First and foremost, Id like to say I dont play much PvP, and enjoy mostly micro maps, (64x64)

-Send 4 drones to mine
-Build 1 drone
-Save to 150 minerals, then build pool
-Build 2 drones while pool is generating (1st drone goes to min, 2ed -to a creep colony)
-While colony is spawning, build 1 drone

*Note* Colony and Pool pop at same time
Send drone to mine and turn colony into a Sunken
-Build 1 drone

*Note* What is next is a continuous patern "For making progress"
1 colony, 1 drone, sunken, 1 drone, 1 colony, 1 drone, sunken
Alternate every other drone goes to minerals, then to a Creep Colony.

*Note* Build Overlord when you have a 8/9 command

-Once you have 13 drones mining minerals, add another Hatchery or expand elsewhere. Extractor DIRECTLY AFTER expanding.
*Note* Expansion may occur between 12-14 drones on minerals, and it makes a huge difference in your game when you do it. Once you use this patern, you will see what I mean.

-From here, you have sunkens for defense against rush, you've expanded and gotten extractor up, time to decide what units to use, your already set for Lings, put up a Cavern and get your Hydras, or go Spire and get Mutas.

*Note on Defense* Against computers, especially on micro maps, I find that Evolution chambers infront of your Sunkens works extreamly well. Biggest thing to not neglect is air defense. This will get you EVERY time.

*Note on PvP Games* I know this can be adapted to player vs player, however, I cant get the hang of other people, but I have been known to take 6 comps (plus expansion that my partner died in) by my self)

-Finally, yes this takes ALOT of fancy finger work, but if your fast on your hot keys, and remember to alternate the drones mentioned in continous patern, its very easy. Hope this helps!

CreepColony's Opinion: I think almost any strategy works against comps, since they are so stupid. But follow all the tips here.
