Q u o t e: If I only had found it all those years ago... heh.
I think it will work perfect for SC2 too. I'll be surprised if you have to change more than 10 words. Change 50 and you'll have a guide for Age of Mythology. It really is excellent stuff and I'm surprised that the world isn't filled with guides telling you how to do economy and that you are supposed to learn economy first. It brings everything else into place. I actually think that the "next level" is kind of easier. Now that I have my priorities down I should be able to utilize all those strategies I've been reading about all these years.
Though it would be nice to know how to counter a (surprise) BC attack? I got lots of Scouts, despite reading about how lousy they are, and it worked fine. Cosairs are bad against the BC armour. Dragoons won't be able to protect my island expansions. Carriers take very long to build and can be brought down with Yamato if slightly outnumbered. (However: once I got rid of the main BC fleet, I transitioned into Carriers and finished him off)
I tried to shuttle probes, like you say. But managing it at the same time as everything else kind of got the best of me. Getting them out on the island I kind of managed, with some time. Getting them off the island again simply felt like too much work. Though practice makes perfect!
Also: the term "Manyarding". History lesson, please? :)
Given proper scouting (which should be fairly easy when you have observers), a BC attack shouldn't really be a surprise. There are lots of things that can counter BCs though. Dragoons do fairly well, given that there is ample room to shoot at the BCs (Challenger would be a little cramped though). Psionic storm can do a lot of damage, since BCs are slow and are air units (ie. they stack over top of each other and all take damage from storm). Stasis could also be another alternative, where you freeze half of their BC fleet and take out the other half.
I find that hotkeying shuttles/dropships makes it a lot easier to move things around, so if you're not doing that, give it a try.
Maynarding originates from a player name Maynard, who came up with the idea of building more than enough probes in the main base so that when an expansion was completed, a bunch of the probes in the main can be sent to mine at the expansion. The idea is you get an instant boost in your mining since you don't have to build up the required probes starting from 0. This sending of a bunch of probes is called maynarding.
