once again i modyfied my solution … made better use of inheritence and use JPanel instead of JFrame and then added panels to it… now my code does update and move, as i used paintAll(graphics g) … also i think my code looks more simple now, even a real biggener can follow. i also added main methode to Piece.java so that u can test it as a stand alone application, and see if it adds the chess piece 
.
so here it is … peace
