A 3-D chess variant from Texas Educational Devices, 1966, for psychological experiments. Knights move one square diagonally in any direction. I have the fifty move rule kick in if there have been no pawn moves on the same level. Pritchard says nothing about pawn promotion. I let them promote when they reach the opposite side.
