Exploitative play on an anonymous site

Hi,

I play on an anonymous site and use general exploits against fish/recs that share the same common imbalances and it has served me really well, however as ive moved up the stakes my competition has risen significantly and although there are still plenty of fish, I want to maximize my edge and exploit all of my opponents including ones that have a better understanding of how to play the game. However, as the site is anonymous, you maybe only have an hour to play against an opponent as they will often be moved to other tables, bust out, etc (MTT player), making it impossible to establish any history with your opponents. I have to assume from this that targeted exploits, like for example, imbalances in certain lines and nodes, check-raising, probing, and more niche or rare exploits can't really be performed? Am I incorrect / is this level of exploitative play totally unnecessary/unrealistic?

I wanted to ask what exploits and exploitative play may look like with this in mind? Is it just profiling your opponents and using basic exploits against them, memorizing commonly underbluffed/overbluffed lines and nodes, picking up what you can about any obvious imbalances that they may have etc and all of that fun stuff?

Any help or ideas is appreciated.

Thanks!
