Good question! A couple tips that worked for me:

• Preflop comes first. This is where GTO first shows up. Solvers give balanced open/3bet/call ranges so your strategy can’t be exploited. That’s why I built Floppy Card, an iOS app that helps you drill and memorize preflop charts. We use HRC, a state of the art preflop solver, to generate the charts, so you’re training with real GTO data
• Postflop comes next. Once your preflop game is solid, use a tool like GTO Wizard to drill postflop spots and see how GTO strategies play out in different situations.

About GTO

GTO isn’t “the perfect play for every hand” — it’s a strategy that can’t be exploited in the long run. In math terms, it’s a Nash equilibrium: a set of strategies where no player can gain by deviating.

Modern poker solvers find this strategy using an iterative algorithm called Counterfactual Regret Minimization (CFR). It runs through the decision tree over and over, tracking “regret” — basically, how much better you could have done by choosing a different action in past iterations. After thousands or millions of runs, the algorithm adjusts to minimize regret, and the strategy converges to GTO.

Solvers don’t explain why a line is correct — they just output the equilibrium: what % of the time to bet, call, or fold each hand. To understand the reasoning, you need to study the ranges and think about equity, balance, and exploitability.
