dogsi, i love you, but this is one of the more ridiculous things ive ever read.
Works for me as often as not. The key is to slow the 4 gate til my colossus is out. What I do depends a lot on what my opponent does. A common 4 gate is 1 stalker, 1 zealot, 1 probe sent to my base and they try to build a pylon at my ramp. So I have 2 zealots "fight" their units while 2 more zealots and a stalker take out the pylon before they can warp anything in.
This isn't "reliable" as they can just build the pylon farther away or there's a chance I don't spot it in time. However, it does work. When that fails, warp in a sentry or two to buy time and try to pick off units when/if I can.
I hate 4 gating. I have not tried it even once in PvP and I'm not about to start. I did it a few times vs zerg but it just felt so lame.
