Reverse Implied Odds

What Are Reverse Implied Odds?

Reverse implied odds describe the potential to lose additional chips on future streets when you make a strong but second-best hand. While Implied Odds measure extra money you expect to win when you hit your draw, reverse implied odds measure extra money you expect to lose when you hit your draw but are still behind. They represent the hidden cost of completing a hand that looks good but is beaten by a better one.

When Reverse Implied Odds Are Worst

Reverse implied odds are most dangerous in these situations:

• Non-nut flush draws: Completing a flush with the 8-high flush on a three-suited board is risky because higher flushes are possible. You may put in significant money on later streets only to discover your opponent holds the nut flush.
• Low-end straight draws: Holding 5-6 on a 7-8-9 board gives you an open-ended straight draw, but completing with a 10 or a 6 means any opponent with J-10 has a higher straight.
• Dominated top pairs: Calling with K-9 on a K-high board looks appealing, but if your opponent holds K-Q or K-J, you will lose additional bets every time they value bet on later streets.

Practical Example

You hold J-9 of hearts and the flop comes Q-7-3 with two hearts. You have a flush draw, which typically warrants a call. However, consider that your opponent raised preflop from early position and could easily hold A-x of hearts or K-x of hearts. If a heart comes on the turn, you make your flush but could be drawing dead to a higher flush. The money you invest on the turn and river chasing what you think is the winning hand goes straight to your opponent. This is reverse implied odds in action.

Adjusting for Reverse Implied Odds

To account for reverse implied odds, discount your Equity by the percentage of the time you make your hand but still lose. If your flush draw has 9 outs but 2 of those outs make a higher flush for your opponent, your effective outs drop to roughly 7. This adjustment significantly changes your calling profitability.
