* You can loot corpses (easier if you can hide/camo)

To cover your other points, you need to learn the way of the land.
Knowing how to chase is nothing more than checking where your
opponent is and predicting where he will run to.

If you have the layout of most areas in the mud in your mind, then you can immediately place someone just from typing where once or twice. You also
know how to put max distance between you and him as fast as possible, if needed.

I'd concentrate first on learning geography. Try and focus on the areas you
find yourself a lot first and learn to be comfortable in them. Ideally, you should
be able to navigate completely blind.

Once you know the most frequently traveled areas, you can focus on trying to kill enemies/skills/tactics etc.
