[Estancia]

Greetings, I am a silver protoss player.
My usual play style is a protoss deathball style where I play defensive until I gather a deathball and push out for an all in.
The problem with this build is that this allows the zerg player to get ****load of bases and contain/harrass me to death.
So far my only successful offesnive play would be 4gate during PvZ (even in PvP I always go for defensive 4gate), and my only form of harrass is dt which I transition into archons later on (in ZvP again, I never harrass against other races)
This is giving me lots of problems, because this gives the opponent opportunity to expand and tech like mad while I usually play defensively on only 2-3 bases, and this is exploited extremely well in PvZ (in silver and for other races, even given the chance people usually stay on 2-3 bases ). In the end they completely overwhelm me with 200 maxed army + 8 hatch with insane number of larvae)
I need some builds that allow me to play aggressively in mid to late games, and some tips that will help me.
Thanks
