has some interesting comments on the relative values of Rooks and other pieces - with the usual Kings on an 8x8 board. Ralph Betza (gnohman) states that the Knight+Dabbabah piece can force mate when the only other pieces on the board are the two Kings. Back before Zillions existed I also studied this (very tricky) piece and concluded that a Knight+Dabbabah piece is indeed sufficient mating material. This piece is one of Betza's 'Augmented Knights' - intended to be equal in value to a Rook. Clearly the Squirrel, which can move anywhere the Knight+Dabbabah can, is a more valuable piece.
