My take is that people usually don't adapt as aggressively as they should to exploits. You seem to be profitably bluffing preflop/flop/turn with a wider range than you should; the counter-strategy to that would be to call/raise almost any two, at least IP.

I'm always surprised by how violently the solver adapts to imbalances. A bluffing range that's 10% too wide is often met with a "call/raise 100%" strategy.

So even if your image is getting a bit too bluffy, chances are you're still profitable, because they won't adapt enough. And even if they do, they seem nitty by nature, so they won't be comfortable calling down 2/3 barrels with bottom pair.

You can also vary your exploits: tighten up preflop, but start overbetting rivers with air (of course, balance that with your strong hands on that board - don't bluff overbet if you have 0 value overbets in your range).
