  Queen endings are among the most difficult.
  
  We usually say "win by force" when there's a definite winning line. You're asking if White is certain to win, not at all certain.
  
  A human player would look first to winning the queenside pawn and then with an advantage on both wings, many chances to win. But while that pawn sits on a black square White can't coordinate force against it.
  
  And I don't think White can try for a kingside initiative while the a-pawn has to be tended to. White doesn't want to move it to a5, where it's fixed and can be coordinated against, and it's always exposed to threats on a4.
