PokerKit Plus

Fork-free capability extensions on top of PokerKit.

pokerkit_plus is a drop-in superset of pokerkit: it re-exports the entire upstream surface unchanged and adds new capabilities on top via subclasses, free functions, and thin wrappers. The upstream package is never modified, so PokerKit Plus keeps riding upstream's maintenance (correctness fixes, new parsers, etc.).

# Anywhere you used pokerkit, you can use pokerkit_plus instead:
from pokerkit_plus import NoLimitTexasHoldem, Automation, State   # all of pokerkit
# ...plus the PokerKit Plus additions as they land.

Design

• Form: standalone extension package, pip-depends on pokerkit==0.7.3 (pinned).
• No fork, no monkeypatch. PokerKit is built for fork-free extension (_begin_/_update_/_end_ phase hooks, mixin-composed variants, injectable rake/divmod, ClassVar registries). Most additions need zero core edits.
• compat.py pins the pokerkit version and is the single home for stable aliases of version-fragile upstream names.

Status

Semantic layer P0/P1 implemented (drop-in superset of pokerkit + first capabilities):

• pokerkit_plus.texture — BoardTexture.from_board plus Wetness, Connectivity, RankBand, StraightDraw, FlushDraw, and are_two_tone/are_monotone/are_rainbow.
• pokerkit_plus.combos — Nuts.from_board, CategoryCombos.from_board, HoleCombo, made_label, meets, CATEGORY_ORDER (made-hand category is pokerkit's own Label).
• pokerkit_plus.draws — Draws.from_hand (hero flush/straight draw + nut rank) and the shared NutRank.
• pokerkit_plus.tags — HandTier.from_hand (made-hand tier + labels()) with PairTier/KickerTier/TwoPairTier/ThreeOfAKindTier.
• pokerkit_plus.outs — Outs.from_hand (category-upgrade outs, grouped).
• pokerkit_plus.blockers — BlockerReport.from_hand (count-based: how many of the board's nut combos a holding removes).
• pokerkit_plus.ranges — ComboClass/expand_range (notation), build_value_range, calculate_range_advantage (Monte-Carlo equity), and nut_advantage (exact nut-category share).
• pokerkit_plus.facade — HandReport.from_hand and BoardReport.from_board, the one-call composed entry points for callers wanting a complete reading.

Built on pokerkit's lookup-table total order (no hand-rolled scoring); every per-board / per-hand enumeration is memoized, and equity is delegated to pokerkit's Monte-Carlo sampler. Verified: mypy --strict clean, ruff clean, unit tests + doctests green, Nuts/Outs/blockers match brute-force oracles, and a 2000-hand sweep shows no is_nut/nut_rank contradictions.
