just play
and watch some steams, and adept it to your own playstile/elo
I watched Neuro, a more macro player, that stays on low tech pretty long, and react to opponents
and Glazerbeam, that likes to cheese 66.6%of his games with roach/ling tech in 5min games
So i mixed that up a little for my playstile, and mix up my owns builds aswell
and most/best info, you find in here
https://liquipedia.net/starcraft2/Larva_(Legacy_of_the_Void)Hatchery spawns 1 Larva every 11 seconds
The Queen injects 3 Larva eggs which spawn after 29 seconds.
So you need to inject and spent 3larve when it spawns, and keep your larve low, within 4seconds, to make 1queen produce as many larve as a Hatchery
Queen larve best when capped at 200supply, when hatchery larve production stops, to pile up larve, to rebuild when fail (if attack before supply capped, you can spent larve meanswhile attacking)
Queen cost 175coins incl supply
Hatchery cost 350incl worker-75supply=275coins
Hatchery spams creep pretty good, you need at least 2 tummors and 2min, to make 1queen finaly reach the creep of a additional hatchery.
Ofc a queen is a combat unit, for eurly defend, but its slow as fck offcreep
3hatchery+only 1queen for creep, pretty good start economie, then tech, then 5hatch.
Thats about same larve as 4base+8queens, not that you need that many larve when build things like hydra
and you only payed 200coins extra to get 2 stronk production building instead of queens, witch allow not full execturated bases to be verry effective.
