It's not so much an interest in a special strategy, but rather a "how the heck am I supposed to see the opportunities".
I don't have much time for playing and often find myself playing along without any real focus.
In my current game as Hiawatha I totally forgot to press for my UU for example. Granted, on Prince I still managed to conquer neighboring Nutmeg-Guy (Polynesia?), but my got veritablily reckt when his Kris came into action. Had to quit the session yesterday, but I am not sure whether I'll be able to fend him off and avoid him regaining his capital.
Another weak spot I have is, where and when to build specialist buildings, how many cities to build and so on and so forth.
What I managed to use was Hiawathas Wood ability, for which I didn't need so many roads. But what about my pantheon for example? I took the one for mines on resources, as I hab plenty of amber around. But wouldn't something not limited to a few tiles be more efficient?
I think I still do know to little about the paths to other victories except conquering everyone :-D
Edit:
I think what I'd love to know is something like "OK, this is my civ, it's good for such and such approach and the following beliefs, pantheons and social policies support my strengths" (like your Brazil example)
