    Great sudoku, took 15+ minutes to solve it logically, spent a lot of time finding the chains

      Haha. Thanks. I am glad you liked it.
      There is only one chain and which needs to be done at the end where it becomes more obvious actually. Maybe you missed some easier steps before. But that's still a good timing if not using guess/bifurcation.
