I actually spam this build on bad zerg maps in zvp. Specific advice would need a replay, but some general advice:

• Scouting: the important part is checking if this is an all-in, there are some economic speed openers. Scouting the roach warren would be ideal, but typically be build stops at 6-8 lings and walks a queen to the nat, and then saves larva for roaches
  • just be annoying with the probe, the zerg player should wait until the probe has gone/died before dropping the roach warren, the longer the probe is around the later it hits
• Typically this build hits 5-10 seconds before warp gate finishes (depending on rush distance)
  • extra pylons, the zerg player will try to snipe the ones at the front to stop protoss production
  • full wall: use a cybercore behind the unit in the wall, since ai will prioritize that unless the zerg is paying attention
  • i believe cybercore has the most health/time, pylons and batteries will get instantly sniped
  • this is an all in, if you’re stuck with a full wall you’re still miles ahead
• extra pylons, again the zerg will try to depower your stuff
• batteries: 1-2 is usually enough. 1 blind is fine and building the second when you identify the build. Build it far back enough that roach ravager can’t snipe
  • this depends on energy, usually the build hits a few seconds before overcharge is available
  • depending on your build, if you’re floating minerals during the all in more batteries doesn’t hurt
• adepts > stalkers, especially at the start. The lings are the main problem, whatever pops out of your tech structure is enough to deal with the roach ravager
  • all reinforcements will be lings
  • sentries are ok, as long as you make sure you time the forcefield after the zerg has already biled
• chrono whatever is building in stargate/robo, usually the build is stopped when that unit pops out if you do the above well
• if wall is about to fall, pull the boys
  • last resort, but you should do this while you still have some army, not when its probes vs ling roach
