| # range-reader-v0.1 |
|
|
| 613,399 No-Limit Hold'em hands in [Open Hand History](https://hh-specs.handhistory.org/) format (spec 1.4.7), one JSON record per line with a blank seperator line. Hole cards are shown for every seat. This is the training set for [range-reader](https://github.com/elliottneilclark/range-reader), which predicts a villain's hole cards from the action. |
|
|
| ## Generation |
|
|
| Self-play from [rs-poker](https://github.com/elliottneilclark/rs-poker)'s arena: |
|
|
| ```bash |
| rsp arena generate ./examples/configs -o out_min-2_max-6.ohh -n <hands> |
| ``` |
|
|
| Cash games, 5/10 blinds, randomized stacks, 2- to 6-handed (even split). Five agents, four built on counterfactual regret: |
|
|
| | Agent | Type | Notes | |
| |---|---|---| |
| | `CFR-Configurable` | real-time CFR | known-card estimator, coarse bet sizes | |
| | `GTO-Experiment` | real-time CFR | — | |
| | `6Max-RFI-GTO`, `Pekarstas-6max-RFI` | preflop CFR chart | fixed open ranges | |
| | `RandomPotControl` | pot-control heuristic | not CFR; call odds scale with pot, plus noise | |
|
|
| ## Caveats |
|
|
| The CFR is a real solve, but bounded — strong on the immediate decision, thin past it: |
|
|
| - Up to 2048 ms per decision, 128 root iterations, regret-convergence early stop, root width set to the core count. |
| - Lookahead thins fast — one iteration and width 1 below the root, so multi-street planning is shallow. |
| - Coarse action abstraction: a handful of bet sizes (~2.5x raises, ⅓/⅔/full pot, shove). |
| - Charted agents play fixed preflop ranges; the pot-control agent is a heuristic. |
|
|
| Expect competent, varied poker — short of a full-tree Nash equilibrium. |
|
|
| ## Schema |
|
|
| Each line is `{"ohh": {...}}`: table and blinds, `players` with seats and stacks, `rounds` of streets, and per-street `actions` (post, deal, fold, call, raise, all-in). Dealt cards carry the `cards` field. See the [OHH spec](https://hh-specs.handhistory.org/). |
