X.SH LIMITATIONS
X.LP
XDoesn't handle black to play positions.
X.LP
XOnly recognizes algebraic notation.
X.LP
XIf you press the Pause button during GNU Chess's turn
Xxboard will stop the clocks, but GNU Chess will still make a move.
X.LP
XIf you play out an opening set of moves with "Play From File,"
Xyou must make a move and then select "Machine Black."
