      $IS = "<img src=blank1.gif>"; //illegal square image

      $cBoard = array(
            array($IS, $R, $IS, $R, $IS, $R, $IS, $R),
            array($R, $IS, $R, $IS, $R, $IS, $R, $IS),
            array($IS, $R, $IS, $R, $IS, $R, $IS, $R),
            array($ES, $IS, $ES, $IS, $ES, $IS, $ES, $IS),
            array($IS, $ES, $IS, $ES, $IS, $ES, $IS, $ES),
            array($B, $IS, $B, $IS, $B, $IS, $B, $IS),
            array($IS, $B, $IS, $B, $IS, $B, $IS, $B),
            array($B, $IS, $B, $IS, $B, $IS, $B, $IS)
      );

      echo "<table border='3' width='200'>n";

      foreach ($cBoard as $row){
          switch($row){
