Opposition along a diagonal (instead of a rank or file) is called diagonal opposition. Sometimes diagonal opposition is used to achieve direct opposition. An example is the position in the diagram on the left, with Black to move. White has the direct opposition in this position, but it does him no good because his king cannot attack the black pawn after the black king moves away. White needs to achieve direct opposition closer to the pawn.
- 1. ... Kf8
- 2. Kd6 and White has the diagonal opposition (diagram on the right).
- 2. ... Ke8
- 3. Ke6 White now has direct opposition on a useful square, and White wins:
- 3. ... Kf8
- 4. Kd7 Kg8
- 5. Ke7 Kh8
- 6. f6 gxf6
- 7. Kf7 or 7. Kxf6 win for White (Flear 2004:33).

Famous quotes containing the word opposition:
“Commitment, by its nature, frees us from ourselves and, while it stands us in opposition to some, it joins us with others similarly committed. Commitment moves us from the mirror trap of the self absorbed with the self to the freedom of a community of shared values.”
—Michael Lewis (late 20th century)
