I Can Say I'm a Pro without Bragging, because I've been playing Starcraft dince it came out about 8 or 9 Years Ago, so if you wnat to win, read this...

yeah yeah, tons of canons and pylons work out great, and so do thousands of one kind of unit. but if you really want to win quickly, and not have to spend a ton of money, then do this. after building a few pylons and canons, put gateways very close by, and set a rally point just infront of your canons. units are better to lose than buildings. then, while the enemy attacks your units, both your units and canons attack them. replace any lost units and buuildings as needed, and build a few more units. in the mean time, you should get about 12-15 probes gathering minerals, and have about two assimilators, with men making an endless chain, so when one comes out, one goes in. then, get the neccessary buildings for a high- templar, and dark- templar. research psionic storm, and ground units sheild, armor, and attack. make sure to get that side defence, otherwise, the enemy can go straight in with air, and kill all your stupid probes, and your nexus, and then you're skrewed. then, all you need is a coiple of dragoons (probably 12-16), some zealots (20-26), some dark- templar (probably 8-14) and some high- templar (6-8) (you can make some archons if you want), and that's about it. get them all upgraded, and send them in. use the high- templar's psionic storm to kill the big groups of units. incase the irst attack force dies, start making some more. you can add in some observers to scan out those cloaked units, but with how strong they are, its probably not necessary. i wouldn't bother with those pesky arbiters, because they'll just lock them down, or kill them real quick, and it doesn't help. and recalling isn't so great, because sending them in by foot, then you can kill any attck force they might send on you that's already on its way.
