I need help learning to play versus. I used to play StarCraft at LAN parties all the time. I destroyed my friends, and never broke a sweat. I never worried about perfecting build orders, never put to much thought to managing my population and making the best use of my resources. I relied on my micro and quick thinking. I knew which units worked well in specific situations, and I just winged it.
I just got StarCraft 2 a few days ago. I've played 3 practice matches (the really slow ones that you get 50 of when you start the game). I won two, and lost one. For someone who has had a lot of experience with StarCraft, this is INCREDIBLY disappointing. I've been trying to brush up with medium computers, and while I've never lost, I consistently beat the computer by a tiny margin. I don't have a chance in hell playing competitive online right now, but I would absolutely love to learn.
Are there any resources for learning to play like the pros? Descriptions of why certain decisions are made, dos and don'ts of competitive play, and general strategy overview?
