In this paper, we announced that heads-up limit Texas hold’em poker is essentially weakly solved. This is the first nontrivial imperfect information game played competitively by humans to be solved. Even still, the reader may ask what is the ultimate significance of solving poker? The breakthroughs behind this result are general algorithmic advances that make game-theoretic reasoning in large-scale models of any sort more tractable.
