  I really don’t see too many viable lines for Black with the exposure of his King and the open g file. The fastest win for White appears to be:

  1. Re5 (blocking the pin of the Q and threatening Rxh5 mate)
  ….. fxe5 (or 1…Rxe5)
  2 Qg6+ Kh8
  3. Qh6+ Rh7
  4. Qxf6 Rg7
  5. Qxg7 mate

  or

  1 … Qxe5
  2 dxe5 with too many threats down the g file

  Thanks

  Hi,

  I thought of another variation. This one doesn’t lead to mate. But it puts white in a strong position.

  1. Rxe8 Qxg3+
  2. Rxg3

  and white has 2 rooks for black’s one rook. Other reply for black leads to checkmate

  1. Rxe8 Qxe8
  2. Qg6+ Kh8
  3. Qh6+ Rh7
  4. Qxf6+ Rg7
  5. Qxg7#

  1.Re5 Kh8 (other moves result in the mate pointed out by Tom D)
  2.Rxh5+ Rh7
  3.Rxh7+ Kxh7
  4.f4! (blocking the pin of the queen once more!) and black has only senseless, mate prolonging moves like 4. … Qxf4
  5.Qxf4 e.g. Re5
  6.Qh4+ Rh5
  7.Qxh5#
