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.
  
  1.h4 enables White to escape from perpetual check, and wins.

  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.
