    My solution to this quiz: 1. Bxh7+.
    Option 1: if …NxB, 2.Qe4 and any the next 2 move will be mate..
    Option 2: if ..KxB, 2. Qb1+ (black can just delay the mate by blocking its B or N.) 3. Qg3..
    Option 3: if ..Kh8. 2. Qb1…Rg8, 3. Nf7+mate

    1. Qb1 [Also winning is 1. Bxh7+ Nxh7 2. Qe4+-] 1…Rf8 (Black can delay mate by sacrificing material on d3 and e4 but the White queen + Bishop battery is too strong] 2. Bxh7+ Kh8 [2…Nxh7 3. Qg6+ Kh8 4. Qg7#] 3. Qg6 Nh5 [3…Rg8 4. Nf7#] 4. Bxf8 Rxf8 5. Nf7+ Rxf7 6. Qg8#
