This issue has been beaten to death. One side is frustrated because they want fair competition and the other likes telling them that it’s going to make their kids better. The truth is playing older kids in a tournament is not making them better it’s making the parents of the older kids feel better. If you truly believe that, then you must have a 2030 or 2031 playing up with the 2029’s which is why you’re on this thread. Doubt it. Practicing all year with older kids would likely make a better player but a game at a tournament just discourages kids. It’s cheating and everyone knows it no matter how you justify it.
