Among the chess ideas to which the great player Capablanca gave his serious study and playing, one belongs to the Decimal field of the game. From a theoretical point of view, the three "radical moves" in chess are first, vertical and horizontal moves of the Rook; second, diagonal moves of the Bishop; and third, skew leap movements of the Horse or Knight. The chess Queen can be regarded as being a piece which combines two of
these radical moves namely, the orthogonal (Rook) and the diagonal (Bishop) so that the Queen is really the compound R + B. It is quite logical to have a piece combining the diagonal move and the skew leap, and a piece combining the orthogonal move and the skew leap.
