chubukovMaxSymmetricJamStackBinarySearch

Largest integer jam stack in [1, maxStackChips] with nonnegative symmetric-jam EV using exact HU equity vs a random hand; board 3–5.

chubukovMaxSymmetricJamStackBinarySearch(heroHoleCards: CardInput, boardCards: CardInput, deadMoneyChips: number, maxStackChips: number): number

CardInput is string[] or Uint8Array of deck ids 0..51. 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​

Push/fold study on a concrete flop/turn/river: equity comes from exactHuEquityVsRandomHand, then binary search finds max +EV jam depth. Board must have 3–5 cards.

How to use​

const hero = ['As', 'Kd'];
const board = ['2h', '7d', '9c'];
const dead = 150;
const maxStack = 5000;

const maxJam = poker.chubukovMaxSymmetricJamStackBinarySearch(
  hero,
  board,
  dead,
  maxStack
);
console.log('max +EV jam:', maxJam);

const eq = poker.exactHuEquityVsRandomHand(hero, board);
console.log('equity vs random:', eq);
