As a Zerg, the Deathball really hurts.
Even on 2 base, the Deathball is pretty significant to deal lots of damage already.

Good strats are always to take put an early pylon in the zerg's natural. This delays the expansion and makes your 4 warp gate rush more powerful.

Also you can go into a canon wall-in forge fast expansion.
Just put double pylons below the zerg's ramp and a few canons behind. That is soooo ANNOYING for zerg :P

If you can put pylones there, just place 2 canons behind the mineral line, that will still harm the natural expansion plus canons are quite powerful even against roaches.

another tip is to always harrass your zerg opponent. You can go to my Harass thread for more ideas on how to harass zergies
