Basically, this strategy allows you to use dragoons as defense, and everything else. It can be extreamly useful in ally games, not quite as effective in games vs. computers.

1. After your 6th probe is done, begin a pylon.
2. While the pylon is getting built, build 5 probes, not all at the same time, but when you have the money build the probes 1 by 1.
3. After your supply is 11/17, build 2 Gateways.
4. Next, begin building zealots (one in each Gateway).
5. After 2 zealots, build 3 more probes 2 mine vespene, a pylon, and 2 more zealots.
6. Then, build another 2 zealots.
7. After that, build 3 more pylons, and 2 more Gateways.
8. Basically after this part, you mass zealots until you have at least 12, this is just about your defense, if you allies rush, use some of the zealots to help out.
9. Build a Cyorbonics Core (howerver you spell it), and begin massing dragoons.
10. Once you have 12-24 just begin attacking NOTE: After 12 dragoons make sure you build a Robotics Facility and Observeratory (observers for detection)
11. When ever you can, just expand, also keep on massing dragoons, if you happen to have a little extra cash, build some more Gateways.
12. Obviously when ever your supply reaches a whole number, build more pylons, (I like 2 build 3 at a time), also remember to build like 12 dragoons in your base before you attack (so you have some defense).
That is basically the strategy I REALLY hope you enjoy it.

CreepColony's Opinion: Ummm...12-24 goons is dragoons everywhere?
