}Texas Hold'em or Pot Limit Omaha equity for 2-4 specific hands on 0-5 community cards, returning win, tie, and total equity percentages per hand. Hold'em enumerates every remaining board runout (no simulation). Omaha (game: "omaha", four-card hands, best two play) is exact on every postflop street and scores a deterministic 200,000-board sample preflop (±0.2 percentage points, same input always reproduces).
| Argument | Type | Description |
|---|---|---|
| game | string | Game type; defaults to "holdem". "omaha" requires exactly 4 cards per hand. |
| board | string | 0-5 community cards, e.g. "9h8h2c". Omit for preflop. |
| hands* | array |

}Decide whether calling a bet is profitable. Returns the pot odds, the equity needed to break even, and — given an out count — the exact chance of hitting and a call/fold verdict. Use this instead of doing the arithmetic: the break-even share is call divided by (pot + bet + call), so a pot-sized bet needs 33.3% and a half-pot bet 25%, and computing it as bet/(pot+bet) overstates both. The chance of hitting is counted exactly over the unseen cards, not approximated by the Rule of 2 and 4, which overstates by nearly 6 points on a 15-out draw. Pair it with analyze_hand, which returns the out count for a hand.
| Argument | Type | Description |
|---|---|---|
| bet* | number | The bet you have to call. |
| pot* | number | Pot size before the bet, in any consistent unit. |
| outs | integer | Cards that complete your hand. Optional — omit to get the price alone, with no verdict. analyze_hand reports this as total_outs. |
| street | string | Required with outs: "flop" when two cards are still to come, "turn" when one is. |
| implied_extra | number | Extra you expect to win on later streets if you hit. Optional, defaults to 0; it lowers the equity required. |
