Class: visualboard

Parameters:

If castling rights have been taken away by a king or rook move, the button is not displayed. This function uses Games_Chess::canCastleKingside(), Games_Chess::canCastleQueenside() to find out.

If $_GET['start'] is not used, it checks for $_GET['kingcastle'] and tries to castle kingside if found. Otherwise, it looks for $_GET['queencastle'] and tries to castle queenside

Using the alert() function, this method asks the user if they want a queen. If they click Cancel, it asks if they want a rook, then knight, then bishop. If they cancel on bishop, it promotes to queen to avoid any illogical possibilities

first, it checks for a pawn promotion and adds the promote move to $moves using game::addpromote(). Then it moves the next piece by calling domove(). Then it checks for stalemate and checkmate, and stops the gameplay if either condition is met. It creates a visual representation of the board using abstractboard::createrows(), and displays the chessboard by linking together the display of each row on the chessboard using row::draw(), and finally the movelist using game::draw()
