Protoss vs Protoss
Builds and what they're weak against:
Opening - Gate Zeal Core < Gate Core
Robo 3 Gate < 1 gate robo 2 gate ob reaver / 1 gate nexus 3 gate
21 "Two" (rangeless 2nd gateway at 21/25) < fast DT
1 gate nexus 3 gate < Fast DT, Shuttle Reaver
Fast DT < Robo 3 Gate 2 ob, against everything else its ok.
1 gate robo 2 gate shuttle reaver < Fast DT, Shuttle Ob Reaver
1 gate robo 2 gate shuttle ob reaver < Safest.
1 gate robo 2 gate ob reaver < THE build to do these days.
(no shuttle but can defend, get a nexus). Can defend against Robo 3 Gate
If you expand, you can die to 3 gate
(if you dont expand, then you can hold at the ramp)
1 gate 4 dragoon ob reaver < If you don't expect shuttle reaver, best build
1 gate robo 2 gate 2 obs reaver < really rich build. weak against aggressive builds (shuttle reaver, 3 gate)
Speed Shuttle: If your micro is good (confident), use it. behind/loses against: 1 gate nexus 3 gate, fast DT
3 gate: Bad on maps with ramp (at lower levels, good at contain) Gets countered by really fast DT. If your opponent tries to do 1 gate robo 2 gate ob reavers, go kill his expansion
In terms of video, I did talk about it during my stream, VOD link here:
However, since I was not prepared I might have said few things that weren't necessarily correct on the explanations. Apologies in advance, and please do correct me if I'm wrong on any of the points.
