Normally i play with Zerg for the entire game but you need to be faster.
This strategy is focusing on Zerg unit only where you need to upgrade Melee Attacks and Ground Carapace at Evolution Chamber
and Metabolic Boost and Adrenal Glands at Spawning Pool.
1. start with 15 drones
2. build spawning pool, by this time u already have 2 overlord
3. build extractor and ready to spawn Queen
4. by this time, u can spawn 10 zerg
5. upgrade Melee Attacks and Ground Carapace at Evolution chamber and dont forget the speed upgrade for zerg at spawning pool.
6. upgrade Hatchery to Hive. This way you can upgrade to Level 2 of Melee Attacks and Ground Carapace
7. if you have enough mineral, build another hatchery. The key is you need to have masive mineral to spawn a lot of zerg and control the economy map.
8. Now you are ready for first attack.
9. Make your army divided by 2 group. 1 for counter the enemy and the other one fr back up.
10. I will sacrifice my first group to counter the enemy unit and the other I will send to their base unit and attack the SCV to slowdonw their economy.
11. Before that make sure you already upgrade Adrenal Glands at spawning pool which increase their attack by 20%
12. Now you are ready for combat!
15 pool is a big risk to take, u will have very less unit when people rush u with first production. Only do this when you are confident they wont rush u, teching or big map (far from each others).
For zergling u always need to split up, speed is vital.. split up and cover up enemy and attack. when you are outnumbered, run and get covered.
pure zergling can be very risky, because mostly likely you will have excess vespene gas, i would say making mutalisk out of the extra gas will help your harassment even better.
I am having problem to fight terran, when they block i usually go air, but after they get static def I start to get lost how to attack.
