I haven't double checked against the map of FIDE events but guess there are no cross overs
I see Khanty-Mansiysk has been awarded the 2019 World Cup and 2020 Olympiad, from PB meeting
The PB received a proposal from Khanty-Mansiysk to hold a 2016 Women’s Grand Prix, the 2018 Women’s World Championship, the 2019 World Cup and the 2020 Olympiad. This was welcomed by the PB and was approved dependant upon no other bid being received prior to the closing of the Bidding Process. As no other bid has been received in time, the Khanty-Mansiysk proposal has been approved, pending ratification by the GA in Baku.
