A procedure that expands the solution set beyond Nash equilibria cannot be categorized as a refinement alongside weak dominance elimination, which strictly reduces the solution set.

Nash equilibrium(Applied here to the pair of uniform randomizing strategies in the fugitive-pursuer bridge game.): A combination of strategies in which neither player can improve their expected outcome by unilaterally deviating, given the other player's strategy.
Refinement(describing how correlated rationalizability relates to simpler concepts): An improvement or narrowing down of a concept that makes it more precise or adds extra requirements beyond the original version.
Solution set(as used in game theory): The collection of all possible outcomes or strategies that could reasonably happen in a given situation or game.
Weak dominance elimination(as a decision-making process in game theory): A method for figuring out what a rational player should do by repeatedly removing strategies that are almost never better than other options—but not quite as bad as strong dominance.
