Note this build doesn't have any info about early pools. If you prefer to play pool-first for safety go ahead, just make sure your gas is no later than 1:10 and you can still follow the same sort of build order
2 lings to scout
2:50 (50 gas) - bane nest
33 - 3rd base
34 - 44 - lings
4 banes (your preference)
Drone behind it
Eventually roach warren + 2nd gas (10 drones on natural + fully saturated main is a good marker - but be flexible)
Evo + Lair + 3rd gas not too far behind this
Or roach-bane or ravager-ling timing
Sometimes skip upgrades and go straight to mutas, only cut roaches as the spire is finishing so you still have good defence with mass unupgraded roach
Control Group Stealing makes your life a LOT easier:
Make sure you scout with 2-4 lings to see if it's gasless or they're skipping ling speed. If going all-in on lingbane might still work, but otherwise just drone super hard to about 3 gases, and 2.5 base mineral saturation then pump roaches while scouting what they're doing..
Always leave a safety bane or two at home
If they’re committing to huge ling-bane you might need to as well
If you ever get stuck in a big ling-bane war remember that the aggressor is usually the favoured player - try to keep the fight on his side of the map
If you ever swap into a defensive stance - add a queen or two and bring your queens to the front - that’s your defensive anchor (ranged dps to be efficient)
Stages of learning:
Stage 1 - ling-bane all-in. Just nonstop rally those zerglings from 33 supply and make as many banes as you can and hit relentless waves of aggression - no transition.
Stop hotkeying new lings, just rally to outside base (camera hotkey on rally pt if you can. You can still hotkey as normal if you're not a high-level player)
Stage 2 - roach timing - stop droning at 2 mineral lines, 2-gases. Hit a big all-in timing.
Stage 3- full macro build
Need to micro the banelings once they get into the mineral line
Shift click them on the drones!
Keeping banes up at all times will allow your attack to keep on going forever - any moment caught without banes you lose a lot of momentum
If you do lose all your banes try to hide lings for a counter or a surprise aggressive morph out of vision to keep up pressure
The idea here is to learn 2 very strong waves of aggression, one at a time, and only then transfer into trying to play a more "reactive" or "macro" oriented style of play
