Counting cards is related to blackjack, not poker. Counting cards is impossible in poker because each hand uses a freshly shuffled single deck. As each card is dealt, you will either add 1, subtract 1, or do nothing based on each card’s value. Step 2: The Running Count Keep A Running Count By Adding Or Subtracting Every Card That You See In Each Shoe. As each card is dealt, we will update our “running count” with the new information we are given.

Did you ever wonder what is all the maths that professional poker players seem to be doing in their head? Well a lot of the time they will be counting outs to see what chance they have of winning.

Learning the basics of counting outs is another step on your journey to becoming a proficient poker player. But first what exactly are poker outs?

An out is any card that will improve your hand to better than that of your opponent. A common example is when you have four hearts in your hand and need the fifth heart to complete the flush (i.e. a flush draw) . If you count the number of hearts left in the deck (13 total minus the 4 in your hand = 9), you know how many outs you have and can work out the probabaility of winning the hand.

So counting outs is just very basic addition and multiplication.

In Hold' em, Omaha, and draw poker there is no such thing as counting. In 7 card stud in may be helpful if you can remember all the cards that have been played. If you know that 4 spades are gone then someone drawing to a spade flush would be less likely to have it. Card counting at poker must therefore mean the same as 'how to count outs,' or in other words, 'how to count cards that you can win with.' Counting outs in poker consists of calculating all the unseen hands, the hands with winning potential and then comparing those groups between each other. So how does counting cards at poker work? Say you're on the turn with a flush draw and you wonder how likely it is.

Another simple example is when you have a flush draw such as A♥ K♥ of hearts on T♥ 7♥ 2♠ – you currently only have Ace high but any heart will give you a flush.

There are 9 hearts in total which will complete your draw however one of those hearts (2♥) may give your opponent a full house.

You can also hit an ace (A♠, A♣, A♦) or king (K♠, K♣, K♦) but these cards aren’t always guaranteed to give you the best hand. Generally speaking, you only count the outs which are sure to give you the best hand.

Counting Outs: The Process

The first question you need to ask yourself when counting outs is ’How many cards in the deck will give me the hand I want? ‘

For example if you have a flush draw you will have 9 outs, if you have a gut shot you will have 4 outs, and with an opened ended straight draw you have 8 outs. A table below summarizes each draw with number of outs.

Now that you know how many outs you have you need to actually use that number There is no point in calculating your outs if we aren’t going to use it in our decision making process.

The easiest way to do this is using the rule of 2 and 4…

The rule of 2 and 4

How To Count Cards Easy

This rule is pretty simple.

To work out your equity or chance of winning when seeing the turn you multiply the number of outs by 2. Thus if we have 9 outs we will multiply that by 2 to get 18% equity.

For example if we are on the turn and want to know our chance of hitting by the river this is the method we would use.

To estimate your equity or chance of winning when on the flop you multiply the number of outs by 4. Again, if we have 9 outs we will multiply that by 4 to get 36% equity. For example if we are on the flop and want to know our chance of hitting by the river.

The rule of 2 and 4 is only an estimation for our equity but it is usually accurate giving our equity to within a percentage point or two.

Part of counting your outs is understanding if you are ahead or behind (and by how much) so it is important to understand your opponent's range. For more information on ranges see thefollowing link.

When we know our equity we can make a decision whether our hand is worth continuing with.

This method is actually pretty accurate, particularly for low numbers of outs. See the table below where I compared equity for each situation using the 2 and 4 method and equilab.

The above table assumes that only the the primary draw goes towards our chances of winning. In reality, you will have slightly more equity than the rule of 2 and 4 suggests as you will often have equity from backdoor draws and overcards.

The overall process for counting outs and calculating equity

1. Determine what hand you have or could potentially have. If you are not sure of the hand rankings make sure you check them out
2. Count how many cards will give you that hand
3. Calculate your equity using the rule of 2 and 4
4. Determine if your hand is worth continuing vs a bet by weighting your equity vs pot odds.

Considerations and additional points when counting outs

Double Counting

One must always be careful not to double count outs. With a big draw such as a straight and flush draw we will have 9 outs to the flush and 8 outs to the straight. However, of the straight draw outs there will be two which also complete the flush; thus we must remove these double counted outs.

As a result we no longer have 17 outs (9 flush + 8 straight), we now have 15 outs (9 flush + 6 straight or 7 flush + 8 straight)

The Double gutter

How To Count Cards In Poker Texas Hold'em

One interesting hand type is the double gutter. A double gutter is as the name suggests a double gut shot.

An example is when you have JT on AQ8 board. Any 9 or K will make you a straight. A double gutter can sometimes be difficult to spot, even for experienced players.

However, that makes them more powerful than other draws, as when you hit your hand it is more disguised. A more disguised hand is more likely to get paid off when you hit.

The Monster Draw

Another interesting hand type is the ‘monster’ draw. These are draws with typically 12 or more outs such as a flush draw + straight draw, or a flush draw plus pair type hand.

These hands have so many outs that it almost never wrong to commit all your chips (given you have a reasonable stack size).

The most powerful of all these hand types is the open ended straight flush draw- J♥T♥ on Q♥9♥5♣.

With this hand, not only do you have a flush and a straight draw but you have two cards which are the absolute nuts – you cannot ever be beaten if you hit the K♥ or the 8♥. The importance of these 2 outs cannot be underestimated.

One issue with monster draws is that the rule and two and four begins to break down- the rule overestimates the equity. Although there will be very few situations where you will be folding a big draw.

All Outs Are Not Equal – Anti-outs

Another aspect we need to take into account is that not all outs are created equal. Outs to the nuts (the strongest hand possible) are always the most sought after type of outs; unfortunately we won’t always have outs to the nuts.

In most cases we will count our flush draw out as a normal out but it can complete a full house for our opponent.

Take for example our opponent has 77 on T♥7♥2♠: we will count the 2♥ as an out when we have a heart flush draw.

However, it will improve our opponent's hand at the same time as ours; unfortunately for us that will be to a full house which beats a flush.

We will lose a lot of money in this example.

A further example of drawing to not nutted outs is the ‘dummy’ or bottom end of the straight. When we have the bottom two cards of a four to a straight, for example 87 on T95 flop, we will be dominated by a hand such as KQ; if a jack hits we will both complete a straight but KQ will have the nut straight, beating our lower straight.

As such, drawing to the upper end of the straight is much more powerful. Although, it is not always possible to avoid drawing to the dummy end of the straight. However, take into account they are less powerful than other straight draws and hence you should be less likely to proceed with them vs betting action.

We can apply a similar thought process to overcard outs: AK on T52 board. If we hit our Ace or King on the turn we may not still have the best hand. Someone may have a set or two pair already or they might make two pair with the card which helps us.

Counting Outs Real Life Example:

How many outs do we have here?

Our opponent has 44 and we have 9♥8♥ on T♥5♣3♥7♠ board.

• We have two overcards to our opponent so that is 3 outs for the 9 and 3 outs for the 8 for a total of 6.
• We have a J and a 6 to complete our straight which is 4 each for a total of 8.
• We also have a flush draw of which there is 13 hearts in total. We have 2 of them hearts, our opponent has one and there are two on the board. That leaves 8 hearts.

That gives a total of 22 outs..

How Do U Count Cards In Poker

However we have double counted some of the outs. The 6♥ and the J♥ are counted in the flush and the straight counts we made.

We should only count them once meaning that we now have a total of 20 outs. Using the rule of 2 and 4, we know that we have approximately 40% equity since we are on the turn.

That means we should be calling almost any sized bet on this turn if we knew our opponent had a pair of 4's on the board.

Conclusion

Counting outs is not the most difficult of tasks a poker player must perform; however but it is one of the most useful. If you know how to count and think about your outs you are well of some of the poker population.

Counting outs allows you to understand how likely you are to win the hand. This allow you to decide whether you want to continue versus a bet or raise and hence make more informed decisions at the poker table.

The more likely to win the hand, the less likely you should be to fold.
