Saving and Loading Sims

Go to Sim > Save Sim in the toolbar. A submenu appears with a "Save through" street picker:

Save Through Street

The street picker controls how many streets of strategy data are included in the file:

Only streets at or after the tree's starting street are shown. For example, a flop tree shows Flop, Turn, and River options but not Preflop.

Why not always save everything? File size. A full preflop tree solved through the river can produce .iks files that are gigabytes in size. If you only need preflop ranges, saving through Preflop produces a file that is orders of magnitude smaller. For postflop work where you only care about flop play, saving through Flop avoids storing turn and river data you may not need.

After selecting the street, a save dialog appears. Choose a filename and location. The .iks extension is added automatically if not provided.

The status bar shows "Saving sim..." while the file is written, then confirms the save path.

Go to Sim > Load Sim in the toolbar.

Select an .iks file. IkaSolver loads both the tree structure and the solved strategies. After loading, you can immediately browse the results in the strategy grid, hand frequency table, and other result views.

Loading a sim replaces any currently loaded tree and results.

IkaSolver can export preflop strategies in a format compatible with PioSolver. Go to Sim > PIO Export.

A save dialog asks for a "sim name" (not a full file path). IkaSolver creates a directory structure at the chosen path with individual range files that PioSolver can import for postflop analysis.

PIO Export is available whenever you have solver data (either from a fresh solve or a loaded sim). It exports the preflop strategies for all positions.

.iks file sizes depend on:

• Tree size - More nodes means more strategy data. Multi-way pots and many bet sizing options create larger trees.
• Save-through street - Each additional street adds substantially more data.
• Abstraction - Higher bucket counts and finer textures produce more strategy entries and larger files.

Typical sizes:

• Preflop-only save: 1-50 MB
• Full preflop tree through river: 500 MB - 5 GB
• Postflop tree (single flop): 10-200 MB

• Save sims after long solves. If you ran a million-iteration solve overnight, save the results so you do not have to re-solve if you close the application.
• Save through the street you need. If you are studying preflop ranges, save through Preflop. You can always re-solve for deeper streets later using the same tree file.
• Use descriptive filenames. Include the scenario in the name, like 6max_100bb_NL50_rake5pct.iks or HU_SBvBB_50bb_1M_iters.iks.
• Share sims with study partners. .iks files are self-contained - the recipient can load and browse without needing the original tree file.
