So to conclude, profit is normally derived or optimally derived from seeking out worse players than you while losing as little as possible to the bad players, and i will add: the terrible players.

Coz i think terrible players either give you all their chips or take all yours. There's little midde ground. I feel in some ways a terrible player can be as tricky as a highly skilled player. They call with 80% of hands (for example) so we can barely put them on anything, call all cbets, so we still can hardly put them on anything and you can see the danger (this was an example from last night). So i just wanted to add that in.

So yes, seek out the fish and i guess there's still tons of theory in learning how to exploit them the most and how to avoid losing to them. Maybe this is all stating the obvious though.
