Yeah I think you're right. just playing an equilibrium is suboptimal in the sense that it doesn't extract maximal value from the opponent. You want to be playing a best response to the opponent's strategy. That's what you see online poker players do. They model their opponents (in the sense of labeling them as fun player, too tight, too loose, etc), then try to predict their hands based on their moves. Otherwise I guess they would be losing money: poker is zero sum by its nature, and the casino's cut on top of that makes it negative sum!
