[G] insane AI strategy guide

As many know (or may not know), the best way to beat an insane AI is to take advantage of its overaggressive nature. So, all of these builds center around aggravating the computer which prevents mining while you prep and send in a quick rush force. It is very important that you keep your harassment worker alive as long as possible. There are 3 main phases to the strategy:

1) worker prep - how many workers to make
2) aggro - how to prevent the enemy from mining while building attack units.
3) establishment - establishing your presence in his base, defeating the computer

The AI works as follows. If a player structure is being built in the AI main, the AI will send workers to attack the building, and anything else within a certain range. This means that they will attack your structure, worker, and anything else that they see. Once the threat building is gone, the workers return to mine. So, if the AI workers ever give you too much trouble, just cancel the aggro building and they'll back off. This is very important for Terran players because your SCV is exposed while building. It's also important in co-op scenarios, because sometimes the enemy will attack your ally and kill him before you even notice as a result of your aggro, so be mindful. If your buddy is getting attacked, cancel to save him!

Also, the AI will make a judgment on whether it can win a fight or not. If it thinks it can, the workers attack you. If it knows it cannot win, the workers leave you alone and refuse to mine while the main structure is under attack.

In all cases, you want to quickly fight your way to his main command structure (hatchery/CC/Nexus). Make sure he has no attacking units. If his workers flee when you hit the main structure, you've won. If the workers attack you, the AI still thinks it can win, so mop up a few more workers and teach him otherwise! Then go back to killing the CC. With the workers not mining, the AI will quickly give you the gg.

Worker Prep

1) Send worker #7 towards enemy base
2) Send workers #8 and #9 to mine.
3) Halt worker production.
Note: Sometimes you can squeeze out a 10th, but only if the map is very large. You know you can do it if you can build #10 and still be able to build 2 pylons by the time #7 gets to the enemy base.

Aggro

1) As worker 7 arrives at the enemy base, build 1 pylon on low ground, move up onto enemy base and make a second pylon (aggro pylon).
2) Go back down to the first pylon. The enemy should start attacking the aggro pylon. They probably won't kill it. Either way, be sure to cancel it right before it finishes/dies.
3) After you cancel the 1st aggro pylon, you should have approx 250 minerals. Wait until 300 and build 2 gateways outside his base.
4) Continue making/canceling aggro pylons while the gateways finish.
5) As soon as the gateways are done, chronoboost 2 zealots and send them to defend the aggro pylon.

Establishment

1) Continue making/chronoboosting zealots.
2) Allow the aggro pylon to finish when you know that your first 2 zealots will be able to defend it. This frees up extra supply so you can make zealots #5+.
3) send in zealots and hack away at workers. The enemy will probably have 1-2 attacking units by this time, which should be very easy work for the zealots.
4) March into his main base and hit his main structure to win.

Worker Prep

1) Send the first worker to return home with minerals over to the enemy base for aggro.
2) Send workers 7 and 8 to mine, halt production

Aggro

1) about the time your worker gets to his base, you should be able to throw down the spawning pool, do so.
2) As soon as you can, steal the gas.
3) Continue to gas steal/cancel until your attack force eventually arrives.
4) Right about the time of the first extractor cancel, you should also be able to make an OL, do so.
5) As soon as your pool finishes, make 6 zerglings and have them rallied to the enemy.

Establishment

1) Continue making that extractor until your zerglings arrive.
2) Continue making zerglings as larva become available.
3) When the first batch of zerglings arrive, have your extractor drone join the fight, but watch his health. It's important to keep him alive, so if he gets to about half life, be sure to put him make on extractor duty. Also, if you're fighting a Zerg, you could consider turning him into a spine crawler.
4) By the second or third wave of zerglings, the AI should be beaten back.

Note: Protoss is by far the most difficult for Zerg to take out, just be aware that it takes 4 zerglings to win a fight vs a zealot, and you barely win.

By far the most difficult race to work with, but still a doable strategy for low-league players.

Worker Prep
1) Send SCV 7 and 8 to enemy base. Halt production
2) Have SCV 7 build a supply depot whenever you can afford it. It'll be somewhere near the middle of the map
3) SCV 8 will arrive to the enemy ramp first, so have him begin the barracks.

Aggro

1) Send 7 into the enemy base and begin a supply depot, quickly pull him off and aggro enemy workers and cancel the SD when things get dicy.
Note: you can simply cancel the SD whenever you first see enemy workers if microing isn't your thing.
2) Continue aggroing.
3) With the barracks finished, make a marine, and have 8 build a bunker at the edge wall of the enemy base.
4) Have the lone marine join the aggro fun, but keep him alive!
5) Keep aggroing until the bunker finishes (around the time your second marine arrives).
6) Send your guys into the bunker, put 8 on autorepair.

Establishment

1) Continue making marines.
2) Change your aggro supply depot into an aggro bunker, as close to your 1st bunker as you can, but on the high ground.
3) The 1st bunker should be able to shoot enemy workers that come to kill your second bunker, which should then make the workers leave the 2nd bunker alone and attack the 1st.
Note: This is the most difficult part and is difficult to say what EXACTLY to do. Just try to use common sense to aggro the enemy.
4) Sometimes the workers won't come attack bunker #2, so you hafta unload from #1 and march up the ramp. The workers attack, you run back down and into #1.
5) When bunker 2 finishes, unload from 1, load into 2, salvage 1.
6) Use bunker 2 as a safe spot. Use marines to push into enemy main and return to bunker if there are any problems, then push out again, etc.
7) You can make more bunkers if you want, but it's probably better to build a second barracks; most of the enemy workers should die while establishing bunker 2. You can even build rax2 on the the high ground.
8) Continue making marines and pushing in until you win.

Sometimes the enemy base is shared, which means you'll end up aggroing both enemies at once. The rule of thumb for shared bases is this: bases are shared if there is only 1 choke into the enemy base. In this case there are a few things to watch out for.

1) Only 1 of you needs to aggro, the other can focus on rushing faster. It's best for the Zerg to aggro due to low extractor cost.
2) If you're aggroing, be aware that you will be attacked by twice the workers, so you have to pay twice as much attention to not let your building die twice as fast! (or 3x if you're playing 3s)
3) Watch your buddies! Sometimes the aggro'd enemy will go and directly attack your ally who's building outside the enemy base. Canceling your aggro structure will call the enemy off him. In this case, it's usually easier to watch your ally and cancel when the enemy gets close to him, rather than watching the health of your building.

Also, Tempest is the worst map possible, the enemy can spawn in 3 locations, it's usually best to restart if you get that map. However, if you're trying for the streak achievement, it's still winnable, just have a T or P player send 2 scouts instead of one, and have each scout go to a different base (the 2 from the T or P, then the 1 from the ally). It might be most helpful to have the T just split his 2 initial workers.

Getting the AI to gg:
Meet these conditions and the AI will gg
1) Neither AI has an attacking unit.
2) Both AI have structures that are under attack.
3) Both AI have given up mining
4) Only 1 human player remaining.
In other words, the AI will give up just like in 1v1, but only 1 human can be present for the gg to be given. Also, don't accept a gg before 5 minutes, it may not register the win! This does not seem to be the case in 1v1, so feel free to gg whenever
