Zillions also overvalues dramatically the Teleporter in my ABChess. That's
a divergent piece which can move anywhere (outside Xiangqi-like
fortresses) to a space of the opposite color, but captures only as a Wazir
(including into or within a fortress). ZoG makes it worth about 1.5
Queens on an 11x11 board. I figure it for perhaps half that, and that may
still be high.
