Changelog

New

• Added a job queue that lets you enqueue solutions for batch solving.

• Added high-resolution 5k flop and turn abstractions for preflop solutions.
• You can now isolate action ranges by clicking the strategy bar segments under the matrix.
• Ranges can now be filtered by equity buckets. The number of buckets can be configured in Settings.

Improved

• A new strategy weighting scheme for the multiway algorithm that produces more stable solutions in small trees and stronger strategies overall (up to 0.5bb/100 compared to the previous version).
• 2-player postflop solutions now reach high accuracy targets up to 25% faster.
• Minor (~5%) raw speed improvements to both algorithms.

The highlight of this update is an optimized postflop 2-player algorithm, making RocketSolver the first desktop solver to offer both multiway and heads-up state-of-the-art algorithms.

New

• Optimized postflop 2-player algorithm:
  • Best-in-class performance, beating all equivalent public products in strategy convergence speed.
  • Rake support, including flat drop rake.
  • Extremely small partial save files.
  • Low memory requirements.
  • A special “Compact Mode” allowing you to reduce required memory by up to 50% at the cost of a slower river strategy convergence rate.
• A new way to automatically extract non-initial street subtrees, including ranges, into a new RocketSolver instance for resolving.

Improved

• Up to 2x faster file saving.

Fixed

• Fixed a regression that could cause incorrect rake calculation in some preflop solutions with the “No flop, no drop” rake.

Fixed

• Fixed a bug where passive actions could not be added when the action limit was reached.

New

• Postflop node-locking is finally here. You can now lock strategies on the initial street in your flop/turn/river solutions.
• Added support for the flat drop rake structure. This allows you to take the jackpot rake into account or better simulate your offline games.
• A “Clear tree” button has been added, allowing you to quickly reset the tree to its original state by removing all bets and raises.

Improved

• The node-locking UI has undergone a major overhaul:
  • The “Lock strategy” button now opens a panel on the right instead of a modal window.
  • You can use Space to enter the node-locking UI and switch between its modes.
  • You can use Ctrl+C and Ctrl+V without entering the node-locking UI to copy and paste full node strategies between RocketSolver instances.
  • You can now brush hands in the matrix and strategy table without selecting them first. Hold Ctrl to lock the current strategy instead of the custom one. Right-click to clear the lock.
  • You can now undo changes with Ctrl+Z.
  • Holding Alt during node-locking will show the original strategy.
• The entropy formula has been reworked. The range of values is now more stable across various trees and abstraction options.
• A strategy bar displaying the total strategy has been added to the Strategy tab.
• Added a “Call to all-in threshold” setting that can help avoid unnecessary cold calls in multiway trees with asymmetric stack sizes.

New

• Panorama is a new feature allowing you to view strategies across multiple preflop nodes simultaneously in a grid format. For example, when opened from the root node, it displays RFI strategies for all players. You can navigate between the nodes by clicking the actions in the average strategy bar.
• The new “Bunching Ranges” feature now allows you to specify folding ranges for players who are no longer in the game, taking the so-called “card bunching effect” into account. This greatly simplifies the process compared to the previous need for tree pruning and node-locking.
• New settings for “Max number of calls” and “Max number of limps” limit consecutive calls to drastically reduce the size of large multiway trees. Calls that close the action are always allowed.

Improved

• The main window is now resizable.
• Increased the maximum stack size to 1000 bb.
• Added a turn abstraction with a size of 2000 for flop solutions.
• The IP/OOP bet sizing filter is now available for postflop.
• The tree population process can now be canceled in progress.
• Improved handling of out-of-memory errors when saving solutions.
• The “Lock strategy” dialog’s strategy bar now shows corresponding actions on hover.

• Ctrl+E has been added as a shortcut for clearing the range in the range input dialogs.
• It is now impossible to accidentally create a postflop solution with a 0 pot.
• In the “Create new solution” dialog, the dead money and pot inputs no longer share values.
• Improved and added tooltips, alongside smaller visual improvements and performance optimizations.

Fixed

• With the main window now being resizable, a longstanding issue where part of the window would not fit on the screen due to Windows display scaling settings has been fixed.
• Fixed a bug that sometimes caused the preflop relative position filter to be applied incorrectly.
• Fixed a bug that could result in squeeze bet sizings leaking into other spots.

New

• Added support for incremental bet sizings. This feature allows for conveniently taking limpers or cold callers into account when adding preflop raises. For example, entering 2.5bb+ as RFI will automatically increase the final 2-bet size by 1bb for each limper. Using 3x+ as a 3-bet can spare you from having to specify the squeeze size manually. Long form is supported as well if you want to use a different increment, e.g., 9bb + 2.5bb.
• Geometric bet sizing is now supported. You can now enter e to let the solver select the appropriate bet size automatically, or specify the number of bets to split the stack into yourself, e.g., 2e.
• You can now use the Min bet sizing to add a minbet or a minraise.

Improved

• A new option is available to take rake preflop only if there was a 3-bet.
• Added turn and river abstractions of size 100 for preflop solutions to better accommodate solving complex full-ring games.

• The “Convert bets to all-in” threshold setting has been split into two: one for preflop and one for postflop.
• Bets are now uniformly displayed as big blinds on preflop and as a percentage of the pot on postflop, regardless of which bet sizing options were used to add them.
• You can now use “bb” bet sizings on postflop.
• Bet sizes less than the minimum allowed bet size are now automatically converted to the minimum allowed bet size when applied.
• For Pot-Limit trees, bet sizes are automatically capped at pot bets when added.
• Range import now supports the “plus” syntax (“66+”, “A5o+”).
• A “Clear” button has been added to the “Select board cards” dialog.
• More fields now support Tab navigation.
• Additional UI rendering performance optimizations have been made.
• Significantly reduced the number of cases where performance might throttle when the app is in the background.

Fixed

• Fixed an issue where the Numpad’s Enter key could not be used to enter bet sizings.
• Resolved an issue where the strategy matrix failed to properly account for dead cards when calculating cell height on postflop.

Fixed

• Resolved a visual bug that could result in an incorrect layout of the range dialog, potentially obscuring the “Save changes” button.

New

• Strategy table filtering is now available. You can now filter the strategy table on postflop by toggling hand categories. Left-click a category to view only matching hands, or left-click with Ctrl to exclude them from the table. A new “Clear filter” button has been added for convenience.
• You can now copy and paste full node strategies between solutions.

New

• The long-awaited 9-max support is finally here! Now you can solve trees with up to 9 players.

Improved

• RocketSolver now suggests the last-used folder for saving and loading bet size population rules.
• Additional hotkeys have been added: Ctrl+N for “New solution”, Ctrl+S for “Save solution” and Ctrl+O for “Open solution”.
• Most modal dialogs now support closing on Escape and confirming on Enter.
• The “Create solution” dialog now supports keyboard navigation with Tab for stack and blind inputs.
• The save dialog now pre-fills the filename with the currently open file.
• All possible positions are now available in the cold call filter, to better support straddle or multiblind trees.
• A lot of work has been done to improve out-of-memory error handling.
• Additional optimizations to the core engine were made, resulting in ~5% (on average, depending on hardware) speed improvements.

Fixed

• Resolved an issue with some trial users being unable to activate their license.
• Improved support for running RocketSolver inside virtual machines (Windows only).
• Fixed a bug that could cause Fixed Limit trees with straddles to be incorrectly populated with bet sizes.

New

• You can now specify bet sizes for specific spots such as:
  • Isolation raises
  • Squeezes
  • Donks
• Introduced a preflop IP/OOP filter, allowing you to use different bet sizes depending on a player’s relative position.
• Added a postflop pot type filter, allowing you to apply different bet sizes based on pot type (URP, SRP, 3BP, 4BP+).

Improved

• Multiple minor visual changes have been made to improve the overall user experience.

Fixed

• Fixed a bug that in rare cases could cause some bet sizes to be incorrectly rounded down during tree population.

Fixed

• Fixed a bug that prevented new users from starting RocketSolver version 1.5.0.

New

• Added an EV display mode to the strategy matrix. Now you can switch between Strategy, Equity and EV.
• Introduced the ability to make partial saves. By saving strategy for only certain streets, you can drastically reduce the resulting file size. Partial save files are intended for storage and don’t allow you to continue solving from them.

Improved

• While creating a new preflop solution, you can now select which player will act first. RocketSolver always suggests a sensible default.
• Extended the available cold call filter to include 5-bets.

Fixed

• Straddle support, introduced in 1.4.0, caused a regression for files with an equal blind structure saved prior to 1.4.0. This issue has been resolved and all such files should now open normally.
• Fixed the bug that occasionally caused the poker table content to get shifted off-center.
• The rake % value is now properly rounded to 2 decimal places when loading from a file.
• Fixed a bug that made the main window’s close and minimize buttons unclickable when certain modal windows were open.

New

• Removed the limit on Rake %. You can use 100% rake with a rake cap to simulate a flat drop rake structure.
• Many minor visual changes and fixes.

New

• The strategy matrix and strategy table now also display equity for each hand.
  • To avoid taking resources away from the actual strategy solving process, equity is calculated with a precision of ~1 percentage point.
  • Equity calculation can be disabled while the solver is running on the Settings tab, potentially increasing the solver’s speed by approximately 1-4%.

Improved

• Added a weighted view to the range breakdown and made it the default. The “Weighted cells” checkbox now controls the view mode for both the strategy matrix and the range breakdown.
• You can now manually add Fold nodes to a tree, even if the current player is not facing a bet. This allows for building game trees for push-or-fold games.
• Range inputs now support the Simple Poker product family’s weighted range syntax, e.g. [50.0]AA, KK, QQ[/50.0].
• Range inputs now also support various hand ranges in addition to the already supported pocket pairs, e.g. A5s-A2s, T9o-T5o.
• RocketSolver now suggests the last used folder when opening or saving a solution.
• Relaxed rake cap restrictions to allow for much larger values.
• Additional adjustments were made to the UI to improve its appearance on large resolution screens.
• To prevent accidental sharing, your license key on the Settings tab is now hidden by default.

Fixed

New

• You can now specify raise size as a multiplier of a previous bet or raise, for example, 2.5x or 3x.
• You can now disable adding 2/3/4-bet cold calls by position on preflop, allowing for more control over tree building.
• You can now select an alternative color theme inspired by PioSolver in the Settings tab.

Improved

• The UI has been adjusted to scale better with screen resolution.
• Hovering over a hand category in the range breakdown view now isolates relevant hands in the matrix.

• A checkbox has been added to switch between full height and weighted height strategy matrix views.

Improved

• Added draw hand categories to the range breakdown list.
• Added a 7-day free trial period for new users.

Fixed
