How To Calculate Odds?

Here is a step-by-step guide about calculating poker odds and creating a winning hand using it.

Step 1: An overview of what the odds are

Before learning how to calculate odds, you must understand what odds are with an example. If the odds are stacked as 8:1, then you can win one game for every 8 games you play. Another thing to note here is that this also means that you will win eight times the money you paid initially.

Therefore, a safer bet or odds for you would be 4:1 rather than 40:1, even though you will earn much more money in the latter situation. It would be best if you were good at weighing the risks involved and making the moves accordingly. To make better moves, many players carry a poker odds chart with them to make better predictions, but you can do it on your own with good practice.

Step 2: Calculating the odds of winning cards for your hand

It is important to ensure you know how to calculate the poker odds of the cards that will be dealt to make your hand a winning one. To do this, you need to know the number of cards that have the potential to win you the game, which is currently present in the unseen.

Let us take a simple scenario to help you understand how a poker odds chart or the odds would work. Say, your Hole cards are four and seven of a spade. As a result, if you get three more cards of the same kind (spade), you can make a hand of Flush. The three Community cards right Flushre an Ace of heart, King of spade and 6 of the club.

With such a scenario, you know that 3 cards of the spade are in the open. As a result, there will be 13 - 3 = 10 spade cards in the unseen, which could help you make a Flush. This means you have 10 winning cards or ‘outs’, as in poker.

Step 3: Calculate the total number of unseen cards

This simple calculation will help you understand how to calculate odds in poker. This is very easy to calculate. For example, once the Flop has been played, you have seen 5 cards from the deck, including two Hole cards you possess and three Community cards on the table. This naturally makes it 52 - 5 = 47 cards left to be seen by you.

Step 4: Texas Hold’em odds calculator

Once you are well-versed with the above calculations, the process of how calculating odds becomes quite easy. Now that you know you have 47 unseen cards and 10 winning cards, it is easy to calculate the losing cards at this point in the game. 47 -10 = 37. There are 37 losing cards in the deck. With this, you can calculate the odds of your hand to be 37/10, which is 3.7/10. This is a pretty good hand, enabling you to make a good bet.

As you go deeper into the game, the calculations get a bit more complicated, and you might need a poker odds chart to aid you in some cases. Amateurs can use such a poker odds chart to easily understand how to calculate odds.

How To Know When To Call A Bet?

The essence of learning how to calculate poker odds is knowing when to call a bet and when not to. During a game of poker, you will often have a hand that is not worth the showdown but has the potential to become a good or even the best hand eventually. This is where you need to call or raise intelligently. This is called drawing, and straight and flush draws occur more often than not. Flushy making a call with a draw would not do any good, and that is why you should know how to calculate the odds.

As mentioned above, you must find the frequency of hitting the desired draw. At the point of Flop in Texas Hold’em, the odds of you making a Flush is 3.7/1 if we consider the above example. Therefore, you should not call the bet if you do not get similar pot odds or better. Now, this is the case when you only consider the pot odds.

However, if you consider implied odds, then the game changes. You may make a bet if you believe you will have a better hand at the end of the second round. Since implied odds consider the scenarios that can happen during the rest of the game, the calculations are slightly more advanced. Again, you can use a poker odds chart to get a better hang of this, but this might not help beginners.

It does take time, and you might as well need to use the poker odds chart, but not always. So, how to calculate poker odds quickly in the short period allowed by the online game? There is a shortcut method for calculating odds that do not require you to perform several math problems mentally. This is called the rule of 4 and 2.

In this shortcut method, you must know the outs/winning cards and multiply them by 4 and 2 after playing Flop and Turn, respectively. If we again take the same example used above, you have 10 outs at the end of the Flop. When you multiply 10 by 4, you get the percentage of having a winning hand at the end of the game, which is 40%. Similarly, once the fourth card is dealt after Turn, you need to multiply the outs with 2 to get the odds of having a winning hand at the end, which now stands at 20%.

Remember that it does not give you exact percentages; hence, some purists might say that it is not the best way to learn how to calculate odds. Nonetheless, it does the job for beginners and even mid-level players. Thanks to this, you do not need a poker odds chart to identify the odds.
