Answers.Body: <p>4...Qd2+ in your main line is an error; instead Black should play 4...f4, after which he delivers perpetual check. White can try to play on with 5.Qg5+ Kf8 6.Qxf4 Qxf4 7.c8Q+ but that's still a draw. So 1.Qd8 does not work.</p>

Answers.Text: @Ahmad Azwar Anas Black has already made a mistake in your 1.Qd8 line that includes 6.Kg4; as I said, he should have played 4...f4. So White does not get a chance to play 6.Kh4 instead of 6.Kg4 as you propose.

  4...Qd2+ in your main line is an error; instead Black should play 4...f4, after which he delivers perpetual check. White can try to play on with 5.Qg5+ Kf8 6.Qxf4 Qxf4 7.c8Q+ but that's still a draw. So 1.Qd8 does not work.

  Qd8 is the right idea but allows a pertpetual check after 1... Qf4+. 1. h4 removes all Black's hopes.

  in my Houdini views, you're already win in your normal play, and long way to be draw. `h4` is already the best move.
  
  Black should move `5. ... Qc3` rather than `f4`, `f4` makes Black will lose inmate at maximum 2 possible combination moves.
  
  BUT
  
  rather lose, if I follow your inner moves `Kg4` which give draw to White, in my Houdini views, I saw **Black** absolutely **won**.
  
  as I can say, `Kg4` move is just a curse for White because of force-move check.. ^^
