Thus, finding an efficient representation of an extensive form game is a big challenge for game-playing agents.
AlphaGo  famously used neural networks to represent the outcome of a subtree of Go. While Go and poker are both extensive form games, the key difference between the two is that Go is a perfect information game, while poker is an imperfect information game.
In poker however, the state of the game depends on how the cards are dealt, and only some of the relevant cards are observed by every player.
To illustrate the difference, we look at Figure 2, a simplified game tree for poker. Note that players do not have perfect information and cannot see what cards have been dealt to the other player.
Let's suppose that Player 1 decides to bet. Player 2 sees the bet but does not know what cards player 1 has. In the game tree, this is denoted by the information set , or the dashed line between the two states.
An information set is a collection of game states that a player cannot distinguish between when making decisions, so by definition a player must have the same strategy among states within each information set.
Thus, imperfect information makes a crucial difference in the decision-making process. To decide their next action, player 2 needs to evaluate the possibility of all possible underlying states which means all possible hands of player 1.
Because the player 1 is making decisions as well, if player 2 changes strategy, player 1 may change as well, and player 2 needs to update their beliefs about what player 1 would do.
Heads up means that there are only two players playing against each other, making the game a two-player zero sum game. No-limit means that there are no restrictions on the bets you are allowed to make, meaning that the number of possible actions is enormous.
In contrast, limit poker forces players to bet in fixed increments and was solved in . Nevertheless, it is quite costly and wasteful to construct a new betting strategy for a single-dollar difference in the bet.
Libratus abstracts the game state by grouping the bets and other similar actions using an abstraction called a blueprint. In a blueprint, similar bets are be treated as the same and so are similar card combinations e.
Ace and 6 vs. Ace and 5. The blueprint is orders of magnitude smaller than the possible number of states in a game.

If you played out one of them per second, you'd need 10 billion years to finish them all. That's a lot of game situations.
For No-Limit the number is some orders of magnitude higher since you can bet almost arbitrarily large amounts, but the matter of fact is that the total number of different game situations is finite.
A Nash Equilibrium is a strategy which ensures that the player who is using it will, at the very least, not fare worse than a player using any other strategy.
In layman's terms: Playing the Nash equilibrium strategy means you cannot lose against any other player in the long run.
The existence of those equilibriums was proven by John Nash in and the proof earned him the Nobel Prize in Economics.
This Nash equilibrium means: Guts, reads and intuition don't matter in the end. There is perfect strategy for poker; we just have to find it.
All you need is a suitable computer which can handle quadrillions of different situations, works on millions of billions of terabyte of memory and is blazingly fast.
Then you put a team of sharp, clever humans in front of it, let them develop a method to utilize the computational power and you're there.
Right now Libratus is just the beginning. The AI still simplifies many different poker situations. For example it might not differentiate between a king-jack high flush-draw and a king-ten high flush-draw.
But Libratus is already close to having developed a perfect strategy — at least close enough to annihilate any human counterpart.
Libratus beat humans in No-Limit Heads-Up. Two years ago the University of Alberta introduced Cepheus to the world -- a bot which, for all intents and purposes, plays a perfect Limit Heads-Up strategy.
It's safe to say that those two variants are practically solved. As a matter of fact the guys from the University of Alberta managed to prove that their bot is at worst 0.
Nash equilibrium strategy. While The No-Limit bot Libratus might be much further away from this perfect strategy, it's only a matter of time before it'll be refined and get closer to it.
What about other poker variants? Poker with more than two players is orders of magnitudes more complex than heads-up. The same holds true for more difficult variants like Omaha.
Although we may be okay in online poker vs machines for now if you are however getting the least bit nervous about Libratus and Poker Bots like it, and do not want to invest the small amount required for a HUD, then Switch to Live Poker Tournaments.
Remember that the next time you wonder why you are getting raised and bet off of hands, losing hands on turn and river cards, and not getting max value from your monster hands, its probably because your opponent is like Libratus and knows all about your play from a PokerTracker Best Poker Hud.

Views Read Edit View history.Pitting artificial intelligence (AI) against top human players demonstrates just how far AI has come. Brown and Sandholm built a poker-playing AI called Libratus that decisively beat four leading. While the first program, Claudico, was summarily beaten by human poker players —“one broke-ass robot,” an observer called it — Libratus has triumphed in a series of one-on-one, or heads-up, matches against some of the best online players in the United States. Libratus relies on three main modules. Libratus’ three-pronged approach to the game included: Creating an abstract version of the game which was easier to solve Creating a more detailed plan-of-action based on how the game was playing out Improving on that plan in real time by detecting mistakes in its opponent’s strategy and exploiting. Inside Libratus, the Poker AI That Out-Bluffed the Best Humans For almost three weeks, Dong Kim sat at a casino and played poker against a machine. But Kim wasn't just any poker player. And this. Libratus emerged as the clear victor after playing more than , hands in a heads-up no-limit Texas hold ’em poker tournament back in February. The machine crushed its meatbag opponents by big blinds per game, drawing in $1,, in prize money. Now, a paper published in Science reveals how Libratus was programmed. The approach taken by its creators Noam Brown, a PhD student, and Tuomas Sandholm, a professor of computer science, both at Carnegie Mellon University in the US. Libratus is an artificial intelligence computer program designed to play pokerspecifically heads up no-limit Texas hold 'em.
