How to use​

const jamStack = 4000;
const dead = 150;
const equity = 0.52;

const ev = poker.chubukovSymmetricJamEv(jamStack, dead, equity);
console.log('jam EV:', ev); // positive → jam prints +EV in toy

const maxJam = poker.chubukovMaxSymmetricJamStackChipsBinarySearch(
  equity,
  dead,
  10000
);
console.log('max +EV jam stack:', maxJam);
