I use it and turn coordinates off bc they bug me.
But I cannot really recommend it bc you cannot capture pieces on it when you play a position on the diagram in order to set it up. So you have to set it from a blank board each time; it is annoying.
I feel like I'm in real trouble with his knight so advanced, and even if he lets me take it my pawns in e & f are under serious threat. I'm not sure I can avoid losing an exchange or getting pinned in this area :/
