Black prevents the white king from reaching a key square

In this example, White would win if his king can get to any of the key squares (marked by the white dots). Black is able to prevent this and draw the game – with or without the move. For example:

1. Kd2 Kd5
2. Ke3 Ke5 (the only move to draw)
3. Kf3 Kf5 (the only move to draw)
4. Kg3 Ke5
5. Kg4 Ke4 (the only move to draw) (Müller & Lamprecht 2007:52).

Famous quotes containing the words protected, passed and/or pawn:

    Free competition exists inside shelters of law, custom, insurance, political approval, and carefully protected status.
    Mason Cooley (b. 1927)

    Because it is in the nature of things that they become extreme, we have passed down from manliness to cruelty. If I had been told when I was 20 that there was a tavern in the town where the brave and the cruel were gathered together, I would have run all the way and I would have gone up to the largest and leatheriest of the denizens and said: “If you truly love me, kill the bartender.”
    Quentin Crisp (b. 1908)

    In ceremonies of the horsemen,
    Even the pawn must hold a grudge.
    Bob Dylan [Robert Allen Zimmerman] (b. 1941)
