In this diagram, Black is ahead a rook, a bishop, and a pawn which would normally be a decisive material advantage. But White, to move, can draw by perpetual check:
- 1. Qe8+ Kh7
- 2. Qh5+ Kg8
- 3. Qe8+ etc (Reinfeld 1958:42–43).
The same position will soon repeat for the third time and White can claim a draw by threefold repetition; or the players will agree to a draw.

—G.C. (Georg Christoph)
“In the examples that I here bring in of what I have [read], heard, done or said, I have refrained from daring to alter even the smallest and most indifferent circumstances. My conscience falsifies not an iota; for my knowledge I cannot answer.”
—Michel de Montaigne (15331592)
“No rules exist, and examples are simply life-savers answering the appeals of rules making vain attempts to exist.”
