I’ve been working hard on getting the new full 3 race build order optimizer over to OS X. It will be there soon, but meanwhile I just need to say how big of a pain it is to get programs ported over to or running on a new platform. Pfft.
I’ll have a link to it available here soon once I’ve fixed a few more issues and had a bit more discussion with the lead developer.
10 Extractor Trick 11 Overlord 11 Spawning Pool 16 Queen 18 Hatchery 18 Overlord
Best Zerg build that exists, period. Modify as necessary to deal with scouted info. You can do 2 sets of lings instead of drones 14/15 or double extractor for 2 sets of lings at 18. No trouble with 2 rax, no trouble with blocked hatches. If you get away with not making those lings, you’re on an excellent economic roll.
If you want to always make those early lings, then this build is better, though inferior to the 11/18 build if you don’t make lings.
10 Overlord 10 Extractor Trick 13 Spawning Pool 15 Hatchery 14 Zergling 15 Zergling 16 Queen 18 Overlord
Those 4 zerglings cost you almost 30 seconds before you hit saturation AND you are late on your second queen. Regardless of this, it’s still the most economic AND safe build you can do.
