The answer to this in early game is generally the standard 3-4 queen opening, a large number of Zerglings, and maybe a few Banelings or Roaches, if you'd like. Banelings and Roaches are usually not necessary with good Zergling and Overlord control.
When scouting, you're looking for an early gas- one started before the natural CC. If you see this, you can ...
You can't add queens to the group while they are in production.
To make things even worse you can't even set the rally point for them,since queens always spawn directly near the hatchery(in free space) ignoring the rally point.
And since they emerge directly from it,there are no eggs to be grouped.
There already are few threads on blizzard forum where ...
According to Resources - Liquipedia a drone gathers 55-60 minerals per minute. Let's take the average of that and say it is 57.5. This equals to ~ 0,96 minerals per second.
One worker on one mineral field gathers 55-60 minerals per minute
(80-85 for gold minerals), depending on distance.
As you said the cost to delete an extractor is 6 minerals (~25% ...
I believe there is no simple answer to this question. It is not about build orders or when you get the Vespene gas. Of course gas is important for zerg air, however, you can't talk about a timed zerg army as you can do it with terran or protoss. Zerg air army is so fregile and lack of DPS, therefore you can only make it by transitioning.
We should discuss ...

Most people that lair at the nat in ZvP and ZvT do it because it's easier to defend and less likely to be dropped, which is also why many people don't throw all their tech buildings in the main either. Side benefits are that it also punishes a terran that scans the main instead of the natural.
Not sure what roach timing you're referring to.
There are many possible timings, on one base, two bases, three-base roach max, etc.
Also, you haven't specified if you're opening gateway first or forge FE.
Given that the metagame right now is for gateway openings, you should scout on 9 or 13. If you see he's on a single base you drop 2 extra gateways and ...
You essentially have a different account on different servers. So when you log in there, you'll be asked to create a username for the first time, and you will have no games played. You'll play the 5 placement matches to determine your league when you start.
So there is no MMR transfer between regions, otherwise (logically) you wouldn't need to play 5 ...
Every situation is different so it's hard to generalize, but here's some considerations.
The most important problem with disruptors is that they can't move while shooting and their shot gets canceled if interrupted. In a stalemate situation it would be extremely easy to then abduct the disruptor with a viper.
Secondly, tempests have more range than spores ...
