What do white and black have to do with it? It's clear that there are strong players, weak players, and average players. The criteria are: results in team competitions, results in Masters tournaments, and the subjective opinion of the judges about the strength of a player based on their experience in personal games.
Here's how I envision it: four groups are created, two for beginners, and two for strong/average players, with 6 people in each. From the groups with experienced players, 5 people advance, and from the inexperienced groups, 3 of the weaker players advance, totaling 16 people. Then, a playoff is held (if anyone thinks this is unfair, I disagree, because when forming the general groups, the number of weaker players who make it to the playoffs would be even smaller). Then, the playoffs proceed based on the final results: the players who took first place in the experienced group play against the players who took third place in the beginner group, and so on. This way, the weaker players can play normally among themselves, gain experience, and, accordingly, compete in the playoffs with stronger players.
We can either have a playoff or use a double-elimination bracket if we want the tournament to last longer, or a single-elimination bracket if we want it to be shorter.
That's how I see it.
P.S. Regarding white and black, it was an allegory inspired by the inflexible regulations of the TE Masters
