Import Strategies from HRC

Holdem Resources Calculator (HRC) is a powerful tool to build detailed preflop strategies. To actually train those strategies and build muscle memory, you can import them directly into Limp Lab. This article explains how to export your ranges from HRC and bring them into Limp Lab.

Step 1: Create a strategy in HRC

For a complete walkthrough of HRC itself, see the HRC documentation.

Open HRC and create a new Monte Carlo Hand (File → New Calculation → Monte Carlo Hand).
Set up the table and blinds to match your scenario.

HRC Table Setup

Note: Limp Lab currently supports only symmetrical stack structures (all players with the same stack size). Support for mixed stacks will be added in the future.

Once the table and blind structure are ready, click Next.
Define your pre- and postflop betting structures as you see fit. The HRC documentation explains these settings in detail.
Click Finish to start the calculation.

HRC Preflop Settings

When HRC finishes the calculation, you’re ready to export the strategy.

Go to the hand tab containing your new strategy.
In the toolbar, click Hand > Export Strategies.

Export Strategy Nodes

Select the nodes you want to export manually, or use one of the predefined export options.

Be careful not to export too many nodes at once. HRC can easily produce thousands of nodes, which is far too much for anyone to learn or train effectively. Using strategy this large will slow down Limp Lab. Focus on the **most common spots** you want to study, and leave out the rest.

Click OK.
Save the exported strategy as a .zip file.

Step 2: Import the strategy into Limp Lab

In Limp Lab, go to Explore → Preflop Strategies
Click the Import from HRC button.

Import Strategy from HRC

Drop the exported .zip file into the upload window.
Adjust the simplification settings if you want to round frequencies or streamline ranges.
Click Import.

Imported Strategy from HRC

Your HRC strategy is now available in Limp Lab and ready for training.

Simplify solver outputs for practical use

HRC outputs precise GTO solutions that often include highly complex mixed frequencies. While mathematically correct, they are almost impossible to execute in practice.

For example, a solver might recommend opening 43s from the Button 7.8% of the time and folding it 92.2% of the time. Instead of trying to memorize this exact frequency, you can use Limp Lab’s import tools to simplify the range into a clean, actionable decision – such as always opening, always folding, or using a rounded 10%.

This way, your imported strategies stay true to the solver’s intent but remain practical to apply in real games.

Next steps

Once imported, you can:

Practice the new strategy in the Range Trainer to build recall and execution speed.
Add Variants for different stack depths or ICM pressure spots.
Use tools like the Flop Navigator to connect your preflop strategy with postflop play.

The key to success is to **import selectively and simplify**. Focus on the spots you play most often, keep ranges practical, and train them consistently.
