Can I ask how you figure out the implied odds for the turn and then the river?

Implied odds are by nature ambiguous and difficult to calculate, but it can be broken down into one simple question: "Are they enough?". You don't need to know the exact amount that villain will pay when you hit your draw, you just need to know whether or not villain will pay at least enough for you to break even after the pot is raked. To do this you do the follwing:

1) Calculate your drawing odds (adjusted for any outs that aren't clean). example (all values rounded for convenience): You (Button) are holding A[img]/images/graemlins/heart.gif[/img] 9[img]/images/graemlins/heart.gif[/img] on a board of 8[img]/images/graemlins/heart.gif[/img] J[img]/images/graemlins/heart.gif[/img] Q[img]/images/graemlins/spade.gif[/img] 3[img]/images/graemlins/club.gif[/img] and your extremely passive villain has bet both the flop and turn meaning that he has 9xTx. Your odds of hitting your flush are 4:1.

2) Calculate your pot odds. example cont.: The pot at the start of the turn is $8 and villain makes a 1/2 pot size bet of $4 giving you 3:1 pot odds ($4 to win $12).

3) Calculate the difference between what the pot is and what it would need to be to call profitably based on pure pot odds alone. example cont.: You need to win another $4 from villain to call profitably which means that villain would have to either make or call a bet of $4 on the river if the flush comes in.

4) Based on what you know of opponent determine whether or not you can actually get this money in the pot. example cont.: You have played with villain a great deal since he is a deep pocketed fish and is on your buddy list. You know that he will check to you if the flush comes in on the river. He will always call a bet of about 1/3 of the pot or less, always fold to a bet of about pot size, and his chances of calling a bet in between those sizes varies based on the size of the bet. The pot will be $16 dollars on the river and a bet of $5.50 will get called enough that you can fell reasonably safe of making your $4 plus at least a $1 profit.
