Vitensby Adaptation of Sauron Zerg for Starcraft 2:
1) Overexpand everywhere and use speed zerglings, banelings, to contain your enemy. Focus on gas first and use spore and spine crawlers to buy time for units to arrive when you are harassed.
2) Drop a half dozen hatcheries in your main or anywhere you want your Spawning Grounds to be.
3) This is strong because you will avoid having your reinforcements killed when re-maxing an army under Protoss Death Ball or Marine, Tank, Thor Siege pressure.
4) If you can contain the enemy properly, as is suppose to happen, at late game you can endlessly remax and flood the enemy with the true power of the Swarm.
5) Use burrowed baneling mines instead of lurkers.
6) Unit composition: Speed Zergling Baneling Hydralisk Ultralisk Broodlord
