I suggest a 4 gate stargate build. It's pretty common right now, but Zergs still aren't completely adjusted to it. Go FFE and take 2 gas at normal timings for Stargate. Add on 3 more gates for a total of 4 and have a proxy pylon where his third would be (he should have a third if you're highly ranked, if not he's probably doing a large push. If you are of lower league and he didn't go for a third, place it near his natural). Warp in a good amount of zealots and start harassing while the voidray is on its way. At the very least, you force him to stop making drones and deal with your attack. Best case, he was too greedy and you kill off an expansion. During this you can take a third of your own, add on a lot of gateways, or go into higher tech and go for the game winner. I suggest watching pro VODs for timings.
