Persecution (chess)

from Wikipedia, the free encyclopedia
This article or the following section is not adequately provided with supporting documents ( e.g. individual evidence ). Information without sufficient evidence could be removed soon. Please help Wikipedia by researching the information and including good evidence.

The persecution is a motif in chess , ongoing in which a character attacks an exposed enemy piece and can not run away right in front of them. This motif occurs in the endgame , but sometimes also in the middle game. A special form of pursuit is perpetual chess , for example in the queens endgame . In the following examples the king is the chasing piece, but any other piece can act as the chasing piece.

4. Kb7-c7 Td8-d5
5. Kc7-c6 Rd5-a5
