Whenever I play Starcraft 2, I have made the 7 Roach Opener/Expand/Lair build order a habit. The only time a build like this succeeds in ZvZ is if my opponent either expanded early or if my opponent has even worse micro than me. I need to work on a different build order that would at the very least ensure me a 50-50 probability of success should I execute them. Been doing a bit of research and so far, the best has been the 15 hatchery build though with the 6 Pool.
Or I can stick with the build I have already learned and make some tweaks to ensure a decent ZvZ matchup. Maybe I should focus on making 5 Roaches and be a bit defensive. I could always make a counter-attack with the Nydus Network as I have found that structure to be insanely useful in ZvZ or when I am playing in Scrap Station.
If you guys are doing the Roach Opener, what tactics do you use in ZvZ?
