Spine Crawler Rush (vs. Protoss)
A one base Spine Crawler/Lair rush for punishing the opponent's early expand, e.g. Forge FE. Once Lair is complete Overlords are able to generate creep to place Spine Crawlers within striking distance of the opponent's wall-off.
This build is essentially an all-in as the Zerg's economy does suffer due to getting a late 1st Queen, and if little or no damage is done and the Zerg went with an expansion-less opening he is miles behind the Protoss economically. You may wish to follow-up with an all-in involving any of the following: Zergling, Baneling, Roach or Hydralisk depending on if the opponent has opened Stargate or not; or continue the game as normal.
Basic Build Order
You can open with an Economic Pool First or Hatchery First, either one will work. If you open pool first, get gas immediately after making your Spawning Pool. If you open Hatchery First, get gas before making your Spawning Pool.
Since you get a very fast Lair, you will only have 1 Queen.
As soon as Lair completes, start generating creep with your Overlords and place your Spine Crawlers as soon as possible.
This build should only be used against a Forge Fast Expand opening, so make sure you scout this opening before using this build. Otherwise, you need to watch for scouting Probes and kill them before they see a fast Lair.
Since this is an all-in, there is little room for adaptation provided your Protoss opponent is able to hold without sustaining too much damage. If there is a second entrance via rocks (such as on Terminus SE), you can begin destroying it while your Spine Crawlers complete or while you're attacking. Otherwise, you are looking to end the game with your Zerglings as soon as you break the wall with your Spine Crawlers.
Since this relies on Protoss using a Forge Fast Expand opening, this works best on maps that favor such openings, however it will work on any map. The Zerg's goals with the rush can also affect good/bad map features, for instance if you simply want to attempt to snipe a Nexus, maps with wide open naturals such as Dual Sight and Xel Naga Caverns are preferable, whereas if you are backing up the rush with many Zerglings a map where a wall (and therefore the cannons it includes) is placed in a choke "ahead" of the expanding Protoss Nexus may be preferable, such as on Terminus RE.
Any map that does not favor a Forge Fast Expand opening will also not favor this build. However if Protoss still does a Forge Fast Expand opening on a map that does not favor it, you can still use this build.
