This build is designed to work with a 2-base chargelot all-in build, as they both hit at 5:10-5:30.
41-drone roach timings work in both ZvT and ZvZ in 1v1, but you might want to go pool first in 2v2 to help defend your ally against some rushes like 12 pool or proxy reapers.
Protoss normally walls off the natural vs zerg in 1v1, but can't in 2v2 so their natural is exposed.
Vs proxy reaper, your ling speed should finish when they have 3 reapers, so you should have speedlings in time to help defend.
In ZvZ, you wall off your natural to prevent ling floods, but you can't do that in 2v2 so you'll need to start ling speed in case. (It later gets cancelled when you start your roach warren if they're not being aggressive)
