{[#]} 1. Qf6 Qa7+ (1... Bxf6 2. Re8#) (1... Qb2 2. Qg7+ Bxg7 3. Re8+ Bf8 4.
Rxf8#) (1... Qa8 $1 {a good defensive try} 2. Qg5+ Kh8 3. Kh1 $3 {and Black is
left without a good move} (3. Rxe5 Qa1+ $11) (3. Qe7 Bd4+ $1 $11)) 2. Kh1 (2.
Kf1 Qa8 3. Qg5+ Kh8 $11 {a critical difference vs the position with the king
on h1 is that Qa6+ will pick up the bishop on h6 in some lines}) 2... Qe3 $1 {
the other main defensive try} (2... Qb8 3. Qg5+ Kh8 4. Bg7+ Bxg7 5. Qxd5 $18)
3. Qh4 (3. Rxe3 $4 Rd1+ $19) (3. Bxe3 Bxf6 $11) 3... Bg3 (3... Qc3 4. Qg5+ Kh8

Re8#) 5. Rxe3 $18 {as Black cannot prevent Re8# and hang onto both his pieces}
