This strategy is fun to use against Zerg opponents. It was sent in by Skooshy22, thanks!

this might sound long but it goes preety fast.send your probes mining at start and make a good amount of probes as soon as possible.get 4 pylongs spread around your base, 2 at the front.get a forge and about 6 photons spread around your base to start.build up on the tech tree until you can get stargates.get 3 stargates and some more workers.you need a lot of gas so use all the geysers you can get to.as soon as your stargates warp in get 2 corasairs at each stargate and make some more probes for mining.get as many corsairs as you can and if you'd like get another stargate and a few more pylons.if you have done this fast enough, scout around with a nice fast corsair. as soon as you find an enemy with any air at all send the 15-20 corsairs you have and aim straight a target.this trick works best against zerg because if you kill their overlords the game is over for them.
