Presuming top rank is first rank---

1-Qf6  threatening Bd5++

if 1-......Rf6 2-Bd5++

if 1-.....Bf6 2-Bd6++

other move like RxR or PxP or KxP by black are also of littje help.

Just move Queen up one square. Whether it is f3/c6 I don't know.

1-Qf3 threat Bd5 mate

if 1-.....Rf3 2-Bd5

if 1-      Bf3 2-Bd3 etc

Sorry for giving coordinates wrong earlier.

Looks like arunchess got it.  Great interference puzzle!

Just move Bishop to D3. Mate in 1 move.

if Bd3, Rxd3.

1. Qxh2 Rxh2

2. Bd3#

then what if rook doesnt take queen?
