Currently with xboard, if an engine sends a move, xboard immediately hits the clocks and sends the move to the other side, so we can't now properly send a draw offer... On the other hand we can send a draw offer followed by a move. I suppose the draw offer is sent to the opponent first and then the move. I wonder how many engines take that move into account before accepting or declining the draw? Perhaps the "draw" command could have an attached move: draw Nf7+. -Dan.
