WebNash equilibrium in large zero-sum imperfect-information games. CFR is an it-erative algorithm that repeatedly traverses the game tree, updating regrets at each information set. We introduce an improvement to CFR that prunes any path of play in the tree, and its descendants, that has negative regret. It revisits that sequence
