There are positions of mutual zugzwang in the endgame with two knights versus one pawn. In this position, White to move draws but Black to move loses. With Black to move:
- 1... Kh7
- 2. Ne4 d2
- 3. Nf6+ Kh8
- 4. Ne7 (or 4.Nh4) d1=Q
- 5. Ng6#
With White to move, Black draws with correct play. White cannot put Black in zugzwang:
- 1. Kf6 Kh7
- 2. Kf7 Kh8
- 3. Kg6 Kg8
- 4. Ng7 Kf8
- 5. Kf6 Kg8
- 6. Ne6 Kh7! (but not 6...Kh8? because White wins after 7.Kg6!, which puts Black to move)
- 7. Kg5 Kg8
- 8. Kg6 Kh8
and White has no way to force a win (Averbakh & Chekhover 1977:106).

Famous quotes containing the words position of, position and/or mutual:
“From a purely external point of view there is no will; and to find will in any phenomenon requires a certain empathy; we observe a man’s actions and place ourselves partly but not wholly in his position; or we act, and place ourselves partly in the position of an outsider.”
—T.S. (Thomas Stearns)
“The Americans are violently oral.... That’s why in America the mother is all-important and the father has no position at all—isn’t respected in the least. Even the American passion for laxatives can be explained as an oral manifestation. They want to get rid of any unpleasantness taken in through the mouth.”
—W.H. (Wystan Hugh)
“Religion is by no means a proper subject of conversation in mixed company; it should only be treated among a very few people of learning, for mutual instruction. It is too awful and respectable a subject to become a familiar one.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
