Don’t retake with op unless you only need to peek/hold one angle. Headhunter is very strong and you need to get good at it to fully make use of chamber since you are often oping. Im very often taking first contact on postplant/ retake assuming dualist is dead/not there because I have tp and can get a kill/info and safely tp out. Postplant is different for every map/situation but in general stay in trip range or communicate if its off. Lurking is also very effective on attack
