Qh5-A5 is not the only mate in 2. Qh5 to G7 will give mate next move, no
matter what black does as well.


 If Bc8 moves:
    1. ... Bb7: 2. Qc4#
    1. ... Bd7: 2. Qc4#
    1. ... Be6: 2. Qa7#
    1. ... Bf5: 2. Qc4#
- If Rd8 moves:
    1. ... Rd7: 2. Qc4#
    1. ... Rd6: 2. Qc4#
    1. ... Rd5: 2. Qc4#
- If Re8 moves:
    1. ... Re7: 2. Qc4#
    1. ... Re6: 2. Qa7#
    1. ... Re5: 2. Qc4#
- And if Bf8 moves:
    1. ... Bc5: 2. Qc4#
    1. ... Bd6: 2. Qc4#
    1. ... Be7: 2. Qc4#
    1. ... Bg7: 2. Qc4#
    1. ... Bh6: 2. Qc4#

Did you mean 1. Qf7? I don't think that is an alternative solution because after 1. ... Kc5, White have no checkmate.

''#6'' means Mate in Six, when that kind of thing was popular. These are the Organ Pipes in one instance. Loyd has hundred of them -- #2, #3, #4, #5, #6 in books and columns, and couple of ''Organ-Pipe'' ones besides this probable originator from year 1859. Ralph Betza recalls Excelsior and the American Indian in the Solution.
