3 dimensiopnal chess

-----------------------------------

I was thinking about making it, but all the rules i've seen so far seem silly, or kinda just made up, so I invented my own, tell me what you think of it:

these are the boolean expressions checking to see if a certain move is valid for a given piece. (note that x is sideways, y is 

forward and backward, z is up or down. z=1 means up, and y=1 means forward, also n means any integer)
(_means absolute value, or magnitude)

(also it's a given that pieces cannot "move" onto their own square)

piece	traditional		3d
pawn	y=1&&x=0		(y=1||z=1)&&x=0
rook	y=0||x=0		(y=0&&x=0)||(y=0&&z=0)||(x=0&&z=0)
bishop	_y=_x			_y=_x=_z
knight	_(_y-_x)=1&&_y+_x=1	_(_y-_x-_z)=1&&_y+_x+_z=1
queen	_y=_x||y=0||z=0		_y=_x=_z||(y=0&&x=0)||(y=0&&z=0)||(x=0&&z=0)||[not sure](_y=_x&&z=0)||(_y=_z&&x=0)||(_x=_z&&y=0)
king 	_y+_x=1||_y=_x=1	y+x+z=1||(_y=_x=1&&z=0)||(_y=_z=1&&x=0)||(_x=_z=1&&y=0)


please note that the pawns move two intial rule means that the have the option of moving a second time.
here also is the valid attack rules
piece	traditional		3d
pawn	y=x=1			y=x=z=1
rook	same as move 		same as move
bishop	same as move		same as move
knight	same as move		same as move
queen	same as move		same as move

king 	same as move		same as move

If you want extra dimensions, Alice Chess http://en.wikipedia.org/wiki/Alice_chess is an interesting variant.
