Ok ZERG VS ZERG my dreaded match up -.- ( REALLY HATE IT )
there are 2 ways u can start this off......first one is
9 Drones.....use the cancel trick then an overlord 10/9......build 2 more drones 12/17......get an extracter then a spawning pool....when extracter comes out get 3 drones there quickly then build another hatchery 11/17 get 3 more drones 14/17....
once you got the resources upgrade the hatchery into a lair ASAP I MEAN ASAP....u can pump lings out if u see zerg opponent pumpin em but not too much tho enough to kill all his lings.....17/17 LORD!.....by 17/17 supply ur lord is about to come out as well as the LAIR, after that comes out get a SPIRE immediatley......here u go this is where u choose ur destiny get lings and 1 spore colony....bring all ya lords to the spore....
once the spire comes out i mostly get scourges to get their lords and then pump out lings and mutalisk....
The other strat is 9 drones....cancel trick.....overlord......2 drones 12/17.....then a hatchery.....drone 12/17 then a spawn.....drone 12/17 then extracter.....
both are great strats but i think the 2nd strat is better but if ur caught doin this u can die or lose a lot of drones...but if successful which is most of the time in ZvZ unless he 9 or 12 pools, you can get more drones out quicker and more lings out....than the 1st strat...
