Hello Edward, I think you may have your board set up wrong: Attempt #2: 1. Qb1 (threatening Qxh7++) h6 2. Qa1 (threatening Qxg7++) Rg8 (black attempts to protect the g7 pawn) Simpler for Black is: 2... Qxc7 removing the White Rook while maintaining the mate threat on the back rank! Note as well that White has two Pawns along the diagonal from a1 to h8 blocking any attack by his Queen at a1.

Moving the queen to h5 allows black to checkmate white with Re1++. Attempt #2: 1. Qb1 (threatening Qxh7++) h6 2. Qa1 (threatening Qxg7++) Rg8 (black attempts to protect the g7 pawn) 3. Rxh6++ (The g7 pawn cannot take h6, since the white queen pins the g7 pawn to the black king.) 2. -Qe7 (blocking the white rook at Rc7( 3. Rxe7 (white rook takes black queen) Rxe7 (black rook takes white rook) Edward Zolotarevsky
