Joe: Thanks for the elaboration. It clarifies things quite a bit. As for
GO, I am familiar with it and am currently playing a game of it over the
internet. But still, I would not consider the GO stones as chess pieces
any more than I would consider the 'X' and 'O' of tic-tac-toe to be
pieces. The fact that GO pieces work well on a 19 x 19 board has no
signifigance to chess pieces. I am inclined to agree with the opinion
that larger boards can more easily accomodate pieces with greater
mobility... and that multi-move turns are more at home on such boards...
as are larger numbers of different piece types.
