white rook c6 to e6
black king has only one move to d4
white bishop take black rook b7 to d5
black king and pawn have no moves available, checkmate
white knight d4 to e6 take black pawn
don't care what black does
white queen e5 to g7, checkmate
better make that first move to be white knight d4 to c6 to block black queen move to check on white king
then don't care what black move is
then white queen e5 to g7 for checkmate
trying again
white queen e5 to d6
black turn
white bishop c3 to b4
black turn
white queen d6 to f8 taking black rook, protected from king by white bishop
may have to change depending on black moves
the only way to force the black king to H8 after the first move is to move the white queen the h8 and sacrifice it. but that doesn't gain anything for white
