Description Nonlocal games are an important part of quantum information processing. Recently there has been an increased interest in generalizing nonlocal games beyond the basic setup by considering games with multiple parties and/or with large alphabet inputs and outputs. We consider another interesting generalization—games with nonuniform inputs. Here we derive a tight upper bound for the classical winning probability for a family of nonlocal games with nonuniform input distribution, known as CHSHq(p), which was introduced recently in the context of relativistic bit-commitment protocols by Chakraborty et al. [Phys. Rev. Lett. 115, 250501 (2015)].
