this makes a great deal of sense to me - a Bishop would be just as strong as a
Rook in normal chess if it was not limited to squares of only one color.  My
guess is that an Archbishop is only slightly weaker a queen - say 8 : 9 or so.
A Chancellor might even be stronger than a queen in some situations (closed
positions).
