HRC Beta: Postflop Solver

At HoldemResources, we're constantly innovating and working to improve our software to provide you with the best possible experience. One way we do this is through the release of beta versions that include experimental new features for our users to explore and test. Public beta testing allows our users to get a sneak peek at the latest enhancements while providing us with critical feedback, helping to identify potential issues and areas for improvement. By participating in the public beta, you'll play an essential role in shaping the future of HRC and ensuring that our solver continues to be a reliable and effective tool for poker players worldwide.

Experimental Features

Available for testing:

  • Various general performance improvements
  • Display postflop strategies for preflop solves, using the configured abstractions
  • Alternatively, create dedicated postflop calculations starting from a specific flop
  • Specifying new sizings and customizing abstractions when creating postflop calculations
  • Basic postflop display options in the main hand grid include a per-combo display as tooltip and a suit filter
  • Displayed postflop EVs are in comparison to folding
  • Frequency based node locking (preflop & postflop)
  • Straddles


  • Viewer mode support for postflop saves
  • Option to add sizings / branches to existing hands

Viewing postflop strategies and calculating dedicated postflop spots are restricted to HRC Pro licenses.


The latest HRC beta version can be downloaded here:

Only download this version if you are comfortable with testing beta features. This version may introduce stability issues and other bugs. Once the new features are sufficiently tested, they will be integrated to the stable version. You can run the stable and beta versions on the same system, simply use different install locations.

Using the New Postflop Features

The latest HRC release brings you two unique ways to analyze postflop scenarios, all starting with a standard Monte Carlo preflop setup. Don't worry, if you're already used to setting up preflop scenarios in HRC, you'll find the postflop features easy to navigate.

For Best Results: Dedicated Postflop Analysis

The primary route to obtain detailed postflop strategies begins by picking a specific line from your preflop analysis. Then, click on "Hand: Create Postflop Calculation". HRC lets you choose a specific flop to zero in on, launching an individual calculation for that scenario.

Create Postflop Calculation

This new calculation inherits the equity model, preflop hand ranges (folded hands included for bunching), and your postflop betting choices from the original setup. After setting this up, this calculation becomes independent — meaning, any future changes to your preflop hand ranges won't affect it. To get the results, you'll need to select "Run Nash Calculation."

In this first release, we start postflop analyses on the flop, employing perfect flop buckets and utilizing 16k abstractions for the subsequent turn and river. We're planning to introduce features that allow for turn or river starting points and more bucket customization in future updates.

Quick View: Postflop Strategy Look-Up

Alternatively, you can now quickly explore postflop strategies from existing preflop calculations by clicking on the new "Board:" selector at the bottom of the hand tab. While this is convenient and allows immediate access to all possible boards, it's not as accurate due to the level of abstraction used for preflop solves.

Board selector

By default, our preflop calculations don't store average postflop strategies, which are not useful for preflop results. This means the postflop strategies you see may not be entirely accurate, especially for hands with mixed strategies. A small warning will appear near the bottom when viewing a node without averaged strategy data.

Missing strategy averages

If you want to improve the detail a bit, you can use the "Hand: Add Postflop Strategy Data" option. Your calculation will approximately double in size and will require new sampling to populate these averages. But, keep in mind, even with this extra data, it still won't be as precise as a dedicated postflop analysis.
