As it might be relevant to this discussion,
I will quote [2006-06-18] Gary Gifford:
Jianying: Thanks for the very important question. Yes, normal chess pieces
can capture Dimension X pieces [on the FIDE board], providing that the
piece making the capture is not 'stuck' by an enemy Spider. I've just
made this issue more clear in the rules. Thanks again.
