Bristol

A line-piece leaves square X and crosses square Y. Another line-piece moves in the same direction to square Y crossing the square X. According to the purity of aim principle the clearing piece should not have any influence on the subsequent play, the sole purpose of its move should be only to clear the line for the follower.

Alias: Bristol clearance; Bahnung (Ger.).
