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. But a bot like Libratus is still so complex it requires a direct connection to its enormous super computer while playing.
And it still plays remarkably slow. So there's no direct danger of it being used in your local casino or online game.
The scary fact is: Bots don't even have to play a perfect strategy. And they don't have to beat the best players.
To make an impact they just have to beat the average player. And there's bad news on that front: We're there already.
For virtually any poker game there already is a bot that plays better than the average, decent human player.
So while poker in general might not yet be solved in a theoretical sense, it's solved enough for a decent bot to beat a decent player. The same phenomena was visible when computer chess was developed.
In fact the first time a computer reached an ELO rating comparable to a master rank was in -- 16 years before the AI eventually beat the world champion.
The answer is twofold as one has to distinguish between live and online poker. It also has to be noted that the problem the poker industry is facing is not new at all.
The Libratus victory is not the first time bots demonstrated their ability to beat decent human players. The bot didn't take any rake; it simply made money by beating the players.
In online poker decent bots have been around at least eight years now and all reputable sites disallow the usage of the.
Any players caught using them have their winnings confiscated and affected players are reimbursed. So the sensational Libratus victory doesn't change much in regards to the difficulties the industry and game is facing -- except it puts the spotlight on the remarkable advances the poker AI has made over the last two years.
As for live poker, not much will change in the foreseeable future. We won't start seeing players using their smart phones to calculate perfect strategies.
Some professional players will certainly use highly advanced bots to examine and improve their own strategies and become better at the game.
But this is happening nowadays already. It's very likely that live poker will not be substantially affected by bots over the next decades, even.
In the same way millions of people still play chess and eagerly watch the chess world championships, despite not being able to beat the AI, we will still see poker players around a green felt playing for titles, glory and millions of dollars for a long time.
For online poker, on the other hand, things do look a bit bleak. This is considered an exceptionally high winrate in poker and is highly statistically significant.
While Libratus' first application was to play poker, its designers have a much broader mission in mind for the AI. Because of this Sandholm and his colleagues are proposing to apply the system to other, real-world problems as well, including cybersecurity, business negotiations, or medical planning.

Carnegie Mellon University. MIT Technology Review. 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. Libratus solves the blueprint using counterfactual regret minimization CFR , an iterative, linear time algorithm that solves for Nash equilibria in extensive form games.
Libratus uses a Monte Carlo-based variant that samples the game tree to get an approximate return for the subgame rather than enumerating every leaf node of the game tree.
It expands the game tree in real time and solves that subgame, going off the blueprint if the search finds a better action.
Solving the subgame is more difficult than it may appear at first since different subtrees in the game state are not independent in an imperfect information game, preventing the subgame from being solved in isolation.
This decouples the problem and allows one to compute a best strategy for the subgame independently.
In short, this ensures that for any possible situation, the opponent is no better-off reaching the subgame after the new strategy is computed.
Thus, it is guaranteed that the new strategy is no worse than the current strategy. This approach, if implemented naively, while indeed "safe", turns out to be too conservative and prevents the agent from finding better strategies.
