expectedValueCall

Chip EV of calling once vs folding (fold EV = 0). No future streets or implied odds.

expectedValueCall(equity: number, pot: number, toCall: number): number

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 you have a single-street win probability and want chip EV of call minus fold. Positive EV means call is better than folding immediately. For live cash games with rake on the final pot, use expectedValueCallWithRake instead.

How to use​

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

const equity = 0.4;
const potBeforeCall = 90;
const toCall = 30;

const evCall = poker.expectedValueCall(equity, potBeforeCall, toCall);
const evFold = 0;
console.log({ evCall, profitable: evCall > evFold });

// Breakeven equity for the same spot
const need = poker.breakevenCallEquity(potBeforeCall, toCall);
console.log({ need, hasEdge: equity > need });

Returns number — chip EV of calling: equity × (pot + toCall) − (1 − equity) × toCall when toCall > 0; if toCall ≤ 0, equity × pot.
