This build focuses on heavy macro with an early third base, heavy droning followed by mass roach till you are maxed out with a speed roach/zergling push to follow. The power of this build lies in the ability to create a maxed out army very early in the game in which you are able to continue to macro and tech up to infestor/broodlord or another composition of your choice and if you lose your army you have the ability to remax very quickly. Key timings are highlighted in red.

From here on you want to make as many drones as possible while scouting the protoss' base with overlords as well as continued zergling scouting around the map for hidden pylons. Don't be afraid to make zerglings, spines, queens or spore crawlers if you scout aggression from the protoss player.

once.

Move across the map and start to be aggressive against the protoss natural but don't overcommit because there is a huge risk of getting trapped in forcefields. From here feel free to tech up to your choice and add spine crawlers at key chokes and bases as well as reinforcing your roach zerling force in the attack.
