Bet types - The Continuation Bet

Introduction

In this article

  • The purpose of continuation bets
  • The role of position
  • Continuation bets on the turn

When you don't have a pocket pair, you will only hit the flop for a
made hand (pair or better) or a strong draw 1/3 of the time. You
usually won't have a hand you can continue to play on the flop when
your pre-flop raise gets called.

On the other hand, your opponents are in the same situation. Cases in
which no one has a hand worth showing occur relatively often. This is
where being the pre-flop aggressor gives you a decisive advantage: Your
bet/raise before the flop signaled strength to your opponents.

This allows you to represent a strong hand. This can be enough to scare
off opponents with marginal hands like small pocket pairs and weak top
pairs, all of which have you beat. Your opponents are so intimidated by
your pre-flop action that they don't want to stay on their marginal
hands, even though they have the best hand at the moment.

You can win a lot of pots without hitting the flop by continuing your
pre-flop aggression. This bet, which is intended to continue your
pre-flop story and win the pot directly, is called a continuation bet,
or contibet for short.

This article will introduce you to the factors
that determine whether or not a continuation bet will be profitable.
You will learn about the mathematics behind this move and the
conditions that must be met for it to promise success. You will also
learn about delayed continuation bets (when you wait for the turn to
continue your pre-flop aggression) and 2nd barrels (when you make a
second continuation bet on the turn after getting called on the flop).

Hasenbraten explains the basics and shows you how to integrate continuation bets into your game.

The theory

The principle of continuation bets

A continuation bet is a bet made on or after the flop by the player who
raised (or made the last raise) before the flop. The name basically
says it all:

The pre-flop aggressor continues his aggression and bets (with the
intention of winning the hand with this bet) even if he has not
improved.

A bet is a continuation bet when:

  • The bet is being made by the pre-flop
    aggressor, meaning he raised before the flop and has initiative
    (meaning he was also the last player to raise pre-flop).
  • The pre-flop aggressor is allowed to bet on the flop (i.e. his wager is not a raise).
  • The player making the contibet missed the flop, meaning he has neither a made hand nor a strong draw.

As you can see, you place a continuation bet when you are the pre-flop
aggressor and missed the flop, but think you have a good chance at
winning the hand with a bet.

You take advantage of the fact that your opponents usually won't hit a
very good hand on the flop either and use the aggressive image you
created with your pre-flop play to take down the pot with a bluff.

Your show of strength with your pre-flop raise will often intimidate
your opponents enough for a continuation bet to be successful.

The mathematics

As with any bluff, the size of your bet and the probability that you
will win the hand are closely related when it comes to determining the
EV.

EXAMPLE

Party Poker No-Limit Hold'em (NL$50) (10 handed)

Hero ($51.00)
SB ($48.00)

Pre-flop: Hero is CO with
K, A
.
6 folds, Hero raises to $2.00, 1 folds, SB calls $1.75, 1 folds.

Flop: ($4.50) T
, 2, 9
(2 players)
SB checks, Hero?;

All the conditions for a continuation bet are met
in this example. The only question is: How often will you have to win
the pot with your bluff bet for it to be +EV?

SCENARIO A:

You bet $1.50 (1/3 pot) for a chance to win $4.50.
This corresponds to 3:1 pot odds. You would therefore have to win the
hand more than 25% of the time in order to make a profit.

SCENARIO B:

You bet $2.25 (1/2 pot) for a chance to win $4.50. This corresponds to
2:1 pot odds. You would therefore have to win the hand more than 33% of
the time in order to make a profit.

SCENARIO C:

You bet $3 (2/3 pot) for a chance to win $4.50. This corresponds to
1.5:1 pot odds. You would therefore have to win more than 40% of the
time in order to make a profit.

SCENARIO D:

You bet $4.50 (pot size) to win $4.50. This corresponds to 1:1 pot
odds. You would therefore have to win more than 50% of the time in
order to make a profit.

You can see the logic:

The larger your continuation bet, the more often it must be successful for it to be profitable.

Additional outs

It is usually the case, as in this example, that
you still have outs to win the hand even if your continuation bet does
get called.

In this case you have a weak draw with your overcards. You assume you
will be heads up with 4 discounted outs if you do not win the hand with
your contibet. Keep this in mind when making your decision.

Let's look at the possible results assuming you
will win another $10 on average when your opponent calls and you hit
one of your 4 outs:

SCENARIO A:

Your opponent folds to your continuation bet and you win $4.50.

SCENARIO B:

Your opponent calls your continuation bet. The probability of hitting
one of your 3 outs on the turn and win another $10 is app. 8.5%. The
probability of missing and having to fold on the turn and losing $2.25
is app. 91.5%. Your average loss after getting called is: 0.085 * $10 +
0.915 * (-$2.25) = -$1.20875

You can now determine how often your opponent must
fold to your continuation bet in order for this move to be break even
(+/- 0).

0 = P(fold) * $4.5 + (1 – P(fold)) * -$1.20875

The result is: P(fold) = 0.21

In order for your continuation bet to be +EV your
opponent must fold more than 21% of the time. This figure includes the
possibility that you could still hit an out on the turn and have the
best hand.

Of course, this calculation has been heavily reduced. The actual amount
you will win if you hit one of your outs and the number of outs you can
actually count on are, by necessity, rough estimations.

But it does give you an idea of how your outs influence the amount of
fold equity you need to generate with your continuation bet in order
for it to be +EV. You can also take a similar approach with gutshot
draws. In general: The more willing your opponent is to pay, the more
helpful is to have additional outs.

Important factors when applying a continuation bet

As you know, continuation bets are meant to win
the pot directly. The probability of it succeed depends heavily on the
following factors:

  • The board texture - Is your opponent likely to have hit a made hand or a good draw?
  • The board texture - Can you represent a strong made hand?
  • The number of opponents in the hand and how likely they are to call.
The board texture

The board texture is basically defined by the following three factors:

  • The size of the cards
  • Connectedness
  • Suitedness

The bigger the cards, the more connected and the
more suited the board, the more likely it is that your opponent has hit
something and the less likely it is that you will be able to win the
pot with a continuation bet.

EXAMPLE 1:

The flop is Q J T.

This is a very dangerous flop, since your opponent
could have hit it in a number of ways. A two-suited flop with three
relatively high, very connected cards is not very suitable for a
continuation bet.

EXAMPLE 2:

The flop is K 7 2.

Your opponent(s) is much less likely to have hit this flop. A rainbow
flop with a single high card and no connectedness is very suitable for
a continuation bet.

EXAMPLE 3:

The flop is 7 6 3.

Your opponent(s) is not likely to have hit this flop, either. No high
cards, no suited cards. you don't have to worry too much about the
connectedness, either, since all of the cards or so low. There is,
however, another problem to worry about: There isn't much you can
represent other than an overpair.

EXAMPLE 4:

The flop is J J 4.

This isn't a bad flop for a continuation bet, neither suited nor
connected. The two jacks are probably just as scary for your
opponent(s) as for you. But chances are low that your opponent has a
jack, since two are already on the board. Once again, the problem is
what you can represent - not much other than trips or an overpair. A
lot of opponents won't necessarily believe your bet.

EXAMPLE 5:

The flop is A T 5.

Neither suited nor connected and with two cards in the playing zone,
this board is also fairly suitable for a continuation bet. The ace is
just as scary for your opponents as it is for you and you can use it to
represent a strong made hand.

As you have seen, the success of a contibet depends on the board
texture. Not only does the board texture indicate how likely your
opponent is to have hit anything, it also determines what kind of hand
you can represent. All bluffs, including continuation bets, work better
when the story you're telling makes sense.

Opponents: Type and number

The more opponents you are facing on the flop, the
more likely it is that at least one of them has hit something and that
he won't be willing to give up his hand to a simple contibet (this, of
course, is also heavily influenced by the board texture).

When facing a single opponent, contibetting most boards should
certainly be in your standard repertoire. When facing two opponents,
you should only contibet on good boards and, preferably, when in
position. When facing more than two opponents, it is so likely that one
of them will have hit something that you don't need to bother thinking
about making a continuation bet at all.

You should, as always, pay attention to your opponents' play and try to
identify them as players (rock, maniac, TAG, etc.) This will help you
estimate how likely he is to fold weak hands to a contibet or to raise
your contibet.

The opponents will be identified based on their PokerTracker stats in
this article. If you don't have PokerTracker (or a similar program) you
will have to identify your opponents by paying attention to their play
and getting reads.

In general: The more aggressive the opponent, the more often he will go
to the showdown and the less likely it is that you will be able to win
the pot with a continuation bet.

WEAK TIGHT

Weak tight opponents don't play many hands pre-flop and only continue
playing when they hit the flop for a strong hand. These are the best
opponents to target with continuation bets. They fold immediately when
they don't have a strong hand. You can contibet the most dangerous
boards when facing such an opponent. Weak tight players are easily
identified by their stats. They have a low VP$IP, PFR and Went to
Showdown value, and usually a relatively high Post-Flop Aggression
Factor.

TIGHT AGGRESSIVE

These are also decent opponents to target with continuation bets. They
usually only play strong hands after the flop and will often fold to
continuation bets. Tight aggressive opponents are usually pretty
predictable, too. If they've let you take control of the hand in the
pre-flop action, you don't have to worry about running into a strong
starting hand. Just be careful if they don't fold; their play should be
taken very seriously. Tight
aggressive opponents have PokerTracker stats similar to yours.

TIGHT PASSIVE

Tight passive opponents play very few starting hands. When they do
play, they rarely show any aggression, even when they have a very
strong hand. These opponents are also good targets for contibets. If
you do get called, you have to take it as a sign that he has a strong
hand and will usually have to give up yours. Tight passive opponents
can be identified by the following stats: Low VP$IP, PFR, Aggression
and Went to Showdown values.

LOOSE PASSIVE

These opponents play a lot of hands, but rarely show aggression. They
usually go too far with their marginal hands and draws and rarely fold,
as long as they've hit the flop in the least way. Bottom pair is
usually reason enough to call an aggressive opponent's supposed bluff.
Continuation bets will rarely work against these calling stations.
Remember, your opponent(s) must be willing to fold marginal hands like
bottom pair or a gutshot draw if your contibet is to be successful.
This is rarely the case when facing a loose passive opponent. Calling
stations can be identified by the following stats: High VP$IP, low PFR,
high Went to Showdown, and low Aggression Factor values.

LOOSE AGGRESSIVE

Continuation bets promise little success against
loose aggressive opponents, as well. These opponents don't just take
their weak hands and draws too far, they also bluff and semi-bluff with
these hands. What may seem like a no brainer contibet can often lead to
a raise. You should completely refrain from continuation bets and wait
for strong made hands when facing one particular type of loose
aggressive opponent: the maniac. They rarely see continuation bets as a
sign of danger, but rather as an invitation to bluff. Loose aggressive
opponents can be identified by the following stats: High VP$IP, PFR,
Aggression Factor and (usually) Went to Showdown values.

You can estimate how likely you will be able to win the pot with a
contibet in a given situation based on all these factors (number/type
of opponents, board texture). We will look at some practical examples
later, but first we have to finish up with the theory.

Sizing your continuation bets

As we said, when it comes to bluffing (and this
includes continuation bets), it's all about telling a plausible story.
It follows: You have to bet the amount you would bet if you had the
hand you are representing. If, for example, you usually place a pot
sized bet on a draw heavy board, your continuation bet on a draw heavy
board should also be pot size.

Your continuation bets should always be the same size as your regular
value/protection bets would be, somewhere between 1/2 and the full pot
size, depending on the situation at hand.

Of course, this only matters when you are playing
with attentive opponents who are observing the game and taking note of
bet sizes in various situations. This is rarely the case in the low
limits. The opponents you find there rarely pay much attention to what
is going on around them and focus solely on their own cards. These
typical weak opponents think: A big bet means he has a big hand, a
small bet means he has a small hand.

Based on experience, a continuation bet of 1/2-2/3
the pot is a good standard size. This signals that you have a hand you
won't easily give up. It's also not so expensive, which means is
doesn't have to work as often to be +EV.

Position

You have seen how many different factors come
together when it comes to continuation bets. Now it's time to look at a
few examples to see how being in/out of position comes into play.

The following stats provide additional help: VP$IP / PFR / Total Aggression Post-flop / Went To Showdown.

EXAMPLE 1

Party Poker No-Limit Hold'em (NL$50) (10 handed)

PT Stats:
SB – 35.3 / 0.9 / 0.6 / 15.0

Hero ($53.20)
SB ($51.25)

Pre-flop: Hero is MP1 with K, Q.
3 folds, Hero raises to $2.00, 4 folds, SB calls $ 1.75, 1 folds.

Flop: ($4.50) 8, 5, 5 (2 players)
SB checks, Hero?

A classic spot for a continuation bet: A safe
board that is not likely to have helped your opponent, a single loose
passive opponent (he plays a bit tighter post-flop), and a decent
number of additional outs with your overcards. If you had AK instead of
KQs, you could almost value bet, since such a loose opponent will often
have a weaker hand. But your bet remains a continuation bet with the
intent of winning the pot and making an ace high hand fold. A good size
would be roughly 1/2 pot, or $2.50.

EXAMPLE 2

Party Poker No-Limit Hold'em (NL$50) (10 handed)

PT Stats:
SB – 5.3 / 0.7 / 1.6 / 17.1

Hero ($67.70)
SB ($41.25)

Pre-flop: Hero is MP1 with T, T.
3 folds, Hero raises to $2.00, 4 folds, SB calls $ 1.75, 1 folds.

Flop: ($4.50) A, K, Q (2 players)
SB checks, Hero?

In this spot you have every reason not to
contibet. Your pre-flop raise was called by a tight passive opponent
from the blinds. The board is very likely to have helped him and you
are most likely behind. The best option is refraining from a contibet
and taking a free card. You might hit your gutshot on the turn.

EXAMPLE 3

Party Poker No-Limit Hold'em (NL$50) (10 handed)

PT Stats:
UTG - 14.2 / 8.1 / 3.2 / 17.9
BB – 42.3 / 10.8 / 1.2 / 33,9

UTG ($27.22)
Hero ($79.30)
BB ($22.75)

Pre-flop: Hero is MP3 with A, K.
UTG raises to $1.50, 4 folds, Hero raises to $5.00, 3 folds, BB calls $4.50, UTG calls $3.50.

Flop: ($15.25) 9, T, 5 (3 players)
BB checks, UTG checks, Hero?

There are a number of reasons not to contibet in this situation: First
of all, the board is relatively draw heavy and could have helped either
opponent. Secondly, you are facing two opponents, who both called a
pre-flop raise and could easily have a strong hand like a middle pocket
pair. Your contibet would have to be fairly large (at least 2/3 pot) to
represent a believable overpair, which would have you committed against
the BB and almost committed against UTG. You can also expect the loose
aggressive short stack to call/raise with a weak made hand out of sheer
desperation fairly often.

Quite a few reasons not to place a continuation
bet. Your fold equity is very low and betting could lead to a very
uncomfortable situation. You should use your positional advantage to
take a free card.

EXAMPLE 4

Party Poker No-Limit Hold'em (NL$50) (10 handed)

PT Stats:
MP2 - 14.2 / 8.1 / 3.2 / 17.9
MP3 – 17.3 / 10.8 / 1.3 / 19.8

MP2 ($45.45)
MP3 ($55.22)
Hero ($109.30)

Pre-flop: Hero is Button with Q, J.
4 folds, MP2 calls $0.50, MP3 calls $0.50, 1 folds, Hero raises to $3.00, 2 folds, MP2 calls $2.50, MP3 calls $2.50.

Scenario A:

Flop: ($9.75) 5, A, T (3 players)
MP2 checks, MP3 checks, Hero?

In this scenario you are facing two opponents.
This time, however, you aren't expecting either one to have a strong
hand or to have hit the flop. Two tight aggressive opponents who limp /
call pre-flop usually have a speculative drawing hand or a small pair.
The board also gives you the chance to represent top pair. If you do
get called and are behind, you still have four outs for a straight and,
possibly, outs for your overcards. You will also be able to take a free
card on the turn fairly often when you do get called on the flop. Being
in position gives you a distinct advantage.

In this situation you contibet against two opponents. You can make a 1/2-2/3 pot (roughly $6) bet on this relatively dry board.

Scenario B:

Flop: ($9.75) 8, 2, 7 (3 players)
MP2 checks, MP3 checks, Hero?

The same situation but with a different flop. This
flop is much more likely to have helped speculative hands like suited
connectors and small pocket pairs. There isn't much you can represent,
either. You do have overcard outs, but you have to discount heavily,
since there are so many hands you could be fair behind against (two
pair, set); a jack could also complete a straight, and any diamond
could give one of your opponents a flush.

In this situation you have much less fold equity and are more likely to
be behind against better hands. The chances of winning with a bluff are
slim. Checking behind and taking a free card is your best option.

EXAMPLE 5

Party Poker No-Limit Hold'em (NL$50) (10 handed)

PT Stats:
MP2 - 24.2 / 5.1 / 1.2 / 19.9
BB – 27.4 / 10.8 / 2.3 / 22.6

MP2 ($65.50)
BB ($45.22)
Hero ($48.27)

Pre-flop: Hero is Button with A, J.
4 folds, MP2 calls $0.50, 2 folds, Hero raises to $2.50, 1 folds, BB calls $2.00, MP2 calls $2.00.

Flop: ($7.75) Q, Q, 5 (3 players)
BB checks, MP2 checks, Hero?

This board may look pretty scary at first glance, but remember that
it's just as scary for them as it is for you. You will usually win this
pot with a continuation bet, even against two opponents, as long as
neither one has a queen or is slowplaying a big pocket pair. Your
opponents aren't particularly aggressive, so you don't have to worry
too much about a bluff check/raise. This makes contibetting a good
option. Your bet doesn't have to be much more than 1/2 pot to represent
a Q or a big pocket pair. $4 is a good size for this spot.

Out of position

One of the main differences between contibetting in position and
contibetting out of position is the option of taking a free card, which
you don't have when you are out of position. This is why it is
sometimes to better to contibet out of position when you would have
taken a free card if you were in position. Checking out of position is
also an option, since you won't be able to buy any free cards in later
betting rounds if you do contibet out of position.

EXAMPLE 1

Party Poker No-Limit Hold'em (NL$50) (10 handed)

PT Stats:

MP2 – 35.3 / 0.9 / 0.6 / 15.0

Hero ($53.20)
MP2 ($51.25)

Pre-flop: Hero is MP1 with K, Q.
3 folds, Hero raises to $2.00, MP2 calls $ 2.00, 5 folds.

Flop: ($4.75) 8, 5, 5 (2 players)
Hero?

The same situation from the last section. Whether you are in or out of
position doesn't change anything in this example. The board is not
dangerous and your opponent, who doesn't like to call very often,
probably missed. A good spot for a 1/2 pot contibet (something around
$2.50).

EXAMPLE 2

Party Poker No-Limit Hold'em (NL$50) (10 handed)

PT Stats:

Button - 14.2 / 8.1 / 3.2 / 17.9
BB – 17.3 / 10.8 / 1.3 / 19.8

Button ($45.45)
BB ($55.22)
Hero ($109.30)

Pre-flop: Hero is CO with Q, J.
6 folds, Hero raises to $2.00, Button calls $2.00, 1 folds, BB calls $1.50.
Flop: ($6.25) 5, A, T (3 players)
BB checks, Hero?

You would probably make a contibet if you were in position in this
example (see Example 4 in the last section). But you have a distinct
disadvantage in this example: Since you are out of position, you won't
be able to see a free card on the turn if you do contibet. One of your
opponents could have hit the flop given the pre-flop action and you can
expect to see a call, raise or even check/raise fairly often. Poor
position and a flop that is fairly likely to have helped an opponent
are two good reasons not to place a continuation bet.

EXAMPLE 3

Party Poker No-Limit Hold'em (NL$50) (10 handed)

PT Stats:
MP2 - 24.2 / 4.2 / 2.6 / 21.8
Button – 17.3 / 10.8 / 1.3 / 19.8

MP2 ($45.45)
Button ($55.22)
Hero ($109.30)

Pre-flop: Hero is BB with K, Q.
4 folds, MP2 calls $0.50, 2 folds, Button calls $0.50, 1 folds, Hero raises to $3.00, MP2 calls $2.50, Button calls $2.50.

Flop: ($7.75) 5, A, T (3 players)
Hero?

A similar situation again, but this time your hand
has much more strength. Neither opponent showed any strength before the
flop and are likely to have speculative hands, which the flop is not
likely to have helped, given the betting sequence.

You have outs for a gutshot and a backdoor flush draw, and your
overcard outs will also be good fairly often. This is a good spot for
an out of position contibet: Your opponents seem to have weak hands and
you have a number of outs you can hit if you do get called. Your bet
should signal significant strength. 2/3 pot is a good size for
representing top pair. You bet $6.

Delayed continuation bets

A delayed continuation bet is a bet made on the turn, not on the flop.
Sometimes you just check a suspicious flop hoping to get more
information before you are willing to invest in a hairy situation.

A hairy situation can be:

  • Facing two or more opponents on the flop.
  • A very dangerous board.
  • You've developed a poor image by playing very aggressively.
  • Your opponent(s) likes to call or is very aggressive.

A check instead of a contibet from an otherwise aggressive player often
raises suspicion. A lot of players think it's a trap. This often leads
to a check behind, which allows you to a) take a free card, and b)
expect a delayed contibet on the turn to be much more effective. Your
opponent will have shown weakness and will have even worse odds to call
with a drawing hand on the turn than on the flop.

The flip side of the coin is that you allow your opponent to take a
free card, as well. You are also much less likely to see a bluff or
semi-bluff on the turn than on the flop. Semi-bluffs with drawing hands
are particularly rare (and inappropriate), since the odds of hitting an
out by the showdown are much worse than they are on the flop.

A delayed continuation bet can only work against
attentive opponents when you also use this line with strong hands. If
you fail to balance your delayed continuation bets, your opponents will
have an easy read and your move will not be profitable.

Delayed continuation bets rarely work against very
weak and/or inattentive opponents. They think a big bet = big hand,
weak bet = weak hand, check = very weak hand, and will try to bluff you
off your hand if you check on the flop fairly often, which makes this
move more or less useless in the lower limits.

Delayed continuation bets are an instrument used to diffuse a dangerous situation and to keep the pot small.

EXAMPLE 1:

PartyPoker No-Limit Hold'em (NL$400) (6 handed)

PT Stats:
Button – 23.7 / 16.8 / 8.3 / 19.5 (A loose aggressive regular at this limit. He often calls or raises your contibets.)
BB - 35.9 / 5.3 / 1.4 / 27.1 (A weak, loose passive player. He lost
half a buy-in in the last hand calling down top pair with middle pair.)

Hero ($449.25)
Button ($646.75)
BB (218.77)

Pre-flop: Hero is CO with K, J.
2 folds, Hero raises to $14.00, Button calls $14.00, 1 folds, BB calls $10.

Flop: ($44) A, T, 8 (3 players)
BB checks, Hero?

This is a good spot to try a delayed continuation
bet. The button is a strong, attentive opponent who rarely folds to a
single (obvious) contibet, as you have seen in the past.

He will react cautiously to a check on this ace high board, since you
had to give up several hands to him on the turn after contibetting the
flop out of position. The BB is the passive type and you don't expect
him to bet the turn without a strong hand if the BU checks the flop, as
well. You might even get a free card and complete your gutshot. The
board isn't very draw heavy, so you don't have to worry about giving
your opponents a free card.

The hand proceeds as follows:

Scenario A:

Flop: ($44) A, T, 8 (3 players)
BB checks, Hero checks, Button checks.

Turn: ($44) 3 (3 players)
BB checks, Hero?

Neither opponent is signaling any strength. The turn card is a blank
and not likely to have helped either opponent. You can follow through
with your plan and place a 2/3 pot (app. $30) delayed continuation bet.

Scenario B:

Flop: ($44) A, T, 8 (3 players)
BB checks, Hero checks, Button checks.

Turn: ($44) 9 (3 players)
BB bets $40, Hero?

The otherwise so passive BB makes a 1/2 pot bet on the turn. The turn
card itself could have completed two straight draws or two pairs
(98/T9). You have no choice but to fold.

Now, you might think it would have been better to contibet the flop,
but this is not so. Remember what we said about the BU. You also have
to assume the BB hit something on the flop. And your notes say he isn't
likely to fold when he has something. You would have lost even more.

The main reason for not contibetting the flop is your poor position,
sandwiched between two opponents, and out of position against the
aggressive BU. Changing the parameters creates a very different
situation:

CO – 23.7 / 6.8 / 2.3 / 19.5 (A semi-loose passive opponent. No specific reads.)
BB
- 35.9 / 5.3 / 1.4 / 27.1 (A weak, loose passive player. He lost half a

Hero ($449.25)
CO ($646.75)
BB (218.77)

Pre-flop: Hero is Button with K, J.
2 folds, CO calls $4.00, Hero raises to $16.00, 1 folds, BB calls $12, CO calls $12.

Flop: ($50) A, T, 8 (3 players)
BB checks, CO checks, Hero?

The following has changed: The aggressive opponent is now much more
passive. You have position on both opponents and additional outs for a
backdoor flush draw. With these new factors you now have a good spot
for a contibet on the flop. You have much more fold equity against
these two weaker opponents. If you get called, you will often be able
to take a free card on the turn. You have better chances at hitting an
out for a cheap price when you contibet the flop.

As you have seen, delayed continuation bets are strongly oriented on
your opponents and the situation at hand. You also have to be sure that
your check rouses enough suspicion for you to be able to bet the turn.
If your opponents aren't paying enough attention to the game or simply
see your check for what it really is - a sign of weakness - you can't
expect delayed contibets to be profitable.

Keep in mind that delayed continuation bets are
much more effective when you are in position than out of position. This
is because your opponents will have signaled weakness twice before you
can place a delayed continuation bet in position. When you are out of
position, you will have only seen him signal weakness once. You should
generally be more cautious when you are out of position and the same is
true when it comes to continuation bets.

The 2nd barrel

Sometimes it can be profitable to bet again on the turn without having
improved. This type of bluff is called a 2nd barrel, since you have to
fire twice before your opponent is willing to give up his hand.

When an opponent calls your contibet on the flop,
he is saying that he either has a made hand or a strong draw and thinks
he has a good chance at winning the hand. His call could also be an
attempt to float, i.e. he calls your contibet thinking it is a standard
move (and that you don't really have a strong hand) and that he may be
able to win the hand with a bluff on the turn. In both instances your
opponent is convinced that you have a rather weak hand. You're going to
have to look for an advantageous situation if you're going to convince
him of otherwise on the turn.

The factors that determine whether or not a second bluff on the turn is
likely to succeed are the same that determine whether or not a regular
continuation bet is likely to succeed: The board texture, additional
outs, number/type of opponent(s) and your own image. The probability of
winning with a bluff/continuation bet is also determined in the same
manner.

EXAMPLE 1

Party Poker No-Limit Hold'em (NL$200) (5 handed)

PT Stats:
Button – 23.7 / 8.8 / 1.8 / 24.5 (A semi-loose passive opponent. No specific reads.)

Hero ($222.21)
Button ($146.95)

Pre-flop: Hero is MP with A, Q.
1 folds, Hero raises to $7.00, Button calls $7, 2 folds.

Flop: ($17) 2, 8, 6 (2 players)
Hero bets $10, Button calls $10.

Turn: ($37) K (2 players)
Hero?

This is a good spot to bluff again on the turn. Your opponent is
neither too loose, nor too aggressive and he probably didn't have a
strong hand on the flop after having cold called your pre-flop raise.
You are likely facing overcards or a small pocket pair.

If he didn't hit the K (and isn't slowplaying a monster) you can almost
certainly represent top pair with a bet and buy the pot. And if you get
called, you still have a few outs (aces, possibly queens). 2/3 pot
(app. $25) should do the job.

This would correspond to 378:25, or 1.5:1 pot odds. You would have to
win the pot 40% of the time for this move to be +EV, which should be
the case. This is without taking your additional outs and the
possibility of being ahead (against 97, for example) into account, so
the result should be even more positive.

A 2 barrel bluff is a way of continuing a continuation bet, but it is
only effective in suitable situations (like the one above) and when
facing just one opponent. If two or more opponents stay in the hand
after you contibet the flop, you can almost always be certain that one
of them has a strong hand and won't be giving it up to a second bet on
the turn.

Now for a look at an example of when you should not fire a 2nd barrel:

EXAMPLE 2

Party Poker No-Limit Hold'em (NL$200) (5 handed)

PT Stats:

BB – 43.9 / 3.5 / 0.8 / 40.7

Hero ($222.21)
BB ($146.95)

Pre-flop: Hero is MP with A, Q.
1 folds, Hero raises to $7.00, 2 folds, BB calls $5.00.

Flop: ($15) 2, 8, 6 (2 players)
BB checks, Hero bets $10, BB calls $10.

Turn: ($37) J (2 players)
BB checks, Hero?

You can (barely) justify firing a continuation bet on the flop on this
relatively safe board against a calling station, but doing so again on
the turn would only prove futile. Your opponent has indicated that he
hit something on the flop, or that he at least has a small pocket pair
or a drawing hand. Either way, chances are you won't be able to make
him fold.

Checking behind and taking the free card is a
better option. You might hit one of your outs or be able to take your
hand to the showdown against a busted draw or weaker ace without
incurring any further costs. The main reason not to bet again, however,
is your insufficient fold equity.

When a continuation bet becomes a value bet

You will at times, particularly when facing weak opponents, be ahead on the flop without having hit.

EXAMPLE

Hero has A K. Villain has 8 9.

The flop is: Q 7 5.

A classic spot for a continuation bet. Your continuation bet turns even
into a value bet when you get called by an opponent chasing a gutshot
draw. You are a clear favorite on the flop (2:1) based on equity. Of
course, your hand doesn't have the highest playability, so you
shouldn't be too optimistic every time you find yourself in such a
situation, but there is often hidden value in such situations when
facing weak and/or very passive opponents.

This should just be noted on the side. An in depth mathematical look at
this situation would have little to do with our subject of continuation
bets. You should simply see that the border between value bet and
continuation bet can be a bit grey. There can also be value in a
standard continuation bet, especially when facing weak, loose and
passive opponents.

Conclusion

No Limit Hold'em is a game that requires constant
analysis and re-analysis. The same can be said when it comes to
continuation bets. The decisive factors are: the board texture, your
image, your position, your outs, and, as always, the number/type of
opponent(s) and their respective hand ranges.

Estimating your opponents' hand ranges and anticipating how they will
(re)act is very important. You will learn to do this in time as you
gain more and more experience.

If you find yourself in a hairy situation and aren't sure whether or
not you should contibet, take the passive route and take a look back at
the hand at the end of the session (or better yet, post in the Hand
Evaluation Forum). You'll know what to do next time you find yourself
in a similar situation.

And as with any bluff or variation of bluff: Don't over do it. A good
bluff comes unexpected. If you contibet every flop, your opponents will
know what you are doing and have an easier time playing against you.
