best thing to do vs Stargate openings - if you scout it early - go DTs.. if you scout it late.. blink stalkers and match their expansions if you can scout it. then just macro like a boss denying their pheonix's any use by not letting them pick off probes - you should then be a bit ahead - cause you haven't invested in stargates and pheonix.. so prep for a 2 base timing blink or chargelot/archon and go win..this is if you didn't crush them early with DTs.. but if you 3gate robo idk what you should do to transition - probably get immortal stalker 2 base push..?

Most of what you say is somewhat wrong. No, DT's are a bad option unless you have MC's timings. 3 phoenix arrive at your base before your DT shrine is done. Nothing stops opponent from blocking ramp and rushing robo + obs. I mean, I died to blind fast DT's few times, but each time I knew 100% they were coming, and just fucked up my ramp block.

If you got gate-robo-gate-gate, then best response (as mentioned above) is forge and nexus (TC with blink optional). Same true for gate-gate-gate-robo.
