Where is the proof?

> You're absolutely right that GTO does not guarantee you'll win the maximum against a fish, but neither does exploitative play. In fact, exploitative play can't guarantee you anything, which is probably why old-school pro players are perennially going broke throughout their careers (that and bad bankroll management).

I'm not arguing in favor of one or the other, I am just correcting the misunderstanding. In reality, you should adapt to the conditions at the table and your opponents habits, because "GTO" is only possible against perfect play to begin with, so you're always going to be playing slightly imperfectly. so is everyone, because you cannot know everything. And again, it's almost never the way to win the most money. It's a distinction not a lot of GTO nerds understand. I'm not arguing against it at all - I use GTO solvers to work on stuff a lot.

And I also never claimed exploitative strategies guarantee everything, for the same reason "GTO" doesn't either. It's a game of incomplete information. The skill comes in using incomplete information in making good assumptions - that is almost nothing to do with math. And, there are pros that have been winning for long amounts of time knowing zero about GTO theory.
