When I play Protoss I keep my vZ matchup winrate up by doing the Bisu build: I throw down pylons and fast expand and run all over the map with air superiority and an upgrade lead. It's a safe solid build order opening that really allows you to outposition and outmicro and outmaneuver and outplay and outclass your opponents and get more ahead while you're ahead. To follow up I bust out, move out, and roll out with a big huge bold deathball timing attack, using the terrain to engage with brilliant beautiful intelligent clutch money smart forcefields to take minimal damage and clean up, clear out, and pick off high mobility units. This can deal a crippling blow and give me a commanding lead, sometimes catching greedy play off-guard and punishing it by going in for the kill, streaming in units, sealing the deal, and ending the game right there.
When I play TvZ I play a heavy macro-oriented calm passive steady methodical straight-up style with tons of orbitals with mules and nukes raining down all over the map. I build lots of thors, a real mech fantasy of an uber unit, so much so that I get nerd chills just thinking about it, Tasteless. It's a real blunder to move out with thors against zerglings so I hard counter the thor's soft counter by target-firing with overpowered mineral-only hellions. Against protoss I overmake vikings and use high-dps marines and infinite-kiting marauders and use drops and sick concaves and stutter step to mow down high-survivability meat-shield zealots ultra-cost-effectively with a crucial critical mid-late-game tech switch transition to ghosts.
These army compositions are really powerful and formidable forces to be reckoned with, and once they get going, your opponent is in trouble, you're going to start owning, pwning and slaughtering, and you can expect gg well-played any second.
