This is a build that I used in front of a Terran:
At 3 min 50, it is very important to scout with an overlord because you'll know if Roach/Ravager push will be a good choice or if you need anti-air
The queens are made for defending Hellions and the baneling nest is made in case you scout Helbats

At 3min 50, I scouted a double factory opening (producing mines and tanks).
I reacted by launching the Lair and the Roach warren with evo chambers. I saw that my opponent didn't have so much troops and I decided to attack(he had 7 mines and 3 tanks + some marines)
With corrosive biles, I destroyed the tanks and roaches concentrated on mines and marines ( they also helped for destorying the last tank)
