Starcraft – ZvP: Gateway aggro -> Phoenix -> Robo deathball: What went wrong

starcraft-2starcraft-protossstarcraft-zerg

I'm a platinum zerg having trouble dealing with protoss lategame. Previously I always did
Stephano's 12:00 roach max, which worked most of the time, but now I want to learn to play standard. So now I'm at an impasse here with the protoss deathball. I just can't beat it. I think my scouting may be an issue here – I sometimes overreact or underreact.

I sent a 10 drone scout, which saw a gateway expand, so I went 3 hatch before pool, with a 5:40 roach warren to defend timings.

When I saw multiple gateways in my opponents wall, I produced roach/ling to defend, but I think I overproduced and came out behind. How do I know how much defense is necessary to defend early-midgame gateway pressure? And if they don't attack, and just sit with there units, how do I know when I can start droning again? Or maybe in this scenario I should just keep producing units and trickle in the drones instead.

Anyways, I ended up defending my opponents gateway aggression with too many units left over, which soon became useless. I droned up my third once I dealt with the zealots. Since I saw robo units when I counterattacked, I went for an infestation pit and produced mass static defense for a transition to swarm hosts.

I've seen Catz defuse the deathball this way on his stream using swarmhost/spine/spore/viper/infestor/hydra, so I tried it too. I felt my lack of APM was a large factor in my loss. If I played faster I could have a lot more static defense ready, dealt with their harass and micro'd better against feedbacks, but this is platinum and nobody knows what they're doing.

I'm sure my opponent made a lot of strategic errors that I could have exploited, but I don't know where they are. APM will be developed the more I play, nothing I can do about that. In lieu of more APM, what strategic errors did my opponent make, and how do I recognize and exploit them?

This game was against the same player, who went for the same opening again.
Gateway expand -> zealot pressure -> phoenix -> Robo deathball.

Here I tried roach/hydra into vipers, which failed miserably. Colossus just melted everything. What could I have done better?

Please don't tell me I need to brush up on my mechanics, that's pretty obvious. We had similar APM and I'm sure my opponent made a lot of strategic errors too, I just need to know where they are. Thanks for your replies.

How do I know how much defense is necessary to defend early-midgame gateway pressure?

Typically you don't make units until you see him move out. An overlord sac will get you an idea for what he's doing (all-in vs pressure). Making sure there are no hidden pylons on your side of the map is very important, because you need the time between his base and yours to make units. Without this buffer, you're either making units blind or taking a risk, because you can't scout exactly how many units he has, and often it's difficult to scout exactly how many gateways he has.

Generally speaking you drone to about 55 on 3 bases. If he doesn't take a third you should be extremely careful droning. Most likely you can stop at 60 drones and make units until he has a third started.

Your ideal composition for dealing with the deathball is swarmhost(or roach)/hydra/viper.

You can use ling runby's and extra expansions to use up excess minerals. 2-4 overlord zergling drops in the main are extremely annoying and often very effective.

You should have a sizable supply advantage and maxed before 16 minutes, so that you can apply pressure and hopefully grab a few expensive units from him before he pushes out with 200/200. Also, denying the 4th base is paramount

Hydralisk timings ~ 11:00 when he goes phoenix are very effective
