Black to move draws, starting with 1...Rh7+. See Desperado

Ponziani's 1769 manuscript contained the endgame study above. White wins as follows:

1. Kf4 Kg7
2. Kf5 Kh8
3. Kg5

Or Ke6 or Ke5, but not Kf6?? stalemate.

3...Kg7
4. h8=Q+! Kxh8
5. Kf6 Kg8
6. g7 Kh7
7. Kf7 and wins.

Ponziani (1782) also gave an example of an endgame blockade or fortress, in which the inferior side is able to hold a draw despite having only two minor pieces for the queen by hemming in the opposing king. (See Pawnless chess endgames, Queen vs. two minor pieces.)

Famous quotes containing the word studies:

    The conduct of a man, who studies philosophy in this careless manner, is more truly sceptical than that of any one, who feeling in himself an inclination to it, is yet so over-whelm’d with doubts and scruples, as totally to reject it. A true sceptic will be diffident of his philosophical doubts, as well as of his philosophical conviction; and will never refuse any innocent satisfaction, which offers itself, upon account of either of them.
    David Hume (1711–1776)
