I have crawled up to Diamond before I had switched to Zerg, basically because I used to play Protoss in Broodwar and I will always remain a Protoss warrior in my heart I'm afraid. Anyway, I've figured out a decent build which gives you decent possibilities for both offense and defense. Let's have a look, shall we?
Basic Numbers
Use no more than 2 Chrono boosts on Probes, save the rest for Warp Gate.
-
8 Pylon & scout right away
- 12 Gate
- 13 Gas
- 15 Pylon
- 16 Core (no Zealot, Stalker first)
- Add two more Gates & 1 Zealot
- Build two more Stalkers manually before Warp is done
- Build Robo either before or after the warp, depends on scouting and your cash levels
These are the basics which remain the same for all variations. It strongly depends whether you're able to investigate your opponent's base, because his build will determine your further course of action. You can scout several basic things, such as:
- fast Marauder push
- quick Factory
- fast expansion
- Banshee
What Can We Do?
The good news is 3 Gate Robo can cause serious trouble to all of these builds. As you charge in with 7 units (ideally 5 Stalkers and 2 Zealots) & you're getting a Proxy Pylon ready, you will:
- crush Marauders
- seriously delay his expansion in case he's going for Hellions
- in 90% of cases overrun his expansion*
- will get through his block & kill him**
*Strongly depends on the (Shakuras Plateau isn't the best map for attacking fast expansions), but since you can build an Observer right away, you can still be a great pain in the ass.
**Even if he manages to research Cloak, you can again get a quick Observer and rape him nevertheless.
This build is also very safe against some strange 1 Rine 2 Marauders attacks or even the infamous Marine / SCV rush. The latter is much more troubling and you need to scout it in time, but since you've got enough Boosts, you can use them on Gateways rather than on the Warp.
Attack Wisely
However, I'm not telling you to go nuts, warp in countless units and let them perish in vain. It is all about good judgement and game experience – if it's obvious you won't brake his lines, feel free to stick to the initial 7 units only and throw down a Nexus (perhaps even two pieces) instead.
Should that be the case, you can poke around until Terran gets either Tanks or Concusive Shells. When that happens, fall back, leave Observer behind and focus on macro. You can always add Blink later to become a pain in the ass again, but too heavy losses might and most probably will result in an inevitable "roflstomp".
Last but not the least, if you end up doing the more economical version of this build, make sure to warp in enough Sentries (usually 2-3) to block his choke before you decide to retreat – just in case a huge stimmed armada wanted to run down and quickly end the game.
Conclusion
3 Gate Robo has proven to be the safest opening with the highest winning rate I had in PvT. Although it might take a while before you get the critical judgements & resource distribution right, it will make you immune to most early pressures and even if you won't break down enemy's FE, you still stand a decent chance of winning.

All Protoss units are protected by shields, you'll see it as the little blue bar above the green if you have unit health being displayed. Once the shields get taken out, they will start taking permanent damage. If you back out of combat before your unit dies, it will quickly regain it's shield and be ready for battle once again.
