12 Pool into Roach Wall-Off (ZvX Economic)
Description
Nothing new here, just built for personal use practicing timings with Overwolf.
It is a beginner's build aimed to be an efficient follow-up to economic damage from a 12 pool expand. Can be used defensively if opponent counters quickly, or as a roach timing attack around the 6 minutes mark with around 15-18 roaches with speed and +1 attack.
EDIT: For the sole purpose of achieving the strongest possible timing with roaches, take and saturate only one of the natural gases. The gas ramps up too high for no reason. This results in 2-3 more roaches to push with at around 6 minutes. It also speeds up the third expansion, which helps the macro transition if the timing fails.
Video is an example against AI and is in no way perfect, nor accurate given how stupid the AI is but is an example of the steps that lead to the push. Injects are missed here and there and larva sits sometimes when it could be used. Absolutely not a reference from the macro perspective, but just a general idea.

Analysis
The goal of the timing is to attack really early with 12 lings, doing as much economic damage as possible by either killing workers or denying an expand.
In ZvZ if facing a 12 pool, turn back and transition immediately as your opponent will have defender's advantage and will most likely win the engagement and overwhelm you with a counter if he goes all-in. In such cases, consider defensive banes and/or spines, because you probably will not have time to wall off before the counter happens unless you sacrifice too much on your economy to build the wall.
