Goons can fit through the left of the wall and 1 Zealot can block against Zerglings. Nice. An alternate wall for this spawn can be found in this video:
I prefer the second one. 3 gap wall is scary.
Again the Zealot on the right blocks against Zerglings, but a Dragoon can move in and out of the base.
The pylon on top of the Gateway isn't needed to make it, but it is required to add Cannons on left/top side of Gateway.
Could not find anything better for this spawn. It's not bad, but it requires the Core.
The Gateway needs to be exactly there and not one lower to be tight.
Pylon is tight even without that cannon to the right of it. DO NOT use the liquipedia wall since it leaks to the left of the pylon.
This is an ideal wall. One gap wall that Dragoons can fit through. Might be unique.
Forge a bit exposed to Hydralisk here.
Pylon placement is key here.
I'd like to thank Scuzzy and TossRandir for helping me with this.
Don't die to mass ling. GL
