White to move and win

Solution:

1. Qe4+ Ka6 2. Rh6+ Rf6 3. Qf5! wins

1. ... Kb8 2. Rh8+ Kc7 3. Rh7 Rf2+ 4. Kc3 Rf3+ 5. Kd4(b4) wins
1. ... Kb6 2. Rh6+ Kc5(a5,b5) 3. Qe5+ Qd5 4. Qc7+ wins

André Chéron, in "Lehr- und Handbuch der Endspiele", considered the study incorrect:
Black would draw with 1. Qe4+ Ka6 2. Rh6+ Rf6 3. Qf5 Rxh6 4. Qxf7 Rc6!=

Computer analysis however has proved the correctness of the study:
after 4...Rc6 White delivers mate in 34 moves.

Famous quotes containing the word composition:

    Viewed freely, the English language is the accretion and growth of every dialect, race, and range of time, and is both the free and compacted composition of all.
    Walt Whitman (1819–1892)

    There was not a grain of poetry in the whole composition of Lord Fawn, and poetry was what her very soul craved;Mpoetry, together with houses, champagne, jewels, and admiration.
    Anthony Trollope (1815–1882)

    When I think of God, when I think of him as existent, and when I believe him to be existent, my idea of him neither increases nor diminishes. But as it is certain there is a great difference betwixt the simple conception of the existence of an object, and the belief of it, and as this difference lies not in the parts or composition of the idea which we conceive; it follows, that it must lie in the manner in which we conceive it.
    David Hume (1711–1776)
