del compositor israeli residente en Holanda Yochanan Afek (1952- ), quien es
Gran Maestro (GM) para la composicion en ajedrez de la FIDE (grandmaster for
chess composition since  and International master for over the board chess) y
juez en dicha especialidad. Sin duda una obra bella de jugadas extremadamente
precisas no exentas de la necesaria veta artistica como para haber merecido el
segundo premio del concurso de Schach, publicado en la prestigiosa revista
holandesa "EG" e incluido en el Album FIDE, 2007-2009. Precisamente, en "EG",
Numero 185, Julio de 2011, Supplement, se comenta que es un sacrifico clave la
primer jugada 1.Nd6!! y respecto a la maniobra de reyes y torres dice dice
dicha publicacion: "...Afek developed the move into a tense duel with
classical study elements like a king-rook manoeuvre as well as an original
zugzwang position, that explains the quiet and surprising switch-back 9. Kc5!!
As a bonus there is the typical clearance sacrifice 12.Rb8+! It goes to the
heart of the judge!".} 1-0
