I've been playing SC2 for a month or two casually and have a 37/37 win loss ratio in 1v1. for some reason I can't beat Zerg with any amount of consistency. I'm probably around 60 or 70 percent for the other 2 races, but I rarely can beat Zerg.

My play style is a few different methods. Sometimes I Zealot rush, other times I tech to air or robo and other times I try for a midgame push with Stalkers, but none of them seem to work great.

I understand scouting is key, and making changes to your strategy have to happen but any time I change my initial strategy I do worse than just trying to stick it out. And it just amazes me that I consistently get beat by Zerg.

Any tips or advice would be helpful.

P.S. I'm a newbie, so I know I need to work on my mechanical skills but strategy is the bigger reason I lose to one race over another, not my lack of clicks per minute.

Begin Edit...

Great answer. Some good insight into how to play against zerg... But it basically sounds like I need to work on my micro to more efficiently handle zerg units. Which makes me wonder, do protoss/terran players tend to play games where micro is less necessary and this is why I match so well against them. The more I think about it the more I realize my strategies, require minimal scouting and a reliance on the typical play style of the race to choose my options. Terran usually turtles and I have extra time to tech or expand, protoss is often a 50/50 of rush or tech to tier 1.5 or 2 which i can either either tech or rush also and then it comes down to who is faster or better at micro, with zerg it seems I get overrun, and my micro loses me the game.

  • Btw, if you are a bit of a newb, then execution will have a much bigger effect on your win % than any strategy. If you have good execution you can probably get into diamond with just about any strategy.

So PvZ is based around a lot of different concepts and its hard to pin down a specific list of strategies you should use. Instead, let's examine the concepts and then we'll look at some of the more popular strategies and how they implement them

The Robotic Facility

The Robo Facility represents many things, but one of the most important of them is the Observer. If you are forgoing a Robotic Facility then you are making a contract: You are sacrificing the power of the Observer as a scout in exchange for something (more Gateways or Air or something else). Because of this contract, you have to make up for that deficit in scouting some how. The reason things like 3 Gate Robo into Colossus are so popular is that it leverages the Robotics Facility for both scouting and unit production

The Gateway

There is no secret that Warpgate is one of the most powerful technologies that Protoss posses. This combined with gas heavy higher tier units means that you don't really have another mineral dump. Additionally, many of Protoss' lower Tier units (like the Stalker) continue to play a vital role into late game. Strategies like 4 Gate really emphasize this aspect. Ultimately, none of the "money" units in a Protoss composition come out of the Gateway. This means that while they will makeup the bulk of your army your real power needs to lie else where. Even for strategies like 4 Gate Blink Stalkers, your power is coming from Blink, not the Stalkers.

Force Field

Against any sort of ground army Force Field is invaluable. This means some portion of your Gas expenditure needs to be on Sentries. It also means that you can't let these Sentries die. The later you get into a game the more energy they accumulate and that means the more you can abuse Force Fields. A number of Protoss strategies peak at their mid game. This is usually because they have critical mass on their money units while still having a significant number of Sentries left over from early game.


Just because you're playing against Zerg doesn't mean you shouldn't expand. In fact, more than any other match up it means you have to expand to be able to keep up in production. Since you can't throw away your army like a Zerg player can (because of their faster Hatchery based production), Protoss players have a tendency to stay on 1 Base longer than they should because they have a large enough army to defend it. This leads to poor strategies like 1 Gate into Colossus. Ultimately, if you don't expand you'll never be able to make a significant push to kill of the Zerg player and his production will eventually catch up to your standing army. At that point you've lost. Failing to expand is the slow death. Strategies like 1 Gate Expand or 3 Gate pressure into Expand are designed to take advantage of the Protoss standing army to dominate a Zerg. 1 Gate is designed for more passive Zerg players, while 3 Gate is designed for more aggressive ones. If you see an early expansion from the Zerg (around when you're getting your Cybernetics Core) then you can safely expand. If you see a more aggressive build, progress to 3 Gates and then expand.

Photon Cannons

No Race depends more on their static defense than Protoss. This isn't because Photon Cannons are amazing (quite the opposite), but rather because of the lack of a good mineral dump. As a result you can usually afford a number of Photon Cannons to help defend your expansions from light raids, and delay more heavy assaults. Remember, you don't build Photon Cannons to hold off an opponent, just to buy your army time to get there. Now, many people will be quick to point out that your other mineral dump is the Zealot; while this is true, the Zealot is one of the few units that actually gets worse as the game progresses (as compared to Marines which get better or Roaches which stay about the same). While Charge does help some it doesn't make them effective killers and they don't synergize nicely with Force Field. Instead, think of them as Meat Shields to keep things off your Colossus.

The Money Units

Protoss has two amazing units that are frequently called "Money" units: Colossus and High Templar. Against a Zerg (or even Bio Terran) feel free to use both. Of the two High Templar are really a winner because of their much higher AOE dps. However, High Templar represent an extremely high Tech investment and you will frequently see people transition from Colossus into High Templar in the late game. The reason it is so high is that High Templar need, not only Templar Archive, but also Twilight Council; even then they still need to research Psionic Storm and Kaydaren Amulet to be really effective. Compared to the Colossus which is effective even before its upgrade, its not hard to see why people transition into High Templar. At the same time a good mid-game timing push at 4-5 Colossus can bring down a large number of Zerg players.

The Lack of Air

Protoss air is surprisingly lack luster. While Phoenix are effective against Mutalisks you can't really keep up production with his numbers without over committing and leaving yourself open to a Zergling assault. Like wise, Void Ray are a very situation unit. They excel in a very limited number of cases and do poorly in general army composition.

So let's break down a couple strategies and see how it mixes these concepts together:

3 Gate pressure into Expansion

3 Gate pressure leverages the strength of Warpgate tech to prevent the Zerg from expanding unhindered as well as giving you room to expand yourself. Because you're not going Robo right away, you need to use contact with the enemy as your scouting mechanism. If you haven't had contact for a while its possible you might get overrun with something unexpected. You'll want 2-3 Sentries to fight off early Zergling play, but since you'll be Zealot heavy your main concern is keeping them alive.

Once you're on 2 base you can transition easily into 5 Gate + Robo for a more powerful mid-game. To cut down on any Zergling harassment make sure to leave a Photon Cannon or two at your natural

3 Gate Robo

Because you chose to go Robo first you should have a good view of what your opponent is doing. If you see early pressure this means you can build a bunch of Gateway units quickly. By comparison if you see a more passive Zerg you can use this to tech quickly to your money unit (the Colossus) and expand. You'll want Sentries to cut down on any harassment, but you should largely be concerned with transitioning into 2 Base and building up a decent army. A nice timing attack here is at 4 Colossus + upgrade.

4 Gate Blink Stalkers

This is a very aggressive build and you're going to rely very heavily on pressuring your opponent to keeping him off your base and keeping an eye on what he's doing. Unlike 3 Gate pressure your goal is to actually end the game in the early mid game. Some people might consider this a bit of an "All-in" build because its hard to recover if you aren't successful. Its important to understand that you're making a sacrifice in Expansions and Scouting for greater strength. If you don't have a good feel for this trade off chances are your opponent is going to punish you for it.

  • I'm surprised you think Zealots get worse with time. They're basically melee roaches, only cheaper and more health plus available earlier. Moreover, they excel versus units like siege tanks (and i guess Thors).

    @RCIX Thors, strangely, have some of the highest single target dps in the game, so they're actually really good against Zealots (as are Siege Tanks). A number of people have pointed out that Zealots have an extremely high efficiency metric (health*dps/cost), but that's balanced by the fact that they're Melee units. Any ranged unit becomes more effective as you have more of them. By comparison Melee units effectiveness is proportional to the surface area of the army. That's while Marines get better and Zealots get worse. Additionally, AOE gets better in Mid->Late Game.

  • Its worth noting that Ultralisks avoid the "surface area" problem by cleaving into units behind the first row.

  • Good stuff, I would argue that protoss air is currently underused in the metagame. I think Phoenix rays and carriers all could have potential in the future. Just need a Bisuesque pioneer.

  • @Mark so if you talk to NonY (who pioneered some of the early Phoenix play), the current Meta game just doesn't support Phoenix play. You're too dependent on Robo tech that Phoenix play sets you back too far. I think there could be a place for it in the future, but Protoss will have to be less dependent on Robo first.

There are three rules you have to follow against Zerg, otherwise no strategy will ever help you:


Never let the Zerg build lots of drones without having to build units, always try to keep some sort of aggression up or threaten to attack (you don't have to commit to an attack, just make sure he builds units to defend instead of drones).

If you go 2-gate Robo, which is a more economic build than 3-gate Robo and allows a relatively fast expand, you can get your first 1-2 observers followed by a warp prism to warp in zealots into his mineral line. Just try to save your units and don't just sacrifice them, your warp prism can transport, not just warp in.

Everything that makes the Zerg use his larva for units is good, if he can use it for drones he will quickly have an unbeatable eco where anything you do will be countered by him just having a ton more of units.

Even just moving your army to the middle of the map just to showe that you are there and have a big army works very well, the Zerg will almost always react by producing a lot of units.


You always have to know which tech options the Zerg has. If you scout the spire getting built you have enough time to go 2-gate + double stargate and counter the typical muta/ling with phoenix/zealot. If you don't scout it in time then there is no way to get enough air units to counter the masses of mutalisks he can get, which can often be an insta-loss if you don't have a lot of stalkers and sentries already. That said, stalker/colossi works ok against muta/ling if you get the chance to move out and attack immedatly, otherwise he gets to the critical number of mutalisks and just kill all your workers and then out-produces you.

If you see a roach warren and later a hydralisk den your best bet are sentry/stalker/colossi followed by a slow and smooth transition into zealot/colossi/high templar (zealots as mineral dump and wall for the templars and colossi).

It's important to know what he has, the wrong tech choice can cost you the game.

Another factor for scouting is that you have to regularly scout all possible expansions, there is nothing worse than to try to expand to the gold only to find out that the Zerg already has a fully saturated base there. As Day9 says, it's the worst feeling in the world to see an active expansion you didn't know about.

If you don't want to commit to robo tech before knowing his tech path, remember that hallucinations, especially the hallucinated phoenix, can be quite effective as scouts. The upgrade is cheaper than getting the robo and you need the sentries anyways. This way you can scout after two gates and then decide for either robo or stargate and it's usually right in time to check when he gets his lair up so you can often see what he follows up with.


Don't let him out-expand you, always try to keep up. Especially if you don't apply pressure you will fall behind very quick.

  • +1 on the last point. If unharassed, I (as a Zerg player) can expand all over the map extremely quickly. You don't want to let me do that.

It would be great to know what part of the game are you having trouble with? An early pool rush? Any specific mid game units?

Blink stalkers tear apart Mutalisks, and protect your Colossi against Corruptors. Good micromanagement of Blink stalkers backed with Colossi mid-game are really a great counter against the most common zerg armies. Immortals are great against Roach armies and try going Overlord hunting with a few Pheonix (which are also great at picking off Queens).

The general rule of thumb with Terran and Protoss against Zerg is to always keep up with their expansions. A zerg needs to have at least one extra expansion to keep up against Toss/Terran so deny them expansions. Use an observer to eradicate creep tumors to help your ground forces against their speed advantage.

Other random tips include walling off your base to prevent zerglings from seeping in (then use warp gate, air or back doors to get out), Speedlots at every expansion and lots of photon cannons at your expansion to prevent a muta harass.

I find this series particular good to watch (The "Viking Cup") as it is intermediate level players, three games, PvZ:

  • I would say my biggest weakness is a transition from ground to air. Typically if things are going good for me I'll either tech to colossus or void rays. Colossus has worked a couple of times but it seems like lately they just keep dying to quickly, I then get attacked by mutas that I cant defend against. And void rays just cant compete with mutas, the only time they work is if the opponent just isn't good and has no answer. I have tried the stalker push but to little effect, mostly because I think I need to work on my micro.
