Brasil theme

H#2-3: On the two squares where a white knight could check the black king, it would interfere with the line of guard of a white rook or bishop. Therefore, in each of two phases, White moves the rook or bishop anti-critically, enabling the knight to mate on the critical square. [FIDE Album]

⧖ Introduced by Christopher John Feather (United Kingdom, *1947) in his article in Orbit 6, April 2000.
