  <p>The puzzle is tagged with <a href="/questions/tagged/avoiding-perpetual" class="post-tag" title="show questions tagged &#39;avoiding-perpetual&#39;" rel="tag">avoiding-perpetual</a>, yet I cannot see the perpetual check here. It has been discussed in the comments under the puzzle:</p>
  <blockquote>
  <ul>
  <li>Why not just gxf3 and after Qxg3+, run away with the king to the left board edge and hide between pawns?</li>
  <li>Because he can’t hide. When the king reaches c2, the black queen attacks from e2. When the king is on b3, the queen moves to b5, and perpetual.</li>
  </ul>
  </blockquote>
  <p>However, I do not think this is quite right. b5 is protected by the White queen.  So, where and how is perpetual reached on this board? I would appreciate a hint instead of the full solution. :)</p>

Comments.Text: I don't think there is a perpetual after gxf3 Qxg3+, but then there doesn't need to be as black is safe then. The perpetual meant is probably in the line Kf2 Ne5 Bxe5 Qd2+, as mentioned in another comment.

  I think that Kf2 is actually the winning move for White and the perpetual results after gxf3.
  [FEN "4Q/4p1bk/1p1qp2p/p1p1n2B/4P/2P3B1/PP4P/6K b - - 0 1"]
  
  1... Nf3+ 2. gxf3 Qxg3+
  
  Now the White king can not escape the perpetual even though the Black king is very close to checkmate.
