As I have played for a long time OTB with a 3D board, I best see 3 dimensions. ... And yes today I can resolve a number of chess problems on a 2D board and still use the 3D board when I need to.
I suspect that boken88 had a "3D" electronic graphical representation of a chessboard in mind rather than a physical chessboard.
I use a "3D" chessboard in ChessMaster. The main problem I have is that it is difficult to find a single viewing angle in which no small pieces are hidden by larger pieces. I find that I have to periodically rotate the board by a few degrees as the board position changes.
personally I really dislike this fancy 3d graphics, it actually messes me up. I prefer the flat view from the top 2d simple is best style
how do you all feel about this?
