Source: How does T or P counter 1hatch queen?
You can thank ArcherofAiur for that postThere is also an article here which states a few of my thoughts:Hi Karune!
Teamliquid recently release a article that claims that 1 hatch queen is almost impossible to beat do to the economic advantage and denying scouting.
We were curious how Terran or Protoss should deal with a zerg 1hatch queen build.
Additionally, the 1hatch queen build is strong, but relatively easy to stop if you know this is a potential strategy on the field.
These are just a few strategies I use and by no means the only strategies I've seen used:
With Terran, you will naturally want to block your choke point. This in itself will easily stop fast Zerglings, as you can use Marines to fire upon enemies from a cliff (since they don't have LoS, just make sure you keep those pesky Overlords at bay, which is relatively easy as well). SCVs do an excellent job of repairing much faster than Zerglings can do damage at this early of a stage. Hydralisks on the other hand pose a bit more problems, but can still be handled by a group of Marines behind supply depots or even a bunker if it is needed. Terran choke points are quite difficult to break at the moment and while your enemy expends resources determined to break it, I would hope you would be teching either to Banshees or Reapers for harassment, then putting them into the defensive and taking you into the mid-game, where arguably at the moment Zerg is forced to be at a defensive if they did do the 1hatch queen strategy (key point being the 1 hatch or late expand).
With Protoss, the proposed Zerg strategy is a bit more viable and it takes a little more skill to defend against it. For me, I often block my choke point with 2 gateways or 1 gateway/1 cybernetics core (if I am teching), leaving one cell open for an easy single Zealot block. Breaking that choke point for a single Zergling hitting that Zealot at a time, is an easy block, and quite cost effective for the Protoss player. For a determined Zerg player, they would either start attacking the gateways or tech to Banelings to take out the Zealot(s).
Timing-wise, you will be able to get your second Zealot out in time well before the Gateway is even at half health, which is usually enough to push off those initial Zerglings. When your Cybernetics Core is up, this opens up Nullifiers, which is a must used unit in my opinion against Zerg. At this time if the Zerg player has converted to Hydralisks (or even straight teched to Hydralisks), you should have at least one Nullifier up, which are excellent at both killing Hydralisks (with even 1 Zealot tanking) or even better, cutting a Zerg force in half while they push up the ramp, easily allowing your Zealot to hold the choke while your ranged units like Nullifiers and Stalkers annihilate half the force with ease, putting the Zerg on the defensive now, and opening up mid-game options.
Of course both strategies require micro, which is intentional - with an Overlord scouting and giving LoS, Hydralisks can be very potent. The 1 hatch queen strategy is quite capable, but not overpowering.
Hope this was useful - though you can expect lots of things to still change and be changed throughout beta.
Zerg's were mentioned as the 'weaker' race in a developer interview not because of their early game, but their mid game. In current builds, it is much more balanced with recent changes to make Zerg a bit more threatening in mid-game, such as Roaches moving while burrowed as one example.
