straightMadeFlopToRiverExactProbability

Exact probability of straight or better in hero’s best 7 after uniform random unordered turn+river from remaining deck.

straightMadeFlopToRiverExactProbability(heroHoleCards: CardInput, flopThree: CardInput, knownDead: CardInput): number

All three card lists use CardInput (string[] or packed Uint8Array). See Card notation.

Import​

const poker = require('poker-calculations');

ESM (Node):

import { createRequire } from 'module';
const require = createRequire(import.meta.url);
const poker = require('poker-calculations');

When to use​

Use when a pattern-based runner model is not enough and you need the exact flop→river chance that hero’s best seven-card hand is a straight or straight flush. Pass villain/blocker cards in knownDead so they are removed from the deck.

How to use​

const poker = require('poker-calculations');

const pStraight = poker.straightMadeFlopToRiverExactProbability(
  ['9h', '8h'],
  ['7h', '6d', '2c'],
  ['Kh', '5s'],
);
console.log(pStraight);

flopThree must be length 3; knownDead may be empty.
