Thread: Ratsuk Game

I am trying to make a game named ratsuk that is like chess but only with the knight. The knight cant move were it has moved before. when the player cant no longer move he loses. the problem is that Knights still appear in places it shouldn't so i end up with two or more knights at once. Been running it a lot and i start seeing a pattern. If the knight is at (row,column) a new knight always appears at (row+4,column+2) but its not restricted to this. I cant find out whats wrong.

all the possible movements are not yet implemented. Caballo and acciones are the method giving me trouble.

public void caballo(final int row, final int column) {
 
        final JButton current = mesa[row][column];
 
        current.setIcon(image);
        panel.repaint();
 
        acciones(row, column, current);
    }
 
    private void acciones(final int row, final int column, final JButton current) {
 
        final int nextRow = row + 2;
        final int nextColumn = column - 1;
        if (tienebotton(nextRow, nextColumn)) {
            JButton next = mesa[nextRow][nextColumn];
 
            next.addActionListener(new ActionListener() {
                public void actionPerformed(ActionEvent e) {
                    current.setIcon(null);
                    caballo(nextRow, nextColumn);
                    ((AbstractButton) e.getSource()).setEnabled(false);
 
                }
            });
        }
        final int nextColumn1 = column + 1;
        if (tienebotton(nextRow, nextColumn1)) {
            JButton next1 = mesa[nextRow][nextColumn1];
 
            next1.addActionListener(new ActionListener() {
                public void actionPerformed(ActionEvent d) {
                    current.setIcon(null);
                     caballo(nextRow, nextColumn1);
                    ((AbstractButton) d.getSource()).setEnabled(false);
 
                }
            });
        }
        final int nextRow1 = row - 2;
        if (tienebotton(nextRow1, nextColumn)) {
            JButton next2 = mesa[nextRow1][nextColumn];
 
            next2.addActionListener(new ActionListener() {
                public void actionPerformed(ActionEvent c) {
                    current.setIcon(null);
                    caballo(nextRow1, nextColumn);
                    ((AbstractButton)c.getSource()).setEnabled(false);
 
 
                }
            });
        }
 
    }
private boolean tienebotton(int row, int column) {
        return (row >= 0 && row < HEIGHT && column >= 0 && column < WIDTH);
 
    }

any help will be much appreciated. Im really new to java and I cant figure it out :/. Sorry for the wall of text
