This build is the ultimate anti-roach build.
Make probes up to 9/10, start pylon.
At 15 start nexus, then forge then gateway and gas and pylon.
@100% forge start photon cannon at the wall at your natural.
@100% gateway start cybernetics core and zealot.
@100% cybernetics core start 2 robotics and take 2 more gases and start warpgate research and start non-stop zealot production.
@100% robotics start constant immortal production and add 2 more gateways and take your fourth gas.
@100% gateways make 3 to 6 sentries (cut immortals if you have to) then continue the normal zealot production
@9:30 push out with 15 to 18 zealots, 3 to 6 sentries and 6 to 8 immortals and start proxy pylon
Note that in order to have a huge immortal production you skip the +1 upgrades from the forge !!!!
This is the BEST build versus roach play (and speedling too considering the amount of sentries and zealots you have. It is a very very strong timing push/semi-allin but u can easily die to a fast muta play (that can happen if the zerg scouts that u have 2 robos and only 3 gateways)
During the fight keep making immortals, you must stay at a high sentry count (6 to 8) so dont be afraid to warp them, if you see that zealots are starting to die warp some more, consider adding 2 more gateways if u have the money, otherwise warp stalkers . if you can afford it start +1 attack and third base, when you see that you did enough damage stop immortal production, and go for colossus tech ideally (since you have 2 robos and only 3 to 5 gateways).
