The main one I do is a multi gate build good against everything I guess and helps prevent rushes, build your pylon inside your base just close enough to entrance so that your gatways can both block off the entrance leaving 1 Z in the middle of them effectively creating a wall-in from lings entering. if your playing terran and u think they may reaper rush, which they always do, go wuick for a cybernetics build and chrono a Stalker and keep him patroling your mineral field. I cant remember exactly but its effective offensive build as it allows you mass units once u ahve stable income. Keep in mind you almost continually build probes unil you have 2-3 on each mineral and 3 on each gas. 9 Probes - Build 1 pylon just before your 9th is out 1 Probe as soon as pylon is done send a probe to build 1 Gateway 4 Probes chrono boosting queue 1 or 2 at a time only 1 pylon and 1 zealot, chrono boost your zealot Contiue to build 1 Zealot and 1 prob at a time while chrono boosting your zealots. 1 Cybernetics and 1 Assimilator putting 3 on Gas as soon as done 1 or 2 more gateay while making sure to get 1 pylon every time u get 4 supply under your limit. push out with 6 or so Z at this tme to test their df, if they are closed off, go home and build your first exp, at this time u should have hit 3 probes on each mineral and have about 4 gates,
The most important thing to do before going with a certain build order is to scout out your opponent so for example if your opponent is terran and you scout him building multiple barracks with a refinery then you know he is going to go marines and marauders in which you can counter with immortals and stalkers. Look up videos on youtube that's what really helped me out.
honestly build orders are useless after cybo. because at that point it is when you tech diverges. if you want to rush, build two gate no gas, if you want to tech build a forge first 2 gas and block, these kinda ideas as to what you want to do as a stratergy are more imrpotant than build orders that give you a rigid framework that are forgot almost instantly. heres what i do though while the ninth probe is building you should get 100 mins with it build a pylon. (should work out almost perfectly that you have enough for probe 10) when probe 10 comes out pylon should be done build a worker, the build a gateway (or a forge if you doing cannons) and thats about all i can give as concrete
