Default **uNL Concept of the week: Week 5, Reverse Implied Odds**

NL is a complex game. We all know this. Sure, you get 2 cards, but the game is far more than just the 2 in your hand and the 5 on the board. For the next few weeks, uNL is going to have a concept of the week thread discussing a certain concept or theory in NL Hold'em.

In this thread you should post HH's showing situations where the concept was applied effectively as well as examples of poor usage of the concept. Also, please debate over various aspects of the concept and it's pro's and con's.

Reverse Implied Odds is one of the most misunderstood yet important concepts in unlimted betting hold them (if you dont get that reference read more BBV). But, what exactly are Reverse Implied Odds

What are Reverse Implied Odds (RIO)?

From Theory of Poker, Pg 59, by David Sklansky

[ QUOTE ]
There are other times you must realize that your odds are not as good as they seem. These situations occur wen you have a medicore hand with little chance of improving, which you think is the best hand at the moment, yet your opponent keeps betting. ...Since he is controlling the betting, he will back off on late rounds if he doesnt have you beat. Thus you are in a position to win the minimum if you have the best hand, and lose the maximum if you have the worst hand.

[/ QUOTE ]

When do RIO exist?
In summary, you are in a RIO situation when you stand to make a little and lose a lot. You arent sure where you exist in the hand, Little chance of improvment, a call may commit you to the hand, and your opponent controls the flow of the hand.

How to recognize than avoid RIO situations
Sometimes, it is hard to avoid and recognize RIO situations immediately. They often stem from a call on an earlier street, usually with a dominated hand. If you see that you will normally be calling rather than betting, that is a good indication you are in a RIO situation. When making decisions on earlier streets, you need to think about whether or not you will be in a RIO situation.

Full Tilt Poker
No Limit Holdem Ring game
Blinds: $.25/$.50
6 players
Converter

Stack sizes:
UTG: $45.55
UTG+1: $20.87
Hero: $65.50
Button: $15.50
SB: $47.75
BB: $35.85

Pre-flop: (6 players) Hero is CO with A [img]/images/graemlins/spade.gif[/img] J [img]/images/graemlins/club.gif[/img]
UTG raises to $2.5, 1 folds, Hero calls $2.5 , 3 folds.

Flop: A [img]/images/graemlins/heart.gif[/img] 7 [img]/images/graemlins/spade.gif[/img] 2 [img]/images/graemlins/club.gif[/img] ($5.50, 2 players)
UTG Bets $4, Hero calls $4.

Here we have the beginnings of a RIO situation. Hero's hand strength is relativily unknown. He called a bet in position with a dominated hand, and saw a flop, and hit. Villain bets and hero just calls.

Turn: 3 [img]/images/graemlins/club.gif[/img]
UTG bets $10, Hero ?

Here is where the real RIO comes in. At this point Hero still has no idea of his relative hand strength, his opponent can still back off on the river if beat, he has little chance of improving and if he does still may be beat, and a call here commits you to the river



Another Example:

Pre-flop: (6 players) Hero is CO with J [img]/images/graemlins/spade.gif[/img] J [img]/images/graemlins/club.gif[/img]
UTG Calls, 2 folds, Hero raises to $2.5 , 2 folds, BB Raises to 8, 1 fold, Hero calls.

It starts.

Flop: 7 [img]/images/graemlins/club.gif[/img] 6 [img]/images/graemlins/heart.gif[/img] 8 [img]/images/graemlins/spade.gif[/img]
BB bets 15, Hero ?

RIO right here too.
