I remember in the original SC, one strategy (not sure how popular or effective it was but I know it existed) was to have a Drone go Extractor when you hit max supply before making your second Overlord, then make another Drone and cancel the Extractor, thereby giving you an extra Drone before the second Ovie.
I'm looking for opinions from more experienced players - what is the state of this idea in SC2, with the different collection rates and two geysers per base? Just curious is all.
