it's effective it PvT and PvZ because they never expect it maybe? the no ramp thing applies to terran defending just as much as P i thought?
seems to work for me the few times i've tried it vs randoms when i spawn P on that map...
A good four gate requires a very specific and VERY readable opener. The random players you're playing that are losing to it are fairly bad or really trying to get their meta-game on and failing miserably.
I really really hate using the "pros" as a reason to or to not do something, but there's a very good reason you haven't seen any pro-level protoss 1-gas 4gating zerg or terran (with the exclusion of if they've gone 15cc or something) in the last 6+ months... almost all gateway-heavy timing attacks off 1-base nowadays revolve around trying to deceive your opponent into thinking you're expanding via either nexus canceling or positioning your units such that they cant re-scout the nat after their worker scout.
