Zerg guide

       when playing Zerg i like to scout with overlord to the nearest spot, if its a map like lost temple then i would scout with drone to another location if the overlord doesn't reveal player on first scout.  Once you find the player you decide by his build on what you are going to do, bassically in every situation I like to 14drone then pool because i can fast expand off that with roach den in ZvP or ZvT fairly easily.  

          Although if the players defenses look weak then you could most likely do a considerable amount of damage with roaches , or even possibly win the game.  Its important to normally tech lair after your safe with roaches even if you have expo to get hydralisk den, and once hydralisk den is complete you need to pump nothing but hydras and reup your economy with many drones. pump many hyrdas and continue to macro, in ZvT early infestors after expansion is good because you can fungal growth the marine / marauder forces.

            Also in ZvZ fungal growth can be useful as well vs roach / hydra, and also even stopping broodlords in they're tracks.  After 3 bases in ZvT its smart to rush ultralisks vs mass infantry forces, because they do splash and can wipe out infantry very fast.  infestors are useful to use vs terran's thors or protoss colossus, but infestors mainly for fungal growth in my opinion.  On some maps like Desert Oasis you can use fast mutalisk build and catch your opponent off gaurd in almost every matchup.  

               On the map kulas ravine, 2hat mass zerglings with speed is viable because you can catch your opponent off gaurd when hes in the process of going for an early attack.  Mainly as zerg I just do macro play like mass roach into mass hydra, zergling into baneling , muta ling with Fast expansion, different builds and ill explain more in depth with later guides this was just touching up on some basics.
