Petr and Karel played a series of chess games. They agreed that a player would add 3 points for a win, subtract 2 points for a loss, and no points would be awarded for a draw. Their friends wanted to know how many games Petr and Karel had played and who was currently leading, but they only found out that Petr won six times, drew twice, lost several times, and that Karel has exactly 9 points. How many games have the boys played, and who is currently leading?
