
12. The second you get 100 minerals build a zealot
13. Finish building probes until you have 20 of them, however don't build over 2 at a time.
14. The second the cybernetics core finishes the zealot should also finish, research warp gate technology and  build a stalker.
15. With all of the extra chrono boosts just chrono boost the cybernetics core and the stalker.
16. Keep chrono boosting the cybernetics until completion
17. Wait until you have 450 minerals then throw down the 3 gateways at once.
18. Move out of your base with your stalker and zealot and also bring a probe (to throw down your proxy pylon).
19. The second you get 125 minerals build a stalker (this stalker will also go to the middle of the map with the stalker zealot and probe)
20. Advance basically next to your opponents base and throw down another pylon
21. The other stalker should now reinforce your army of a stalker and a zealot, the warpgate technology should also finish at this time.
22. Warp in 4 stalkers. (The warp in should be at approximately 5:40)
23. Send the 6 stalkers and 1 zealot to the opponents base.
24. Heep reinforcing your army and even chrono boost the warpgates to get out units faster.
25. Build a pylon when needed so you don't supply block yourself
26. Keep applying pressure and hopefully your opponent "GG's"


This is the fastest 4 gate build and if it fails it can be almost impossible to come back from due to lack of tech and probes, however if you deal enough pressure or in lower  leagues it can be possible.
I hope this build helps fellow Protoss players advance on though leagues.
