New

New Features

• Job queue — enqueue solutions for batch solving.
• Reworked flop abstractions for multiway solutions — consistently stronger solutions across all spots and boards. In benchmarks against the previous version the average improvement is +2-3bb/100, with outliers reaching +6-8bb/100.
• High-resolution 5k flop and turn abstractions for preflop solutions.
• Action range isolation — click the strategy bar segments under the matrix to isolate action ranges.
• Equity bucket filters — ranges can be filtered by equity buckets, and the number of buckets is configurable in Settings.

Improved

Solving Engine & Speed

• New strategy weighting scheme for the multiway algorithm — more stable solutions in small trees and stronger strategies overall (up to 0.5bb/100 compared to the previous version).
• 2-player postflop solutions reach high accuracy targets up to 25% faster.
• Minor (~5%) raw speed improvements to both algorithms.
• Saving solutions to file is up to 4x faster, plus a new check that the file is fully saved.
• EV tracking for additional streets requires 2x less memory.
• In multiway solutions only the initial street EV is tracked by default (changeable in Settings).
• You can now specify target Entropy before solving.

Interface & Workflow

• Preflop Panorama now supports an EV view.
• The hand table can be sorted by equity.
• Drag and drop solution files to open them.
• New hotkeys to switch between the Tree (T), Strategy (S) and Jobs (J) tabs.
• New button to return to the root node (hotkey R).
• New “Reset” button in the new solution dialog restores default positions, stacks and blinds for all players.

Game Setup & Rake

• Combined 3x + 1bb incremental bet sizing is now supported.
• New “Saw Flop + Pot size” condition for flat drop rake.
• A rake cap of 0 now means no rake cap (previously it disabled rake).
• Support for games where only the BU posts a blind.

Fixed

Bug Fixes

• Nodelocking could fail.
• EV rounding issue in the hand table.
• Hands in 2-player postflop solutions could be sorted by EV incorrectly.
• Blocked hands in 2-player postflop solutions were sometimes not hidden from the hand table.
• Memory requirement for multiway solutions was sometimes overestimated.
• Files could not be opened from Explorer if the PC was missing runtime libraries.
• A file solved on a CPU with a different architecture sometimes could not be loaded.
• Program window not fitting the screen with certain Windows DPI settings — now scaled down automatically.
• Various smaller issues and UI papercuts.

Version 1.15 is a major step for multiway solving: reworked flop abstractions, a new weighting scheme, batch solving through the job queue and much faster saving. Apply code 5050 at checkout and get RocketSolver with instant download through Courses On Budget.
