What is a Semi-Bluff in Poker? In the game of Texas Hold’em poker a semi-bluff may be a sort of a bluff that the player believes the bluff features a chance of immediate success in winning the poker hand right then and there and/or also has the likelihood chance of drawing to form a significant poker hand to win at the end at showdown.
Ask any poker pro, and they’ll tell you the same thing: The best players out there are usually aggressive players who bluff and semi-bluff and take the initiative, bet frequently, and try to take control of the pot. This is true for different types of poker games, especially Texas Hold’em Poker.
For starters, by betting when you have a big hand, you’ll be able to build the pot; after all, the best players are the ones who know how to maximize their winnings when they have good hands but are able to minimize their losses when their hands are garbage. (A garbage hand is a way to describe that the player is holding one of the worst poker hands possible)
Speaking of maximizing your winnings, the best spot to be in is to have the nuts, the best possible hand given the board, whereas the villain, the other guy in the pot, has the second best hand. In such a scenario, you know that nothing can beat your hand, while the villain is fairly certain that they’ve got you crushed. So, you both ship it, and you come out on top. But, realistically speaking, how often does that happen?
In fact, when playing multi-way pots, how many times do you get the best hand, let alone the stone cold nuts? In fact, in a six-way multi-pot, your aces will get cracked 50 percent of the time.
There’s also another problem: If you only play your good hands, other players will have you on a very tight range, making them fold whenever you’re in the pot. As a result, you won’t be maximizing your value when you have the goods.
So, to balance your poker range, i.e. to make it harder for other players to know whether you have a good hand or not, you need to semi-bluff with some of your weaker hands that have potential. Hell, you should sometimes bluff with just air. This will not only make it harder for your opponents to know whether you have the nuts or just air, but it will also enable you to steal some pots that you wouldn’t have been able to win otherwise.
This is known as fold equity, which is based on the probability that other players will fold to your raises, and this is the second argument for being an aggressive player: You can sometimes win pots by the bluff or semi-bluff due to pure aggression alone.
That being said, it is also important to point out that you shouldn’t bluff with every hand you get; other players will put you on a super-wide range, and all your raises will lose their credibility. Obviously, you’ll get more callers when you have the nuts, but you won’t be able to steal any more pots because any sucker with a medium hand, one pair, for example, will call you, and they’ll win most of the time.
Consequently, bluffing too frequently is just as bad as not bluffing at all. The trick is to find that balance and to know when to bluff.
Learning to be Selectively Aggressive
So, how do you find the correct balance between bluffing and playing the cards you have?
Well, as a great poker player once said, “It depends.”
You see, if you are playing against extremely tight players who will only play their premium hands, then you should bluff a lot to steal plenty of those pots. Alternatively, in the event of playing with very loose players who will call with garbage hands, you should probably tighten up a bit and lower the rate at which you bluff and only semi-bluff when your hand has potential.
After all, you need to remember that what determines whether you should semi-bluff or not is your fold equity, and high fold equity means that your semi-bluff has a higher chance of winning you the pot. So, the tighter your opponents are, the higher your fold equity is.
There are several other factors you need to take into consideration. For one thing, you need to think about your table image, which is how other players perceive you: Being perceived as a maniac will have very different consequences than being perceived as a rock that only plays their value hands.
Another variable that should factor into your calculations is the stack sizes of your opponents. For example, if an opponent’s stack is significantly smaller than the pot, then your opponent is pot committed, which is another way of saying that no matter how bad their hand is, they have to call your raise from a purely mathematical perspective.
Fortunately, as a poker player, you aren’t limited to only playing your value hands or bluffing; there is a third way, a middle way: You can semi-bluff. While a bluff is an attempt to steal a pot because that’s the only way your hand can win, a semi-bluff is a bet or a raise when you have a medium hand that isn’t necessarily the nuts but has the possibility of turning into the nuts after the turn and/or the river.
For example, let’s say you have the king and ten of diamonds, and the flop comes ace of diamonds, queen of hearts, and seven of diamonds. On this particular board, you probably don’t have the best hand, and any other player with an ace automatically beats your hand.
However, your hand does have the possibility of improving to the nut flush, and assuming that no other player has a diamond card in their hand, leaving nine other remaining diamond cards in the deck, you have around a 36 percent chance to get your flush and win the hand.
(Note: if you want to calculate the odds of winning a hand, you can use Phil Gordon’s formula, which you can find in his “Little Green Book”, an excellent introduction for many beginning players that gets them well acquainted with poker rules)
The spot described above is an ideal situation for you to semi-bluff, especially if you have position. On the one hand, you can win the hand right then and there. On the other hand, if someone calls your bet or raise, you can still make the nuts on the turn or the river. So, you have two ways of winning the hand: through fold equity or through your hand’s original equity.
To drive the semi-bluff point further, if you assume that your fold equity is around 30 percent, meaning that your opponent will fold three out of every ten times you raise the pot, your total equity for raising is equal to the hand’s equity plus the fold equity, which comes to a grand total of 66 percent. However, if you choose to just call your opponent’s raises, then you only have a 36 percent chance of eventually winning the hand, which will only happen if the flush comes in.
Aside from flush draws, straight draws are usually good hands to semi-bluff with, particularly open-enders. For instance, if you have the king and ten of diamonds, and the flop comes queen of spades, jack of clubs, and three of hearts, you can make your hand if either an ace or a nine comes on the turn or river. Therefore, with four aces and four nines in the deck, there are eight cards in total that can give you the win, so your hand has an almost 32 percent chance of getting there.
As you can tell, the better chance that you’ll make the draw, the more imperative it is for you to semi-bluff your hand. Ergo, it becomes an easy decision for you to raise if you have both a flush draw and a straight draw, such as would be the case if you had the king and the ten of diamonds, and the flop came queen of diamonds, jack of diamonds, and three of clubs.
In such a scenario, there are 15 cards in the deck that will make your hand, giving you a 60 percent chance of winning. At this point, even though it might not seem like it, your hand is a monster, and any bet you make will be for value.
If raising is such a good idea, why not raise with any hand, not just the drawing ones?
As tempting as it may be to raise the pot with seven-deuce, you really shouldn’t get in the habit of doing so unless you know that you have major fold equity; should you raise garbage hands in too many poker games, you’ll go broker before you know it.
This should make all the more sense when you take into consideration the fact that what makes a semi-bluff so powerful is the combination of the hand’s equity plus the fold equity, and if your hand has almost no value whatsoever, then you are just bluffing in this spot. So, the next time you raise, you need to be clear on whether this is a bluff or a semi-bluff, something you can figure out if you know how strong of a hand you’ve got.
First-time poker players always seem to play their hands; they look at their cards and play according to what they have. Alternatively, seasoned players don’t always play their hands; they try to figure out what their opponents think they have and play accordingly. This is part of the game, where players try to get inside each other’s heads, is an integral part at the higher levels.
For example, if you are up against an opponent who is aware that you semi-bluff often, you can act as if you have a flush draw on the flop, regardless of the cards you actually have. So, if you have unsuited seven-deuce, and the flop comes queen of diamonds, jack of diamonds, and three of clubs, by raising the pot, you are sending your opponent a message that you have two diamond-suited cards in your hand. What’s more, if a third diamond comes on the turn or river, you can comfortably raise, representing a made flush, and it will be very hard for your opponent to call unless they have a strong hand to counter.
Again, at this level of play, it is important to be aware of your table image and to understand what patterns other players have seen you carry out consistently. With this knowledge, you can exploit other players.
However, it is important to offer a word of caution here: Just as you are trying to exploit your opponents, your opponents are looking for ways to exploit you. Therefore, if a villain realizes that your bet is a semi-bluff in a spot, they may re-raise you, making it expensive for you to see the turn and river.
To get an idea about what that would look like, if your opponent makes a pot-sized raise, you need at least a hand with 33 percent chance to win for it to be a profitable call. Hence, if you’re already on the turn waiting for the river card, and you need one of nine cards to make a flush, your current hand equity is around 18 percent, making it a mathematical mistake to call a pot-sized raise.
Theory concerning poker strategy has advanced greatly through the years. At some point, David Sklansky dominated the field with his book “The Theory of Poker,” where he discussed a lot of the ideas discussed here, including hand equity and the semi-bluff.
Nowadays, the poker field is dominated by game theory, where plenty of smart individuals learn how to play game theory optimal poker, which relies less on exploitative play. Nevertheless, the emergence of new ways of thinking about poker doesn’t take away from the importance of trying to read your opponent and thinking of ways to exploit them.
So, what can I do to be a better poker player?
To begin with, you should try soaking in all of the available theory out there, something that is all the more important should you decide to enter poker tournaments. And, when you feel that you are up against opponents that are better than you, you might want to resort to game theory. Conversely, if you find yourself surrounded by weaker players, you should try playing exploitatively.
In either case, you need to learn to be an aggressive player and to know when to bluff and when to semi-bluff. If you take away anything from this entry, let it be this:
Passive players who never raise and just call any raise made to them are dubbed as calling stations, and they are a poker player’s favorite type of fish that dolls out most of the cash during a game. So, rather than being a fish, try being the shark instead. See you at the WSOP!
