Map control help

So, I was playing on asylum and our team didn’t start off too well. But we ended up picking people off and taking control of the middle ring. We were then able to catch them off spawn and keep them pinned on their side. We were then able to tie the score and eventually we beat them

Winning like this was so satisfying. Actually controlling the map and deciding which battles you want to persure.

So far, I only know how to do this on asylum. I learned this from watching a lot of mlg streams in sanctuary. Does anyone know how to do this for other default reach maps? (reflection, sword base, the cage, etc). If there’s a guide on this, then that’s even better.

Thanks
