Monte Carlo

Hole, board, and dead-card arguments use CardInput: string[] or packed Uint8Array (deck ids 0..51). See Card notation.

• simulateHandOutcome — Estimated equity vs one or more random villain hands (default villains = 1).
• simulateHandOutcomeAsync — Non-blocking MC equity (libuv thread pool); optional AbortSignal.
• parallelHandSimulation — Same with C++ worker threads and distinct seeds per chunk.
• parallelHandSimulationAsync — Non-blocking parallel MC; optional cancellation.
• simulateHandOutcomeBatch — Many MC spots in one call → Float64Array.
• simulateHandOutcomeBatchPacked — Packed holes/boards/meta batch.
• exactHuEquityVsRandomHand — Exact HU equity vs uniform random villain hand; preflop or board 3–5 cards.
• simulateHandOutcomeDetailed — MC equity with SE and Wilson CI.
• simulateEquityVsRange — MC vs weighted villain range.
• exactHuEquityVsRandomHandAsync — Non-blocking exact HU equity; optional cancellation · exactHuEquityVsRandomHandBatch
• straightMadeFlopToRiverExactProbability — Exact probability of straight or better in hero’s best 7 after uniform random unordered turn+river from remaining deck.
• straightMadeFlopToRiverExactProbabilityAsync — Non-blocking exact probability; optional cancellation

Multi-way MC (villains > 1) awards 1 / tiedAtBest when hero ties for the best hand. See Numerical semantics.
