Help with "mouseClicked()"

To achieve the following:
if clicked and not flipped, flip;
if clicked and flipped, select; and
if selected and keystroke found, move;
Use the following:
I added 'isFlipped = true;' to show you this needs to be done (it can and should be in the 'flip()' method). You may also want to add 'ChessWorld.lastChessClicked = null;' with it, to de-select last possible mover when something else is clicked on.
String myKey = Greenfoot.getKey();
if (this.equals(ChessWorld.lastChessClicked) && myKey != null)
{
if ("up".equals(myKey) && getY() > 0) moveUp();
if ("down".equals(myKey) && getY() < 7) moveDown();
if ("left".equals(myKey) && getX() > 0) moveLeft();
if ("right".equals(myKey) && getX() < 7) moveRight();
}
if (Greenfoot.mouseClicked(this))
{
if (isFlipped)
{
ChessWorld.lastChessClicked = this;
}
else
{
flip();
isFlipped = true;
}
