Topic Tips on ZvZ?
hydras are so bloody good against mutas its not even funny. if you scout a spire, throw down that hydra den and a couple extra queens to spread creep everywhere.
hydra den makes so fast its not even funny, if you're scouting diligently and the opportunity arises, spew out a creep highway and push him with a small hydra roach force, he'll be really weak initially and you should easily overrun him.
Mutaling still works for me. If he gets hydras, I go for sling/bling/mutas. Roaches can be a problem but if you mass enough mutas, it should be ok.
Also, I always try to snipe the queen. If the queen goes down, he will have a hard time replacing his units.
After sniping the queen, always Contaminate the hatchery too delay him. I think Contaminate skill is incredibly usefull on Z on Z since you only have one target (which is the hatchery/lair/hive). Contaminating his hatcheries twice in a row will probably hand you the game
