Problems:
After initial scouting, I can't see what he does until I get to observers.
Going light on army to tech leaves me very vulnerable to him waltzing in with his zerglings.
He can fend off any rushes or early attacks with the two colonies.
I tried several strategies against him that I've never tried before. I went early phoenixes twice. It worked the first time and I won, but by the second time he was well-defended enough to still out-army me.
When I went early DTs, he once zergling'd me and the other time scouted the tech.
When I went for zealot rushes, he was able to fight them off by having a colony among his workers, having his queen, and having the ability to create ten zerglings at once. Pretty pointless.
Whatever I went, he used mutas to harass my economy, forcing me to spend thousands on defending it with cannons (first time I've seen his use mutas ).
Basically, I can't scout him until I have observers to see specifically what he's massing, but going tech to observers may leave me already screwed over because it limits my anti-air capabilities. He can create larger armies than me when needed (being on the offensive, he generally has more resources, and Z in general is just better at macro possibilities), and my only real counter to the numerical disadvantage, colossi, is targeted by mutas and die very easily.
It's just... egh. I think I can do better than that, but since IP got to make a thread asking for help, here's my turn. I need epic ways to counter him. And, yes, I know how to play P, I know the typical counters, etc.
None.
