Reactor (2) on Factory > Build Barracks (2) on Reactor (1) > Switch Barracks (3) to Reactor (2)
@100% Reactor (2) - Tech Lab (2) on Factory > Siege Tanks
Next 75 Mineral - Refinery (2)
@100% Siege Tank (3) - Move out

at 8:00: have a large number of unupgraded marines, 2 tanks with siege mode, 1 tank 80-90% complete, 2 CC's, 2 gases, saturated main, saturating natural (~10-12scv at nat when i push).

ideal outcomes in order:
kill greedy zerg - most common below Diamond.
punish greedy zerg, use advantage to win - aim for this.
damage or trade evenly with normal zerg - must transition into third cc->ebays->gases->160 food push? if there is a follow-up 2 base timing that is good, please share
defend allins/low eco zerg with siege, counter and win - common on NA ladder


how to get there:
reactor hellion
CC
swap with rax
rax builds TL
fac builds 4 hellions
start 2nd rax as first pair of hellions are building->reactor
reactor fac swaps with TL rax
start tanks + 4 marine production
get siege with 100 spare gas while constantly making tanks
push at 2 tanks, 3rd almost out

you go reactor hellion before expand, the oldschool/'inferior' variant (as compared to FE->reactor hellion) -- gas on 13, fac, reactor after 1 or 2 marines, take gas off for cc while fac+reactor are building and you have 25 gas.

swap and make a techlab on barracks. in addition to making the swap for tanks faster, this could trick the zerg into thinking a delayed hellion+stim timing is incoming, or a marauder+hellion is incoming. you add a 2nd rax when you can, depending on your cc timing, as your 1st pair of hellions are building i believe (or around that time). add reactor to 2nd rax as soon as its done.

make 4 hellions, scout/try to deny creep/keep them alive. probably the most important thing to use these for is to scout an allin. set up depot wall in front of natural either way, bunker behind depots if u sniff an allin.

after the 2nd pair of hellions leave the fac, lift and swap with TL rax. 2nd rax's reactor should be finishing up. pump 4 unupgraded marines + 1 tank per production cycle, DO NOT GET SUPPLY BLOCKED OR YOU LOSE get siege when you have 100 spare gas (between 2-3 tanks).

move out at 3 tanks, i played vs ai, i move out around 8:00 with 2 tanks and several unupgraded marines (70-80ish supply total), and a 3rd tank shortly following. as i get or find ladder reps ill post.

if he has done an allin, or has otherwise droned lightly, do not push, either defend and counter, or transition into 3 base play with cc->ebays->gases
