Queen's Sudoku

With the success of the Queen's Gambit, I've been getting requests for chess puzzles.  I figured it was time to post a Queen's Sudoku.  Each row, column, and three-by-three cage must contain exactly three Queens.  Some Queens are given, and the clues attached reveal the number of other pieces they can attack.  Assume that pieces do not block other pieces from attack for purposes of that calculation.  It makes things much easier for the solver!  The solution can be found below.
