I found this post on the forums. The Original Poster(tGEmo) wanted to help the lower than Diamond players with their game and answer a lot of more detailed questions about improving your game other than. "Macro more, 4 gate, win." It is catered towards Protoss but somethings do translate to the other races.
To better read it, simply look for his posts, he always quotes the question in his post so no need to read every single post from every reader.
I'll try to add a few in this post as time goes by.
