> River pot odds + MDF + alpha (bluffer’s needed fold frequency)

## Formulas

- requiredEquity = bet / (pot + 2·bet)
- mdf = pot / (pot + bet)
- alpha = bet / (pot + bet) = 1 − MDF

## Naming trap

Alpha is the **bluffer’s** needed fold frequency. Caller break-even (bluff-catch) equals requiredEquity, not alpha. pot=100 bet=33 → ~19.9% vs ~24.8%.

## When to use

- Spot river sizing math for call / defend / bluff frequency
- Agent needs a shareable URL with JSON output

## When not to use

- Full GTO solver, multi-street trees, or range construction
