  Quantum discord has been utilised in order to find quantum advantage in an
extension of the Clauser, Horne, Shimony, and Holt (CHSH) game. By writing the
game explicitly as a Bayesian game, the resulting game is modified such the
payoff's are different, and crucially restrictions are imposed on the
measurements that Alice and Bob can perform. By imposing these restrictions, it
is found that there exists quantum advantage beyond entanglement for a given
quantum state. This is shown by decomposing the expected payoff into a
classical and quantum term. Optimising over the expected payoff, results in the
classical limit being surpassed. This gives an operational framework in order
to witness and determine quantum discord.
