You need to know that you’re behind or ahead to get the true odds on the value of your hand. Thinking about what your opponent(s) range is vital when calculating pot odds. Take advantage of them and exploit your opponent. How many outs did your opponent have to land the full house in the previous street? Did he have the odds to put his money into the pot assuming you’d make your flush? Thinking about how you or your opponent might gain or lose outs through the flop, turn and river are vital to calculating the pot odds on each street as well. How strong your hand is one thing, but with the implied odds of the hand now down to just one bet and another decision, you must recalculate the pot odds. With your opponent potentially holding a full house, you have a whole new set of odds to consider. For example, let’s say you hit your flush draw, but the board pairs and your opponent could have a full house. Understanding that your pot odds can change as the streets go on is a big part of staying profitable in poker.
