We can also convert that into a percentage (percentages are typically more intuitive) the result is 28%. If we called would be risking $26 and our reward is $41.5 already in the pot plus our opponents bet of $26. On the river our opponent bets $26 into a $41.5. To take an example of when we are facing a bet on the river when we have A9 of diamonds: We can also use pot odds to determine whether or not we can call a river bet based on how often we expect our opponent to be bluffing. Pot odds will tell you whether is it correct for you to call or fold based on what size our opponent bet and how many cards that will improve our hand. This is particularly useful when in a situation where you're facing a bet with a drawing hand (such as a flush draw). Essentially it is how much you will win vs how much you have to risk – your risk to reward ratio. The odds which are being offered to you when your opponent bets are called pots odds.
