Pot Odds & Equity Calculation

🧮 What Are Pot Odds?

Pot odds compare the current pot size to the cost of a call — the fundamental math behind every profitable decision.

Formula: Pot Odds = Cost to Call / (Current Pot + Cost to Call)

💰 Example

| Component | Amount | |-----------|--------| | Current pot | $100 | | Opponent bets | $50 | | Your call | $50 | | Pot odds | 50 / (150 + 50) = 25% |

📊 If your chance of winning > 25%, it's a profitable call.

🎯 The 4-2 Rule (Quick Equity Estimation)

| Street | Formula | Example (9 outs) | |--------|---------|------------------| | Flop → River | Outs × 4 | 9 × 4 = ~36% | | Turn → River | Outs × 2 | 9 × 2 = ~18% |

🃏 Example Hand

You hold A♠ K♠, flop is Q♠ 7♦ 2♠ | Draw | Outs | Count | |------|------|-------| | Flush draw | 9 spades remaining | 🃏🃏🃏🃏🃏🃏🃏🃏🃏 | | Overcards | 3 Aces + 3 Kings | 🅰️🅰️🅰️ 🤴🤴🤴 | | Total | 15 outs | |

📊 Flop equity ≈ 15 × 4 = 60% — you're actually the favorite!

🧠 Implied Odds

Sometimes direct pot odds aren't enough, but future bets you can win make the call profitable.

When to Consider Implied Odds

✅ Deep stacks — both you and opponents have chips behind

✅ Disguised draw — opponents won't see it coming (straight with 65s on 7-8-K)

✅ Aggressive opponent — they'll likely fire again on later streets
