Shrink chess:

When a file or row becomes empty as a result of the move, this file or row is removed from the board.

E.g. 1. Sa3 a6 2. Sb5 [Remove 3rd row, so black king is now on e7] a4 [Remove 5th row, so black king is now on e6].

Remarks by JdH:

Although it's not explicitly told in the definition, I assume (at least that's how I always played the game during my college years) that the pieces above or to the right of the row/file to be removed are moved downwards/left.

Alain Brobecker told me that the definition of Shrink chess used for the
composition in The Problemist is different. The intended Shrink Chess definition is:

An *EDGE* file or rank disappears if unoccupied (eg: 1.a4 b5 2.axb5 Nc6 3.Rxa7 Rb8 4.Rb7 a-file disappears).
