Echo (chess)

In chess, an echo is a repetitive twist ( mate , stalemate , motif ). The repetition can be done by mirroring or shifting a group of figures in variants (or other phases such as seduction, refutation, formation of twins, threats) or one after the other. If the color of the standing fields changes in this group of figures, one speaks of a chameleon echo . The term is mainly used in chess composition .

Examples:

• Spit as an echo in variants: Josef Kling , Chess Weekly, 1849
• Diversion as an echo: Alexei Troitsky , 500 endgame studies, 1924
• Matt guidance as an echo in variants: Study by Jacobus Haring , 3rd WCCT 1988
• Echo in seductions: Alexei Sergejewitsch Selesnjow , Schachmaty, 1924
• Chameleon echo between threat and solution: Manfred Zucker , Deutsche Schachblätter, 1969
