Ok ok... Lately I've noticed that skill isn't as big a factor in CTF as simply knowing more about the game. It's like chess, really. There are certain areas that need to be covered with a limited number of "pieces." Once you can recognize the value of positioning oneself correctly it gets a lot easier to win matches. There are a lot of players out there who could be great at CTF if they only knew what they were doing, and so I released that guide.
I took your advice and created a section called "Positions" where I talk a little about each one. I added a bunch of other little stuff too. I'll keep adding as I think of it or if people suggest it. Of course, this is a public wiki and open to public editing.
