Draws are all about "pot odds". Are the odds of you making your draw greater than the money you will win?

Example: You have the AJ of hearts and the flop is Q 8 3 and two of them are hearts.

If either of the next two cards is a heart you'll have made a flush which is a powerful poker hand. Not only that but you would have the "nut flush", the highest possible flush because you hold the ace of hearts.

You are already dreaming about how to spend all that money you're going to win! But wait.

What are the odds of making your flush with two more cards to come?

There are two hearts in your hand and two on the board, leaving nine hearts in the deck of forty seven unseen cards.
