CLOAK A ZERGLING
Take your zergling, and burrow it. Move your arbiter out of cloaking range (just outside of it) and then tell it to patrol just past the zergling, when its halfway between the zergling and the starting poitn, unburrow.
JUMP MINERIALS
Get your probe right next to the minerals, start mining the minerals. Right after you have started mining, build a pylon right behind the probe. This will force the probe to roam and move around. At that time, start click on the other side of the minerals and the probe will get there.
PUSH A SCV
Make a building, then stop building, and click wher eyou want to go
PUSH A DRONE/PROBE
its almost the same thing as push a scv except you don't click on the minerals you Keep on clicking ahead then he gose through or you can do the trick hop a zergling then it will hop through each one.
HOP A ZERGLING
burrow a zergling then put the other one on it then it will hop the wall or whatever you want.
FLOAT A DARK TEMPALER
click on both of the dark templars then make them combine then click shift then click on one of them then hold position then click them both then click the place you want them to go then they will fly.
CRUSH A TANK
have the command center lift off and move right next to the tank, as soon as the command center starts landing, move the tank under and seige it(press o for better chance).

quickey the building that lifts off, lift it off, turn out the lights, press the quickey, and land it on the building that must be crushed.
STACKING TRICK

FLOAT A TEMPLARR
the same as float a dark templar except with templars.
FLOAT A DRONE
Surrond the drone with units, or buildings, or something. Then have the drone build a hatchery somewhere. Right after you have clicked on the place you want the hatchery to be built, press "s" to stop the drone from building it. Right when you press "s", your drone should start flying to the hatchery place.
FLY A USIT
get the ghost and USIT to attack each other at the same time then cloak the ghost then make the usit run then it will fly.
(Don't ask what a USIT is... if you know, PM me)
CLOAK A BUILDING
same thing as cloaking a zergling except you do it with a drone then when you did that build a spawning pool and the building will be cloaked.
