I'm a diamond level player just looking to share my notes with the world and to discuss this strategy. I didn't really feel like going the whole 9 yards and making a guide but I feel like this could prove to be useful to other players looking to broaden their horizons.
This build is a pretty typical CC first with a fast third but the follow up is what makes this build so solid. By delaying the starport you're able to get stim and +1/+1 very quickly. The high hellion count of this build forces the zerg to invest into defenses. I took this build from his match vs life in the GSL game 2. In game 1 he favored a lower hellion count to get faster add ons. That build is much more complicated to map out but it's roughly the same.
I have also tested this build out many times in game to assure that these are the right numbers.
15 Barracks (only build 2 marines)
18 OC x2
22 Reactor on barracks
@100% Factory swap to reactor, barracks starts techlab (Start stim after 1 marauder)
34~ wall in natural (depots)
7:30 double engineering bays, then add 2 rax with 2 reactors immediatly
8:00 double refinery
8:45 Starport (reactor immediatly)
9:00 add 2 more Barracks add reactors immediately
12:00 add Factory (tehclab immediatly, research drilling claws)
Ideal mid game composition:marine, medivac, widow mine.
Make about 10 hellions then switch to widow mine production.
At 34 supply he spams depots so he can micro his hellions more intensively. He does this throughout the game
Will try to add replays of me doing this build sometimes soonish.
