Do We Detect and Exploit Mixed Strategy Play by Opponents?

We report an experiment in which each subject repeatedly plays a game with a
unique Nash equilibrium in mixed strategies against some computer-implemented mixed strategy. The results indicate subjects are successful at detecting and exploiting
deviations from Nash equilibrium. However, there is heterogeneity in subject behavior
and performance. We present a one variable model of dynamic random belief formation which rationalizes observed heterogeneity and other features of the data.
