Here I asked how to beat AI in 5 minutes on medium level.
I played as Terran. The key was to start barracks building close to opponent base (and use small map). I was successful on Medium, then on Hard...but on Very Hard my best time with Terrans was 5m2s... but usually it takes 5m30s, 6m15s... I couldn't find the quicker way... So I switched to Protoss...
Finally, I've beaten the A.I. in 4m40s, and now I'm itching to beat the A.I. on Insane level. I did that with a lot of effort on Very Hard, but I'm afraid that my strategy won't work for Insane.
I will probably try to cannon rush, but I'm not sure if it will help.
Please advise: what race, what strategies?
I haven't tried it myself yet, and I don't see any good strategy.
On Very Hard with Protoss against Terran I played in such way:
In the very beginning build new Probe - it will go to build a Pylon close to enemies base; build Pylon, Gateway, Gateway, Gateway - 3 gateways. Why? In order to get enough zealots quicker. After building 3rd gateway my probe is going to disturb their SCVs. It is not actually too successful, but it is boring to sit and wait for 1st zealot. When 1st gateway is completed you should have enough money for 1st zealot. it should go to opponent base and run close to Barrack/SCVs. While there are no marines - kill SCVs (don't get them to surround you. when marine appears - kill him with zealot. Keep producing zealots, when you reach supply limit - send your probes to die - you will get 1 more zealot. If you have money you can build 1 more pylon and train more zealots, but 6 was enough for me (2Pylons=>18 food - 6 probes=12/2 = 6 zealots).
I found this tactic almost from 10 attempts, and final time was 4m40s.
I did that on... the 1st map in the list (please let me know what it's named, I don't remember that).
I don't think that will work on Insane. Probably I need to build 2 gateways and get 3 probes with myself to push AI...?
P.S. BTW, such practices help to improve your micro: handling those zealots/probes against SCVs/marines :)
