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).

Read one Texas Hold'em hand on a 3-5 card board: the made hand (category and label) plus every draw with its out count.

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.
