premise: The Emami Kolkata Open ATP Challenger Tour (formerly known as State Bank of India ATP Challenger Tour) is a professional tennis tournament played on outdoor hard courts. It is currently part of the Association of Tennis Professionals (ATP) Challenger Tour. It is held annually at the Bengal Tennis Association Stadium in Kolkata, India since 2014.
hypothesis: The Emami Kolkata Open ATP Challenger Tour was held annually at the Bengal Tennis Association Stadium in Kolkata, India until 2014.
reason: The Tour IS held annually at the Stadium since 2014.  I stated that it was held there until then, implying it is no longer held there.  I think the system was fooled because I provided many factual points and only changed a few words making it untrue.
