first get many many gatherers. then 12 gateways. start makeing zelots in all of them. upgrade there speed. then get a shuttle. get 2 probe. put one on each side of the base on the canyon. then when there front defence is taken out send all your zelots. u should have almost 75 or so. they will go in and take out alot of stuff. if u have timed it right u can have all 75 and there base surrounded in cannons in 6 min after lots of practice. this will work well all they will have left is air units. then run the zelots by the cliff and when they chase they are killed. make sure u upgrade. if u do it right then all rases except terran who will liftoff will loose all buildings before ur zelots are killed and if they are then u will have another 36 zelots before the last one were killed then all u do is bring in a few dragoons to take out the liftoffed buildings. timeing is everything so make sure u have practice before u try this in a ladder or important game but i have beat some people that were 47wins and 0 loses with this.

CreepColony's Opinion: Be sure to look out for splash damage units (lurkers, firebats, reavers, etc) because they will own your zealots.
