Immediately someone answered: "Everyone who is strong likes to play up, and play with those who are hundreds of points higher than him. This is a student tournament, and the children who are good are all near the highest scores in their grades. He can't meet people who are higher than him for few hundred points, but it is easy to meet someone a few hundred points lower than himself, so he doesn’t want to go.”
So it's not that the tournament is strong, but that the tournament is not strong enough.
For high-rated players, it is really difficult to go to the national tournament to gain rating points. At least four of the 7 rounds are against low-rated players. If there is a mistake in the other three rounds, the rating will drop. No one is completely sure that they will be able to win the championship. If he is so sure, then the gap between him and other players will be several hundred points. In this case, even if he wins, he will only gain a few points.
If you can't gain points, why go? There are still a few strong players going there every year. We'll talk about it tomorrow.
