Hello Puzzlers,
Doctor Z is ready to operate. My solution:
1. Qd8+ Kg7 (forced move)
White queen covers rank 8 plus f6 square. White bishop covers g6 plus h7 
squares. Black king has one safe square at g7.
2. Rxg5+ (rook sacrifice) hxg5 (forced move)
Since the black king cannot move, black must take the rook with the pawn.
3. h6+ Kxh6 (forced move)
Since the black king is being checked by the pawn, the black king must take the 
pawn creating room for the white queen.
4. Qh8+ Rh7 (forced move)
The white queen has trapped the black king against the edge of the chessboard. 
Notice that the black pawn g5 prevents the black king's escape.
5. Qxh7++ (checkmate)
The white bishop protects the white queen to checkmate the black king.
All the checks by white prevented black from using its pieces.
