  • Update: HRC Beta

    July 11, 2024
    • Added the option to start postflop calculations on the turn or river
      • Select a turn or river decision and then use Hand: Create Postflop Calculation
    • Added bucketing options for postflop calculations:
      • Strict [HQ+]: Applies only suit isomorphisms, maintaining full hand accuracy.
      • Balanced [HQ]: Removes certain suit details, minimally impacting accuracy.
      • Relaxed [MQ]: Reduces complexity by discarding additional suit information, noticeably affecting accuracy.
      • IR, Imperfect Recall [LQ]: Employs the preflop calculation abstractions for aggressive merging across scenarios, with a significant reduction in quality.
      • Detailed descriptions of the new bucketing are included in the tooltips.
    • Introduced hand history generation for self-play solutions:
      • Generates hand histories from simulated self-play for further analysis in tracker tools.
      • Available via Hand: Generate Self-Play Histories
    • Note: You may receive an error message then HRC is restarted after the update. Simply manually launch HRC again in that case.
  • Update: HRC Beta

    April 09, 2024
    • Added additional hand setup options for PKO bounties:
      • KO-T$: Total bounty of that player (unchanged from older versions)

    • Fixed an issue where creation of Postflop Calculations failed with an error message.
  • Update: HRC Beta

    February 13, 2024
    • New experimental sampling mode for Monte Carlo hands:
      • Still in experimental phase; use with caution.
      • Increases sampling rate by skipping some updates in off-equilibrium branches.
      • CI calculations may vary slightly between modes. Aim for 10-20% lower CI with this mode.
    • Added equity model data to json exports:
      • Includes a new "equities.json" file for $EV (ICM/MTT/FGS) calculations, not available for chipEV.
      • Contains conversion factors for EV display modes and bubble factors for all players.
  • Update: HRC Beta

    January 31, 2024
    • Postflop hand creation via Hand: Create Postflop Calculation
      • Now accessible in viewer mode; full loading of the base hand is not required.
      • Board selection interface enhanced for better clarity.
      • Introduced an option to reconfigure sizings for the calculation.
    • Postflop: Fold-based EVs
      • EVs are now consistently displayed in comparison to folding, even when checking is an option.
      • Redundant fold options, present when checking is available, are calculated solely for EV reference and are not utilized in actual strategies.
    • General performance improvements for Monte Carlo sampling
      • Achieved a 10-20% improvement in performance.
      • Significantly reduced heap memory allocations during sampling.
      • More stable memory profile throughout the sampling process.
    • Removal of synchronization bottlenecks
      • Particularly beneficial when sampling simple hands or branches (e.g., subtree/postflop).
      • Most notable improvements observed on machines with high thread counts.
    • UI grid font tweaks
      • Enhanced font selection for various grid components, including the hand grid and board selector.
      • Optimized use of available space, resulting in slightly larger fonts.
    • Tree size estimates
      • Tree size estimates are now available for postflop hands.
      • Refined the estimates to be more accurate, particularly for low abstractions.
    • Added minor bugfixes on Febuary 3rd and 5th.
    • Download Beta Version
  • Update: HRC Beta

    January 18, 2024
    • Hotfix: A minor bug in the tree builder was introduced with the January 8th update.
    • The scripting API's getLastRaiseAction() method was incorrectly returning the last bet or raise of the current street, rather than the last raise action in the entire hand.
    • Due to this bug, trees configured using the UI failed to apply the c-bet sizing, defaulting to the regular flop bet size instead.
  • Update: HRC Beta

    January 16, 2024
    • Added support for importing prize structures in Sharkscope's JSON format during hand setup.
      • This provides an additional payout import option for Sharkscope subscribers.
      • HRC's native JSON payout structures, utilized by third party tools like HRC Ninja, remain unchanged.
    • Straddle tweaks:
      • Modified the "Add SB complete" option to include all players who posted a blind or a straddle.
      • Corrected an issue where the "Allow closing flats" setting incorrectly permitted the BB to flat call in hands with straddles.
    • Introduced a separate 3-bet OOP sizing option in the General Preflop settings.
      • This option is utilized in scenarios where none of the specific SB/BB 3-bet settings apply, such as in limped lines or hands with straddles.
      • If this new 3-bet OOP sizing is not configured, the default IP 3-bet sizing will be used instead.
  • Update: HRC Beta

    January 08, 2024
    • Added straddle options to the hand setup:
      • Off (no straddle)
      • Single (2bb UTG)
      • Double (2bb UTG, 4bb UTG+1)
      • Button (2bb BU)
    • Straddles are implemented as additional blinds, meaning:
      • Straddles do not count as a raise.
      • Calling the straddle counts as a limp.
      • Raising the straddle counts as an open raise.
      • A minraise preflop is double the size of the largest straddle.
      • A minbet postflop is equal to the size of the largest straddle.
    • Significant portions of the tree generation code have been rewritten in preparation for upcoming features.
      • The generated trees should generally be identical to those produced by the previous version.
      • An exception is in scenarios where limps are allowed and the BB player is all-in due to posting; a minor issue in this case has been fixed.
    • Increased the maximum worker threads at Window: Preferences: General Performance.
      • The recommended setting remains 0 (automatic detection).
      • This setting is typically only needed for systems with multiple CPU sockets.

    August 23, 2016
    • Parser update for Cake.
    • Added a configuration option to control the display of tournament equities (Window: Preferences: Equity Display):
      • Total Regular Prizes: This is the "classic" mode and displays equities as a percentage of the tournament's total regular prize pool. This total excludes bounties, so bounty calculations have equity totals of 100% + #players x bounty.
      • Table Equity: This mode normalizes equities so the sum of EQPre% values on the table equals 100%. For single table calculations this means the equities are displayed as percentage of the remaining prizes to be awarded, including bounties. The normalization factor can be displayed by hovering over the hand tab header.
    • The new "Table Equity" mode is intended to simplify working with large MTT calculations where EQDiffs% in relation to the total prize pool can become unhandily small. This mode also avoids inflated equities in bounty calculations by including bounty payoffs in the total.
