[D] PvZ - Establishing third with Skytoss (viable?) - Page…

With 3 hatch opening, my response after scouting double stargate at around 7:30 (maybe with an unusual amount of cannons?) is basically:
-Stop any roach production, maybe only 2 or 3 preparing for potential random zealot harass. Mass roach is never a proper response for this, as you just never have a chance against a cannoned simcity of protoss, with voidrays and even a few force fields.
-12~16 speedlings (later 20+), also for zealots and more importantly denine protoss getting extremely fast 3rd
-Grab 5th and 6th gas and 4th expand, (in contrast to standard stephano style's 4 gas and macro hatch), DRONE LIKE A MAD MAN. You need good economy for late game. You will eventually need a 5th macro hatch, and keep expand like madman in mid game for gases
-Extra queens, may be 6 or 7 in total. Also at least 1 spore for each base to give you more reaction time.
-Spire, not hydras, not infestors. You need to be aggressive (while macroing hard), and hydras or infestors just sucks off creep. They also need to much time to wait until reliable (in numbers for hydras, and energy for infestors) so just no hydras or infestors, at least in early-mid game.
-Double evo chamber for melee and carapace. Lings will be your mineral dump in the mid-late game, and broodlord is the only proper siege against cannons. Also get burrow, as a single burrowed ling block for expand is just as annoying as a pylon block from protoss

Since you will need some extra upgrades and need to build lots of units when the spire is finished, you need so much gas and a double spire at the very beginning may not always be a good idea, but you will eventually need that if the protoss player is going to fully commited in skytoss

When your spire is up, make a mixed units of both mutas and corrupters. For some reason I would prefer corrupters over mutas, as mutas just sucks against phoenixes and also "not that good" against large number of voidrays, while corrupters is "not that bad" against both, you have to make mutas to force your opponent to create phoenixes or else those gases will eventually be used for voidrays or carriers that are much harder to due with, and you need corrupters to protect your mutas.

There are 2 important things to play with this kind of protoss:
-Force engage to trade voidrays, even under cannons. You just need to lower his void ray count before it is like 80 supply+
and become impossible to hold. I think that it will be an acceptable trade if you can do it in like 1.5(or even like 1.8) : 1 in supply count. It is fine, since you should (and NEEDED) to have more gases, smaller army favors you.
-Active lings runby, mainly for denining the 3rd, but also needed for protoss's upcoming expands. Unless protoss just extends their cannon wall along the way from their bases, they need to create extra ground units to defend their new bases until the new cannon and simcity is up. I don't think it is a good idea for a protoss to try cleaning swarms of lings with voidrays. Carriers do better, but anyway it may not be an ideal situation for protoss to leave their air units in open areas for trade without good cannon support. For this, zerg need a very good macro to flood zerglings, a lot of zerglings cause you will eventually have an insane amount of minerals.

If any of these fails, then it is already a GG. It is just hard to fight a protoss with 4 bases. It is even harder to fight a protoss with like 150 supply for this style. Zerg needs at least 5~7 bases to be in good position even if protoss didn't get an ultra fast 3rd and 4th, or with a super huge air army.

Late game is like spine walls defending ground transition / infestor defending air / air unit chasing anywhere / random lings swarming / broodlord sieging or whatever Lots of apm is needed though.
