GTO Poker

In poker, you might have heard the term “GTO” quite a bit lately. Today we’ll break it down to understand what it really means and how it applies to the game. This article aims to explain GTO, its use in gameplay, and strategies for playing GTO poker, suitable for both beginners and more experienced players! For those looking to put their newfound knowledge into practice, BLITZPOKER offers an exciting platform to test your skills and compete against players from around the country.

What is GTO Poker?

Playing poker optimally, known as Game-Theory Optimal (GTO), involves striving for perfection in your own play. This strategy relies on forcing your opponents into making mistakes, which is where most of your profits come from. It includes using bluffs or semi-bluffs alongside your value bets, determining appropriate bet sizes, and other techniques.

GTO (Game Theory Optimal) poker strategy, which stands in stark contrast to the exploitative approach involves identifying weaknesses in opponents’ playstyles and exploiting them to gain an advantage. On the other hand, the GTO strategy aims for perfect balance, shielding the player from exploitation while capitalising on opponents’ imperfect decisions.

When employing GTO strategy, players engage in a mix of bluffing and value betting across all streets and hands, irrespective of their opponent’s actions. Initially, this might seem counterintuitive, but GTO has proven its effectiveness, especially when we talk about heads-up poker.

To grasp GTO strategy fully, we’ll begin with understanding various game theory concepts. These concepts serve as the foundation for effective implementation and can significantly enhance your poker gameplay.

Why Do Frequencies Matter?

When playing poker, many players simplify their decisions. They’re only thinking about calling or folding, without taking all the factors into account. As humans, we’re influenced by biases. In poker, we often base decisions on observations of opponents and other intangible factors.

In contrast, poker solvers (fancy poker AI), computer programs for GTO poker strategy, take a methodical, mathematical approach. From pre-flop, solvers advise raising certain hands with consistent frequency, regardless of opponents. For instance, a solver might suggest 3-betting certain hands 70% of the time and folding them the other 30% when facing a raise pre-flop. Solvers maintain this approach as they analyze hands on later streets, guiding players to divide their ranges in balanced, unexploitable ways.

Adopting a GTO poker strategy means focusing less on short-term outcomes and sometimes making decisions based on randomness, like a coin flip or a computer-generated number.

Minimum Defense Frequency

While you can’t precisely calculate and apply Minimum Defense Frequency (MDF) during a game, it’s a handy concept to grasp when studying GTO poker strategies away from the table.

MDF simply means the smallest proportion of hands in your range that you should continue with to prevent opponents from exploiting your gameplay.

When you’re employing GTO tactics in poker, your hand range starts with a certain set of hands, which narrows down with each new round and every decision you make. Depending on how much your opponent bets, MDF guides you on the number of hands you should stick with. Naturally, the larger the bet, the fewer hands you should persist with.

You might have witnessed some young players making unconventional calls against small bets on TV. This is because they were applying the MDF principle. Likewise, you may have observed players folding strong hands when faced with hefty overbets. They do this because they recognize they should only call a tiny fraction of their overall range as per MDF.

Every time you face a bet, it’s important to assess how many combinations you have, calculate your MDF, and adjust your decisions accordingly.

To find your MDF, use this simple formula:

MDF = Pot Size / (Pot Size + Bet Size)

Here’s a handy table to help you quickly determine your MDF for various common bet sizes:

100% OF THE POT 50%
75% OF THE POT 57%
66% OF THE POT 60%
50% OF THE POT 67%
33% OF THE POT 75%

So, when you figure out how many hands you should fold to a bet, you then have to decide which hand combos to remove from your range.

Naturally, you’ll want to stick with the hands that give you the best chance in future rounds while dropping those that won’t improve much or won’t match up well against what your opponent might have.

Using a solver can guide you in making these choices, and practising such scenarios with solvers when you’re not actually playing is one of the most effective ways to get ready for real situations when they come up.

GTO Poker and Balanced Ranges

In poker, skilled players no longer focus solely on individual hands. Instead, they consider the range of possible hands they or their opponents could have. This includes what hands they could genuinely possess or what hands they could make their opponents believe they have.

So, what exactly are hand ranges?

A hand range represents all the possible hands that either you or your opponent could hold in a given situation. It’s crucial to try and narrow down your opponent’s range by observing their patterns of play. Some opponents have predictable strategies, making it easier to guess their precise hand.

How much time does it take to grasp an opponent’s range?

There isn’t a specific timeframe for understanding an opponent’s range, but observing about a hundred hands can provide a good insight. Start by analysing how many hands they play from each position and gradually evaluate their preflop actions.

What defines a balanced range?

A balanced range consists of hands that prevent opponents from exploiting your strategy. For instance, if you consistently raise only with strong pairs and AK, opponents can easily predict your actions. Take “Harry,” for example, who only raises under the gun with premium hands or AK. If Harry checks after the flop, it’s clear he doesn’t have a pair but likely has AK.

To avoid predictability and exploitation, it’s essential to balance your betting range. This means mixing up your actions with both strong hands and bluffs. By doing so, you keep your opponents guessing and maintain the strength of your checking range postflop.

The Importance of GTO Poker

Let’s now understand why learning about GTO poker can help you level up your game strategy.

First off, let’s talk about how getting better at GTO poker can help you spot opportunities to outsmart your opponents. Even when you’re following game theory optimal strategies, there are moments where differences in the range of hands each player has can lead to some pretty bold moves. Here are a few classic examples:

  • Going all-in with big bets when your opponent’s hand range is limited.
  • Making strategic bluffs with hands that might not seem strong against an opponent who’s playing defensively.
  • Choosing to fold hands that could catch a bluff when your opponent isn’t bluffing enough based on their betting pattern.

When you understand what your opponent’s hand range should typically look like, notice how they’ve changed it up, and know how a solver deals with similar situations, you’ve got all you need to come up with clever strategies to outmanoeuvre your opponents who aren’t playing as smart.

Mixed Strategy in GTO Poker

Mixed strategy means playing your hand differently in different poker games. This stops your opponents from easily knowing what you’re up to.

What’s mixed strategy?

When you use mixed strategy in poker, you need to be ready to do things that aren’t always the best. For example, if someone raises and you have a so-so hand, you should sometimes raise back, sometimes just call, and sometimes fold. Doing this makes it hard for your opponent to figure out what cards you have and makes you trickier to play against.

How do you make a mixed strategy?

You work out your mixed strategy when you’re not playing. It’s too complicated to decide during a game. This is even more important in online games because you can’t see people’s reactions.

How do you decide randomly in mixed strategy?

There are different ways to mix up your strategy. One way is to use your watch. If you need to do something half the time and something else the other half, you can use the clock face on your watch like a pie chart. This way, your opponent can’t guess what you’ll do. You can also use the suits and numbers of the cards to decide. Or you can go by gut feeling. For example, if you’ve already checked twice in a 50:50 situation, then maybe it’s time to bet. Remember, you should mix up your strong hands too, so your opponents don’t catch on.

Your opponents need to think you might have a really good hand, or they’ll take advantage of you. If they know you probably only have a weak hand, they’ll bet big, and you’ll lose money. To stop this, sometimes you should pretend you don’t have a strong hand when you do.

To play with a mixed strategy, it’s important to make your opponents worry when you check. If they think you might have a strong hand even when you check, they won’t be able to beat you as easily.

How long does it take to get good at mixed strategy?

It takes time to get good at mixed strategy. Beginners should play it safe and slowly change how they play, so they don’t lose lots of money. Mixed strategy can make things harder, so only add it to your game when you’re comfortable.

Understanding Pre-Flop Strategy with GTO Poker Technique

GTO poker strategy focuses on equilibrium, starting with pre-flop decisions. Whether it’s a 6-max cash game or a tournament, poker solvers can advise on the hands to play from different positions.

Similar to conventional poker wisdom, solvers suggest a conservative approach from early positions and a more aggressive one from late positions, but the hand ranges differ.

While some players suggest playing only strong hands from UTG, solvers recommend including all suited aces and hands like QTs and KQ in a 6-max cash game. This emphasis on balance is crucial.

By incorporating these hands, you prevent opponents from exploiting your predictable play with only premium hands from certain positions.

Likewise, you’ll introduce new value and bluffing opportunities in each position, ensuring a well-rounded range that’s difficult to exploit.

Regardless of whether players behind you fold, call, or raise, your range remains balanced, providing effective responses to each action. However, understanding how to play each hand is key.

Thankfully, poker solvers have the capability of providing solutions for various pre-flop scenarios, allowing players to prepare charts for every situation.

Is GTO Strategy Always the Way to Go?

Daniel Negreanu, one of the world’s best poker players, suggests starting with GTO poker but says it’s smart to switch it up to take advantage of your opponents. The trick is to make subtle changes to exploit their weaknesses without giving away your overall strategy.

To make the most profit, you’ve got to blend GTO with exploiting your opponents. But keep in mind, playing strictly by GTO rules isn’t necessary when facing weaker opponents. Since they often slip up, your focus has to be on adjusting your strategy to target their mistakes rather than playing defensively.
