Selection for FB-3.

In my opinion, it's a bit inconvenient, but the ranking by strength is better. You can actually see who's good. With groups, you might get lucky, or you might not in the playoffs. Of course, the same applies here, and maybe even to a greater extent, you can get lucky once or twice. But the winners will be determined fairly. There won't be problems like with a bracket of 20+ pages, and we'll be able to eliminate inactive players almost immediately. In terms of convenience, groups are more convenient. We'll keep this in mind for the future.
