Displacement
The displacement is a chess motif from the endgame . When pushed away, a king obstructs his opponent's path and thereby forces him to detour. For example, this can prevent bypassing . The Russian theorist Mark Dworezki uses the term body check for this .

The pawn a7 cannot be held. If he is captured, the black king must appear in the answer move on c7 (or c8) in order to achieve a draw .
The straight line 1. Kf7 – e7? allows bypassing Kb2 – c3 2. Ke7 – d7 Kc3 – d4 3. Kd7 – c7 Kd4 – e5! 4. Kc7 – b7 Ke5 – d6 5. Kb7xa7 Kd6 – c7 draw. The game can be won while at the same time pushing away the opposing king on the way to the pawn, a Réti maneuver , because two goals are pursued at the same time:
- 1. Kf7 – e6! Kb2-c3
- 2. Ke6 – d5! Ilja Maiselis found this winning move. What happened in the game was 2. Ke6 – d6? and Black saved himself with a workaround as indicated above.
- 2.… Kc3 – d3
- 3. Kd5-c6 Kd3-d4
- 4. Kc6-b7 Kd4-c5
- 5. Kb7xa7 Kc5-c6
- 6. Ka7 – b8 and the conversion of the pawn cannot be prevented.
The displacement is by no means only important in pawn endings.

The only way for White to try to win is in 1. Rh1 – h2 + If the black king gives way to the first row, 2. Kg4 – f3 wins! - but with 1.… Ke2 – e3! the black king shows his opponent the cold shoulder. White can only repeat the position or give the rook for the pawn.
Displacement and opposition
It is in the nature of things that the opposition plays an important role in the evacuation, because with it an opposing king can be pushed away from two targets at the same time.

Does White play 1. Ke2 – d2 + here? (analogous to 1. Ke2 – f2 +?), Black holds a draw with 1.… Ke5 – f4 (or Ke5 – d4). Correct is 1. Ke2 – e3! - White creates the opposition, pushes the black king out and puts him under pressure . After 1.… Ke5 – d5 (f5) 2. Ke3 – d3 (f3) White pushes the king away and conquers the pawns, even after 1.… Ke5 – e6 2. Ke3 – e4! both pawns fall.
