That can be shortened by one move. After 9...Ne8 Chest finds a mate in 4:
Rg3 Nxf6 Qxf6 b5 Rxh7+ Kxh7 Rh3#
c5 Rxh7+ Kxh7 Rh3#
e5 Rxh7+ Kxh7 Rh3#
h5 Rxh5#
h6 Rxh6#
-*- Qxg7#
Nc7 fxg7+ Rxg7 Qxg7#
Nd6 fxg7+ Rxg7 Qxg7#
Rf8 fxg7+ Kg8 gxf8Q#
Nxg7 Qxh7#
Rg4 Qxh7#
Rg5 Qxh7#
Rg6 Qxh7#
Rxg3 Qxh7#
-*- Rxg7 Nxf6 Rxh7+ Nxh7 Qxh7#
Rxg7 fxg7+ =*= Qxh7#
Nxg7 Qxh7#
Rf8 Qxh7#
-*- Rxh7#
Still, the original position is too deep for Chest.
