• New Sampling Algorithm: Approximately doubles calculation speed compared to previous versions.
• Optimized Performance: Improved efficiency, especially in subtree sampling and on powerful hardware.
• Advanced Postflop Configuration: New tab in the hand setup with finer control over postflop betting options.
• Reworked Export Options: More control over exports, plus direct upload option to the Pairrd Trainer.

• Improved Tree Size Estimates: More accurate estimates, especially for small abstractions.
• PKO Bounty Setup Options: Specify total bounties of players or only the paid-out portion.

Classic Version Enhancements

• Increased Tree Size Limit: Doubled from 25,000 to 50,000 nodes.

Pro Version Enhancements

• Dedicated Postflop Calculations:
  • Handles heads-up and multiway pots with any equity model (MTT, PKO, etc.).
  • Supports full card removal and card bunching from all players, including those who folded preflop.
  • Simple setup directly out of preflop calculations, automatically copying the relevant ranges and game structure.
• Dynamic Action Editing: Add or replace actions or branches after creating a hand.
• Synthetic Hand History Generation: Generate synthetic hand histories from your solves for analysis in external trackers.

Unsupported Windows Versions

HRC v4 no longer supports end-of-life Windows versions, including versions prior to Windows 10 and Windows Server 2019. This is due to the fact that essential third-party libraries have dropped support for these outdated systems.

We strongly urge users to upgrade from these unsupported Windows versions. Continuing to use them poses a significant security risk due to the absence of ongoing security updates.

For users who are unable to upgrade immediately, we offer the previous HRC v3 version as a legacy option. You can download the installers for HRC v3 here. However, please note that HRC v3 is no longer actively maintained and will not receive any further updates.

Updating and Pricing

The update is available via Help: Check for Updates and is included with all active licenses. Installers are available in the download section.

We have made some adjustments to the pricing for new licenses. Existing subscriptions are not affected and will renew at their current pricing.
