On this J♠ 7♥ 2♦ flop, start with the strategy grid, then look at the expected value of the available actions.

An example screen from a development build; the layout may change in future updates. The frequencies and EV come from one set of example solve settings and are not a recommended strategy. Your results depend on your ranges, bet sizes and other solve settings. Open the full-size screenshot →

  1. Find your hand

    The colored parts of each cell show how often a hand takes each action. Use the legend to read the mix.

  2. Compare the action EV

    Select a hand and read EV by action in the Inspector. Compare the expected value of the choices at that node.

  3. Follow the next decision

    Use the action tree above the grid to explore the next player’s options and later streets.

Trainer

Play through solved spots street by street. Each answer is graded Best, Acceptable or Mistake against the solver’s mix for the exact combo you hold, with the EV it gives up. Use the number keys to play fast.

From a hand to a study session

Your first analysis, in three steps.

  1. Recreate the spot

    Set the board, pot, effective stack and both players’ ranges in New solve. Start with a heads-up postflop decision you want to revisit.

  2. Run the calculation

    Choose your bet sizes and start the cloud solve. Your computer does not need to run the solver engine.

  3. Compare and review

    Open the result in Solutions. Compare action frequencies and EV, then follow the tree to see how the next decision changes.

On the free plan, each action supports one bet size, with up to two raises per street (all-in counts as that one size). Paid plans allow any number of sizes and up to six raises per street.

Questions about the solver

What is a GTO solver?

It numerically finds strategies that are difficult to exploit, given the ranges, bet sizes and other conditions you set. The output depends on those inputs and does not guarantee that you will win each hand.

GTO basics and solve settings →
Can I solve preflop or multiway pots?

Custom solves cover heads-up postflop in no-limit Texas Hold’em: two players remaining after the flop is dealt. You provide preflop ranges as inputs; the solver does not calculate preflop play, pots with three or more players, or ICM tournament strategy.

Do I need a powerful computer?

No. Cloud solves run on our servers, so a browser and an internet connection are enough. Solving on your own computer with the desktop app is optional and does not use your monthly cloud solves.

How do I start my first analysis?

Sign in, open New solve and enter the board, pot, effective stack and both ranges. The step-by-step guide walks you through the settings and how to open the result.
