    "abstract": "Three arguments based on the Greenberger-Horne-Zeilinger (GHZ) proof of the\nnonexistence of local hidden variables are presented. The first is a\ndescription of a simple game which a team that uses the GHZ method will always\nwin. The second uses counterfactuals in an attempt to show that quantum theory\nis nonlocal in a stronger sense than is implied by the nonexistence of local\nhidden variables and the third describes peculiar features of time-symmetrized\ncounterfactuals in quantum theory.",
