The first day of a new season...

Personally I like to put my first pylon near my ramp so no probes can sneak in without me knowing. This is just preference though and something to consider.

When you scout in PvP a major thing to look for is gas timings. Also it is ok to shift que a few moves with your scout while you do something in your main.

Also make sure to scout inside your base with a probe/first stalker at some point nobody likes losing to in base pylons.

Hotkey your Cyber Core, this will help you get WG research slightly faster. I hotkey it to what I hotkey my robo to so I juts overwrite the hotkey with my robo later on.

Since you were going for tech I would get your 2nd gas earlier, like 17-18 supply after you make your core

Scouting your opponents ramp and seeing their unit composition at around 5 minutes can tell you a lot about what build they are going. Count their sentries and zealots see how much gas they are spending etc.

Immortals take a lot of supply, anticipate your robo finishing and start that pylon early. Same goes for WG research prepare for the influx in supply with an earlier pylon.

Always make an observer immediately after your immortal in case of DT and to see what your opponent is doing. I sometimes make 2 if I suspect they may be getting DTs

You made a nexus without scouting him, This is extremely risky, make sure you know what they are up to before expanding.

In PvP it is also wise to at some point send a probe to every base on the map as lots of players like to hide bases in pvp

You got blink early but did not use it. Feel free to scout/harass with your blink stakers as it gives you map control, pretend they are mutalisks, pick off stray pylons and such, Bring an observer with them so you can blink up cliffs if you need to. Also charge is usually good to get if you are going gateway heavy.

I typed this as I was watching it so I saw you did blink harass later but you could have started a bit earlier I feel. Also keep your stalkers on a separate hotkey so you can get them out of bad situations quickly.

You saw he had a forge and that he was going for upgrades. Generally you want to stay even or ahead of your opponent on upgrades since they make a huge difference in mirror match ups.
Also you can blink back the weakened stalkers so that is something you should try and practice

Overall improve on your scouting and make your builds a bit more refined.

Keep your scouting probe alive to patrol outside of his base and see when he moves out. Also you can poke up his ramp and count his marines/marauders and see if he is spending his gas.\

Make 2 observers. You should always have one with your army in case of cloaked banshees and the like. Also it is good to have an observer spotting for drops. You made a 2nd one later which is good, but you left it next to a cannon which is unnecessary I would keep it with your army or spotting drops

You didn’t use your forge until a while after you got it. If you are gonna get it use it right away otherwise delay it. This isn’t too big of a deal but it will help.

I personally hate colossus vs terran. They are too easily killed by marauders and Vikings. I would encourage you to mess around with 2 forges pumping upgrades and gateway units with HT. Mainly zealots as HT cost gas.

Keep scouting all game long to see how many units they have and what types.

If you get a forge get upgrades dood! In PvT upgrades are good to get because you can chronoboost them and stay ahead on upgrades all game long.

ALWAYS use guardian shield vs terran, it makes a huge difference especially against marines. Just use 1-2.

Rofl at manner nexus

Overall. Upgrades and scouting. Also use chrono boost on probes more

Generally it is better to make your gateway on the outside so roaches cant snipe your zealot if there is an overlord to spot.

Vs Zerg scout their natural first then main bases so you can try and delay the hatch and see when it goes down.

You didn’t need to chronoboost your first zealot as you saw no lings were on the way.
Start warpgate research before your sentry. If you plan on making sentries its probably better to get 2 gas slightly earlier. When I 3 gate expand I get it around 20 supply. I can get 3 sentries and a zealot out before warpgate finishes.

Hide a probe on the map before ling speed is done so that you can scout for a 3rd base. Once ling speed is done the map belongs to zerg.

I feel you played a bit greedy and didn’t make enough units/cannons when you expanded before your stargate, but sometimes risks pay off.

Don’t chrono boost warpgates unless you are attacking or defending. It is better to use it on probes.

Also get hallucinate it allows for great scouting all game long.

I think you should have made your cannon a bit earlier in case of burrow.
On meta if you are close by air you can make a pylon in the top corner of your main and its basically a proxy pylon if you warp on the low ground, you kind of did this but not as effectively as it could have been.

HOTKEY YOUR ARMY! Also it may be wise you have your void ray hotkeyed separate as well. At least in 2 groups 1 by itself so you can micro is back easily.

Scout for a 3rd base from zerg

When attacking zerg’s natural ALWAYS forcefield their ramp right away. it makes a huge difference when they can only reinforce from 1 base.

Guardian shield helps vs roaches

Overall scouting and opener was a little weird and risky.

9 pylon (Chrono boost 11th probe)
12 gate (Chrono boost 13th probe)
14 gas
15 or 16 pylon
Cyber when gateway finishes. Warp gate immediately after core finishes, spend all chrono boost on warp gate.

Zealot and then stalker then another stalker out of gateway, while cutting probes at 20. This will leave you at 26/26 food. Build 3 gateways after first stalker out of gateway. Build another pylon, then push out towards his base with the zealot, stalkers, and a probe, building a pylon somewhere near it. Turn gateways into warp gates and warp in whatever you have money for (stalkers and zealots) Attack till he dies.
