In Christian Hesse's book The Joy of Chess one reads about a mate-in-3 problem composed by Pál Benkö that stumped Bobby Fischer. Hesse gives the following diagram:



[FEN "8/8/8/4k3/8/8/8/2BQKB2 w - - 0 1"]


On the other hand, on ChessBase a slightly different diagram is given:



[FEN "8/8/8/8/4k3/8/8/2BQKB2 w - - 0 1"]


Curiously, both of these positions are valid three-movers with the same key move! But which one is Benkö's actual composition?

Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of
