Texas Holdem Poker Heads Up Rules
Once heads up is achieved in a home game or pub poker tournament, the most common questions that I hear is, “who goes first?” “who gets dealt the first card?” or “who has the button?” In fact, the most common time that gameplay rule violations occur at the poker table is when I am down to heads up. This is because the rules for heads to head or one on one play in Texas Hold’em can be a bit confusing.

According to heads up poker rules, the dealer posts the small blind and the other player posts the big blind. The first card is dealt to the player in the Big Blind. The dealer acts first pre-flop and the big blind acts first on the flop, turn, and river. The dealer always goes last on the flop, turn, and river.
Ultimate Texas Hold’em is played with a standard deck of 52 cards. To begin the hand, the dealer places five cards, known as the community cards, face down on the table. Each player and the dealer are dealt two cards. Players look at their cards and make a decision to check or raise the ante bet.
- Aggression is Critical in Heads-Up Poker! Aggression is an important part of any form of poker but with heads-up it's critical. You're in the blinds every hand. If you buy-in for $200 for a $1/$2 heads-up match and fold every hand, you will lose half your stack in just 66 hands.
- Texas Hold'em No-limit and pot-limit games, without exception. In limit games, when there are three or more players involved and all players have not gone all-in, games with two betting rounds (draw or lowball) will allow a bet, plus four raises. In a game which involves three or more betting rounds, the maximum raises allowed are three.
- One of the newest casino table games popping up in casinos across the country is the 'Texas Hold'em Bonus' game. Simply, it pits each player against the dealer in heads-up hands of Texas Hold'em poker. Whoever has the best five-card poker hand at the end, wins.
- Texas Hold'em, Pot-Limit Omaha, and many limit poker games all use a system involving the small blind, big blind, and dealer button, with all other table positions relative to those three spots. The small blind is always seated to the left of the dealer button, and the big blind to the left of the small blind.
Why Does the Dealer Post the Small Blind?
If the blinds were reversed and the player on the button posted the big blind, the rules for order of play would be violated. In Texas Hold’em, the Big Blind is required to act last before the flop. Therefore, by default, the player on the button must post the Small Blind in heads-up play.
Additionally, if the dealer was the big blind and decided to fold, he would be folding his big blind to the small blind; another violation of the basic rules. Some might also argue that this “discounted” price of folding is part of the basic advantage of the button
Why Does the Dealer Go First Before the Flop?
The player on the button acts first for the same reason he posts the small blind, to maintain the correct order of play. Some might argue that acting last before the flop offers a type of position advantage and that the button should have that edge in heads-up. However, the button does not have that type of favor when there are 3 or more players at the table, so why should the rules alter when it’s down to heads up? The button never acts last pre-flop, no matter how many players are at the table.
Why Does the Big Blind Go First After the Flop?
The rules of poker state that the button must always act last after the flop. While this might seem like a departure from the rules, since the small blind does act first after the flop in non-heads-up play, it really isn’t. Indeed, it doesn’t matter what position a player sits in, if the button is involved in the hand, they are required to go first.
What If the Button Open Folds Before the Flop?
When the button folds, he relinquishes the small blind to the player in the big blind, the button moves, and the next hand begins. If the button just calls, the player in the big blind has the option to check back or raise. You may have heard the dealer say “option” to the big blind before.
Are Poker Odds Different in Heads-Up?
No. The math of poker remains exactly the same, no matter how many players are involved in the game. The cool thing is that calculating the odds is simplified since there are never any multi-way pots when you are playing one on one.
Are the Heads up Rules the Same for Cash Games and Tournaments?
Yes, the order of play and the rules for posting blinds remains exactly the same, no matter the format. The only real difference you will see, when watching cash versus tournaments, is that the latter often has antes paid in on top of the blinds.
Are These Rules the Same for Pot Limit Omaha?
Yes, the rules of heads-up play remain the same for all flop-style games that have a button and two blinds, including limit hold’em, no-limit hold’em, and Omaha.
Strategic Adjustments For Heads-Up Play
Once you have the rules of how one on one gameplay works, you can focus all of your attention on winning. The key to crushing the competition is in making targeted adjustments based on your opponent’s style of play.
The biggest adjustment that should be made when playing heads up revolves around how often you raise and call and how assertive you should be when it comes to fighting for pots. As a rule, as tables become more short-handed, your overall level of aggression should increase. When play is down to just you and one other people your level of aggressiveness should range anywhere from combative to downright maniacal. What controls your frequencies in this regard is the nature of your opponent.
In order to thrive in and succeed one-on-one, you have to drastically loosen your requirements for getting involved and continuing into later streets. As the old saying goes, it’s very hard to make a pair. Often, high card will be the best hand on the flop in a heads-up battle. Therefore, you definitely do not want to play fit or fold when there is only one other opponent.
Feel Out Your Opponent Early
The early stages of a heads-up match are very similar to boxing. Unless you are really familiar with how your opponent plays, you will need to feel him or her out in the first few hands. For the most part, my general strategy is to raise any two hands from the button but defend a bit on the tight side in the big blind. By using this method, here are a few things you are looking to find out along with the adjustments that you can make as a result:
Pre-Flop Heads-Up Adjustments
- Your Opponent Is Folding to Steals Often
Count your blessings if this is the case. Playing against a fit or fold opponent when down to two players is the best case scenario. Keep stealing any two cards until he or she adjusts. You may find that you have the majority of the chips before this happens! - Your Opponent Seems to Be Defending Every Time
If you open your first 5 hands and get called or raised 5 times, it may be time to re-evaluate your strategy. Even so, I would almost never reduce my opening frequency down below 50% in a heads up match. - Your Opponent Is Stealing Often
So your opponent has open-raised the first 8 hands or so in the match. It is time to start playing back at him and the best way to do this is to flat call all of your high card hands, even Q2o, and anything that is suited or has any flopability (is that a word)? For example, something like 74o is an easy flat against someone who opens practically any two cards. - Your Opponent Is Folding the Button Often
If your opponent is open-folding the button more than half the time, it is safe to tighten up your flatting and 3-betting range substantially. The free money you are getting from your opponent’s folds means that you are practically free rolling the big blind. How cool is that? Ramp up the aggression on the button and the match will be over soon (usually in your favor).
Post-Flop Heads-Up Strategy
Your opponent’s pre-flop tendencies will tend to bleed over into their post-flop play. Therefore, if a person is stealing wide pre-flop expect them to bluff a lot and take very weak ranges to later streets
Summary
In live games where the players do the dealing, heads up play is the most common part of a tournament that the gameplay rules of poker are violated. More frequently than you might think, either the incorrect person gets dealt to first or the order of play is reversed.
It makes sense that sometimes people forget the heads-up rules since it can be rather rare to make it to heads-up in a tournament. It’s easy to see how the rules can be forgotten when a player might only achieve heads up once every few months. Even so, once the reasons behind why the dealing and playing order are understood, it all makes perfect sense.
Once you have the rules down, I suggest that you spend a few hours practicing at home with a family member. That way the heads up rules will be followed to the tee next time you find yourself as one of the last two players in your next local event. Besides, you should be focusing on adjusting your strategy and beating your opponent, not on who goes first or whatever. Good luck, now go win that thing!
Stripper Stacks
Strippers are cards that are shaped in such a way as to allow them to be easily controlled by pulling them out of the deck, no matter where they are located.
A stripper stack uses this concept, along with carefully chosen cards, to enable a cheat to easily stack the deck in their favour.
A well known example of a stripper stack is the ten-card poker deal, which is a concept often used by magicians.
The Ten-Card Poker Deal
The ten-card poker deal came from the card table; it originally used nine cards and was specifically designed for a 5-card straight poker heads-up scenario.
The cheat would take nine cards from the deck, and cut them in such way that they could be stripped out when required.
In play, after the mark had shuffled, the deck would be passed to the cheat to be cut. The cheat would use the motion of cutting the cards to strip out the nine target cards and place them on top.
The result of this would be that the nine cards are dealt between the two players, with the mark’s final card being a random card from the deck.
The nine cards consisted of three sets of three-of-a-kind, which we will denote A, B, and C.
So the nine cards are: AAABBBCCC. As such there are a relatively small number of possible outcomes:
The table shows the probabilities that either party will win, given the way the nine cards come out, and whether the random card is helpful to the mark or not.
In most cases the random card is not useful, and the cheat will win. But occasionally the random card will improve the marks hand, and in some cases that may be enough to beat the cheat.
Overall, the cheat will win 96.01% of the time, whereas the mark will only win 3.99% of the time.
The advantages of this particular method of cheating, are that
- It only requires a single “cut” type action, which is built into the game’s procedure,
- It’s done on the opponent’s deal,
- It has a very high success rate.
The main disadvantage is that it requires stripped cards, which need to be put into the game somehow.
Getting Strippers into the Game
Cutting cards to make strippers is not generally something that can be done at the table, which leaves three options:
- Making sure the deck in play has already had the cards doctored
- Switching the deck or the required cards during play
- Cutting the cards from the deck in-play
The first method could be achieved by stocking the local shop with a large number of doctored decks and then insisting that a new deck is purchased before the game begins. Another method would be to have an accomplice who pretends to purchase a deck, but in fact just provides a prepared deck.
Alternatively, the deck could be switched before the game; again with an accomplice that has access to where the decks are stored.
A deck switch could also be done by the cheat during the game, either when they handle the cards to deal, or when given the cards for a cut. In some cases an accomplice may be used to provide a distraction whilst the decks are switched.
Depending on the style of strippers used, it may actually be only the target cards that need to be gimmicked. In this case they could be slowly switched out, one at a time, throughout the night as game play continues.
Finally, the cards in play could be cut, which would require stealing them from the deck, taking them somewhere private to put the work in, and then reintroducing them back into the pack.
A Stripper Stack for Heads-Up Texas Hold’em
Currently, the most popular form of poker is Texas Hold’em, which has quite a different format to straight poker.
Two face down hole cards are dealt to each player, then between rounds of betting, five communal cards are dealt face up on to the table. The players must make the best 5-card hand using their hole cards and the communal cards.
The aim would be to find a set of cards that can be stripped to the top in a single cutting action, and provide a high win rate, when playing heads-up Texas Hold’em.
The introduction of communal cards means that in many cases the winning hand is not decided until the final card comes down. This means that, selecting a set of 11 cards, such that the river card is random, makes the final result highly variable. So this is not a particularly effective strategy.
If the rules were loosened slightly to allow two ‘moves’, then 7 cards of one suit could be stripped to the top in the first action, and the ace of that suit stripped to the top in a second action. So, instead of ensuring that the mark is dealt a bad card, it’s ensured that the cheat is dealt a good card. In this case, both players would make a flush, and the cheat would win with the ace. This scenario produces a 100% probability of the cheat winning, as the ace high flush can’t be beaten, regardless of which cards are dealt on the turn or the river. However, there is the risk that the cards the mark ends up with are not good enough for them to want to bet on; so whilst the cheat will still win the hand, it may not be the biggest pot.
An alternative would be only controlling the hole cards, risking the fact that the 5 communal cards could completely change the winning hand.
By stripping three aces to the top on the mark’s deal, the cheat will ensure a pair of aces for themselves and the mark will be dealt at least one ace.
There are two advantages to this; firstly, giving the mark an ace may entice them to stay in the hand longer, giving the cheat the opportunity to win more. Secondly, the cheat holds the other two aces, which makes it unlikely that the mark will pair their ace. Furthermore, if the mark makes a hand with their ace, then in many cases the cheat will at least be able to equal the hand, and in some cases beat it.
To illustrate this advantage, the cheat’s pair of aces against any other two random cards, gives the cheat a win rate of 84.93%, the chances of drawing are 0.54%, and losing is 14.52% [results from wizardofodds.com]. Whereas, when the cheat’s aces are up against an ace and any other card, the cheat’s win rate is increased to 88.67%, the chances of drawing is increased to 3.17%, and crucially the probability of losing is now only 8.15% [results calculated with the help of cardplayer.com]. So by giving the mark an ace, the cheat’s chances of winning are increased, as is the chance of the mark making a bet.
Whilst this 88.67% probability of winning is not as high as 96.01% for the straight poker game, or the 100% for the flush scenario, it is still gives a reasonably high guaranteed edge.
To take this further, in The Mathematics of Poker, by Bill Chen and Jerrod Ankenman, a near optimal strategy is given for heads-up play when both player’s stacks are less than 50 big blinds. This strategy suggests that the only two moves in this scenario should be to jam or fold. The details of this strategy are described by a table, which give all possible hole card combinations, and assigns each a value. For the attacker, this value is the stack size in big blinds at which your play should switch from fold to jam. A second table is given for the defender, which dictates at what stack size their strategy should switch from fold to call.
When heads-up it’s common for the order of play to change. In standard multiway tables the player to the left of the dealer posts the small blind, the next player puts up the big blind, and the next player is the first to act. In this manner when heads-up, the dealer would put in the big blind and their opponent would act first. However, the change in play for heads-up means that the dealer acts first and their opponent puts in the big blind.
As the cheat is stripping the cards on the mark’s deal, then if the special heads-up order of play is enforced, the cheat is considered the defender. Whereas, if this change of play is not introduced, then the cheat would be considered the attacker.
Whilst the jam-fold strategy was developed for the alternate heads-up order of play, with the dealer acting first, results were calculated considering the cheat as both the attacker and the defender.
The following graph shows the cheat’s probability of success for a given opponent’s stack size. Where success would mean that the mark did not fold, and the pocket aces won the hand.
The cheat’s actions are clear, with their aces, they should jam if they are the attacker or call if they are the defender. However, the mark’s actions will depend on their stack size and what random card they get with their ace.
Texas Holdem Poker Heads Up Rules How To Play
The graph shows that the cheat is more likely to succeed if they are the defender, which suggests that the alternate heads-up order of play is beneficial for this method of cheating.
As an example, if the mark has a stack of 40 big blinds, then there is a 60.64% chance of the mark going all-in and the cheat winning the pot.

For a 50% or greater probability of success, the cheat should use this technique when their opponent has less than 42.6 big blinds in their stack. Or 29.2 big blinds if the alternate heads-up order of play is not used and the cheat is the attacker.
Conclusion
Texas Holdem Poker Heads Up Rules Card Game
The nine-card poker deal was designed for a game of straight poker, and gave the cheat a 96.01% chance of winning the pot. The required cards could be stripped out in a single cutting action, meaning that the play would take place on the mark’s deal.
Applying the same methodology to the game of Texas Hold’em is made more difficult with the introduction of communal cards. But by stripping only three aces, a similar outcome can be achieved; although the win rate drops to 88.67%.
Furthermore, using the near-optimal jam-fold strategy when the players are down to less than 50 big blinds, the cheats probability of success can be determined. These results suggest that the cheat has a greater than 50% success rate when their opponent has a stack of 42.6 big blinds or less.
As a final thought, after the mark calls all-in and the cards are flipped over, they will likely realise that they are a severe underdog. This opens up the opportunity for making a deal and potentially dividing up the pot in a cash game, or deciding finishing positions and prize money splits in a tournament. Making a deal negates the risk of running the board and losing, for both players.
