Most of the time people will send in a probe at start to make cannons on the side of the opponents workers but they are eazily seen.This works much better.

-make the needed amount of workers
-make light defence
-create barrack
-lift barrack and drop it in opponents base
-make marines bats and medics
-while enemy is distracted make heavy tank and golioth attack force
-take out front of base and make opponent look like a fool

Another effective use of this strategy is the nuking strategy

-make the needed amount of workers
-make heavy defence
-make barracks
-lift barrack and drop it in opponents base
-make all technology to get nueks and ghosts
-upgrade ghosts cloaking system and range
-make 2-4 nukes
-you know what to do from here

DOWNFALLS: If 2vs2 and have bad ally you will get crushed
If opponent has side defence forget it
Massive hydras or goons could kill you bad
TIP: Maybe you could use the blockin technique

CreepColony's Opinion: Since flying buildings are mad slow, I would only do this strategy if I'm right next to my opponent.
