The Protoss opens with zealot pressure without taking an expansion, which I hold, but his corsairs then arrive before my spire is even finished and I can't break his ramp because of the zealots and cannons. He then follows up with a robo and just reaver drops me to death.
How do I deal with this as a zerg opening with an overpool? Do I have to skip ling speed to get lair faster? Or do i have to make hydralisks to defend the overlords?
