xelnaga carvern proxy 1 gate, not an all-in build, but u must build ur pylon and cover it with ur gateway in a way that only 1/2 scv can hit the pylon at the corner, dont worry if u get scouted after u have placed ur gateway
cancel the pylon if u got scouted ure building the pylon in his corner, or if scv is following...in this situation. go 10 pylon and 10 gateway in ur base cuz u will have extra mineral, u will be slightly behind in econ, but just slightly IMO, but its worth to gamble cuz not every terran will wait at the corner with a scv just to scout proxy..most of them will scout the corner after 1st supply depot
if he sends scv attack ur gateway, pro will send 5 scvs, then, cancel it when it has almost finished, he will lose mining time, when the gateway is building, build another pylon in ur base, u can proceed to normal build order if the gateway is forced to cancel, then it kinda resets the game, and everyone will be doing their normal thing
if u have good multitasking and micro, u can pressure the terran to only make marines and bunkers (no teching for him) while u proceed to 4 gate warpgate warp in to ur 1st pylon, use ur zealot to snipe mule 1st(if any) and scv
http://www.megaupload.com/?d=DWNI602Wi built the pylon in the low ground instead in this game, if he pull scv low ground to hit pylon, build another pylon to power the gate, he will lose mining time
i dont recommend to build the pylon in the low ground cuz by the time u get up the ramp, the terran will see ur probe cuz there will be scv building a supply depot at the ramp, if u send ur probe straight when the game starts and build the pylon in his base at the corner, u can go to the corner without being realise by his scv which is supposed to build the 1st supply depot cuz he will be late
