Check in poker

We often see players at the tables who check automatically, without considering whether it is profitable in the specific spot. They check because their hand is weak, or because they are afraid to bet, or because they do not know what to do next. As a result, they either leave potential value* on the table, or allow opponents to realise their draws cheaply.

* Value is the hand's worth, that is, its ability to win the pot at showdown without bluffing.

The problem is not the check itself. A check is not a mistake and not a sign of weakness. The mistake is checking without a plan, without understanding why we are doing it and what we are going to do next.

In this article we will break down what a check is in poker, when it is justified, and when it turns into an EV*. loss We will also look at the key tools — check-call, check-raise and check behind — and learn to distinguish a deliberate check from a passive one.

* EV (Expected Value) is the mathematical expectation, the average result of an action over time. Positive EV means the action is profitable in the long run; negative EV means a loss.

What is a check in poker

A check is an action where we pass the turn without betting, but remain in the hand. We do not put chips into the pot, but we do not fold either. Check is available only if nobody has bet before us in the current betting round.

If there has already been a bet before us, we cannot check. In that case we have three options: call, raise or fold. A check is always passing the action, not giving up on the hand.

In live poker, a check is indicated by tapping the table or saying «check». In online poker there is a separate button for this. Pre-flop* checking is available only to the big blind if nobody has raised. Post-flop* all players may check if no bets have been made before them.

* Pre-flop is the first stage of the hand before the community cards come out, when players act only with two hole cards.

* Post-flop is all stages of the hand after the flop: flop, turn and river. On the post-flop, players see the community cards and can assess how their hands connect with the board.

In this article we explained what the flop is and why this betting street is especially important in poker. If you're interested in the topic, go ahead and read on. 

A check is a passive action, but it does not make us weak. In a balanced strategy, the check range must always contain strong hands. Otherwise opponents will take pots uncontested with bluffs, knowing that we never have the nuts*.

* The nuts is the best possible hand on a specific board at a specific point in the hand.

When a check is justified

A check should not be the default action. It needs clear reasons. Let's look at the main situations where checking is better than betting.

1. A weak hand out of position, where it is not profitable to bloat the pot

In this spot we check to see the next card for free or to fold to an opponent's bet. This is not cowardice, it is maths: with a hand that has no equity, aggression makes no sense — especially when we are playing out of position and with a wide range. 

Example hand: 

We have 8♠️ 7♠️ in the big blind. The opponent in early position opens with a raise, we call. We have no flop hit and no draw. We check first. The opponent c-bets. We have no reason to continue — we fold comfortably. 

2. A medium-strength hand out of position

When we have a medium-strength hand, such as second pair on a dry board, betting often makes no sense. We will only get called by stronger hands, while weaker ones will fold. Check allows the opponent to bet with a wider range, and we can call profitably.

Example hand:

We have J♥️ T♥️ in the small blind. The opponent in early position opens with a raise, we call. We have top pair with a middling kicker. We check first. The opponent can bet with many hands weaker than ours — with smaller pairs, straight draws, two overcards. There is no point in taking this spot out of position with a made hand, because the player will continue with all stronger hands — and often will not continue with weaker ones. 

3. Setting up a check-raise

If we have a strong hand or a good draw, and the opponent is aggressive and bets often, a check is a way to apply pressure with the next action: we let him bet first, then we raise. This brings in more money than a direct bet.

Example hand:

We have 5♥️5♠️ in the big blind. The opponent on the button opens with a raise, we call. We have a set. The opponent is aggressive and c-bets* almost always. We check, he bets, we make a check-raise. The pot gets bloated, and the opponent often calls with top pair or overcards. If we had bet ourselves, he might have folded many hands.

* A c-bet is a continuation bet made by the player who showed aggression pre-flop.

We have left more insight into the concept of “c-bet” and how to use this tool in play in this article. Go ahead and read on. 

4. Slowplay with the nuts

Sometimes we intentionally check with a strong hand to induce the opponent to bluff. This works against aggressive players or on textures where the opponent has few hands to call with. Note that slowplaying is more of an exception than the rule, but we will still give an example hand. 

We have A♦️ A♠️ on the cutoff. We opened with a raise, the opponent in the small blind called. We have a set of aces. The opponent is very aggressive and likes to bet when no aggression is shown against him. 

Quite often, after our check, we can get an aggressive action from an opponent who would have folded to our flop bet. It is worth noting that we chose an example in which it is rather difficult for the opponent to improve to hands that will beat us — this factor must always be taken into account when we decide to check in position with a strong hand. 

Check on the flop, turn and river

The role of the check changes depending on the street.

Flop. On the flop, a check is most often defensive. We check with weak hands, medium-strength hands, and a portion of strong hands for balance. The flop is the street where the check range is widest, because there is still little information about hand strength.

Turn. On the turn, a check becomes more significant. A check-raise on the turn is one of the strongest actions in poker. It heavily polarises our range: we either have a very strong hand or a bluff. It is hard for the opponent to continue without a strong combination.

River. On the river, checking the nuts is often a missed value spot. In rare cases we can play this way if we understand that the opponent will turn a bet into a bluff. But the best approach is to follow strategy: with the nuts we bet big, and with a medium-strength hand with which we are willing to check-call, we play exactly that way.

The mistake many players make is checking all three streets without a plan. It turns into a passive line, where we are simply hoping for luck. A check should be part of a strategy, not the absence of one.

Let's look at some check lines with further action: 

1. Check-call

A check-call is a line where we first check and then call the opponent's bet. It is one of the most common actions post-flop, especially out of position.

A check-call is justified when we have a medium-strength hand that does not benefit from betting, but is strong enough to call. For example, second pair or top pair with a weak kicker. If we bet ourselves, the opponent will fold all weak hands and only call with stronger ones. If we check-call, he may bet with a wider range, including bluffs.

Check-call is also used with draws when we have no fold equity. If the opponent does not fold to our bets, there is no point bloating the pot with a drawing hand. We check, call a small bet and hope to complete the draw.

The main drawback of check-call is passivity. We do not put pressure on the opponent, allow him to realise his equity cheaply, and often end up facing a difficult decision on the next street.

2. Check-raise

A check-raise is one of the strongest moves in poker. We check, the opponent bets, and we raise. 

A check-raise solves several tasks. 

• With a strong hand, we bloat the pot and force the opponent to pay more for the right to see the next card. 

• With a draw, we increase fold equity* and often take down the pot without completing. 

• With medium-strength hands, we protect ourselves from frequent c-bets from aggressive opponents.

The best check-raise spots are when we have the nuts or a strong draw, and the opponent is aggressive and bets often. On dry textures, the check-raise is especially effective because the opponent has few hands to continue with. 

3. Check behind

Check behind is a check in position after the opponent has also checked. We are last to act, see that the rival has shown weakness, but we do not bet either.

Why would we check in position if we can bet? There are several reasons.

• Pot control. If we have a medium-strength hand that does not benefit from bloating the pot, check behind allows us to keep the pot small. For example, on the flop we have second pair and the opponent has checked. A bet will force him to fold weak hands and call only with stronger ones. Checking allows us to reach showdown cheaply.

• A free card. If we have a draw and the opponent has checked, we can see the next card for free. Betting in this spot makes no sense because fold equity is low (the opponent has shown weakness, but it is not certain he will fold), and we can complete the draw anyway.

• Slowplay. If we have a very strong hand and the opponent has checked, a check behind may induce him to bet on the next street. But this move only works against aggressive opponents. Against passive players, a check behind with a strong hand is a value leak.

4. Check-fold

A check-fold is a sequence where we first check and then fold our hand to the opponent's bet. This is not a move, but a statement of fact: our hand has no prospects.

A check-fold is justified when we have no equity, no draw, and the opponent bets. We do not want to put money into a hopeless situation. Better to save chips for the next hand.

Typical mistakes when checking

1. Checking out of fear instead of checking by strategy

The player checks because he is afraid to bet, not because it is profitable. As a result, he loses value with strong hands and allows opponents to bluff and take pots that could potentially have been won. 

2. Slowplaying to the river with the nuts

The player checks the flop and turn with a strong hand, hoping the opponent will start bluffing. On the river the opponent checks as well, and the player wins a small pot instead of a big one. Slowplaying works only against aggressive opponents. 

3. Check-call without a plan for the turn and river

The player calls a flop bet without understanding what he will do on the next cards. On the turn he checks again and calls again, and on the river he ends up facing a difficult decision. We always need a plan for the whole hand, not just one street.

4. Check-raise bluff with no outs

The player check-raises with hands that have no potential to improve. If the opponent calls, we have no plan for the later streets. A check-raise with a draw is a semi-bluff. A check-raise with hands without potential is simply a chip leak.
