Babson Task



 A Babson task is a direct-mate chess problem with the following properties:

   1.  White has only one key, or first move, that forces checkmate in the stipulated number of moves.

   2.   Black's defenses include the promotion of a certain pawn to a queen, rook, bishop, or knight. (Black may have other defenses as well.)

   3.  If Black promotes, then White must promote a pawn to the same piece to which Black promoted in order to complete the solution.

Combining 4 promotions from black with 4 echo promotions from white was the Holy Grail of chess for over a century. The greatest composers failed to compose this task. Then there was a 26 year old soccer trainer from Russia, who realized the impossible: Leonid Yarosh (source: De man die de Babson Task wilde maken - Tim Krabbé)
