What is the first use of this piece, now known as the Dabbaba? The piece
that leaps 2 spaces vertically or horizontally? My conjecture is that this
is the original Rook. The reason is that this piece fits naturally with the
Gaja and Asva of Chaturanga, which leap to any space in the 2nd square
perimeter. It also has the missing binding of the complete board of the Asva, 1/2 of the
Mantri, and 1/8 of the Gaja.
