Is that a real question? Because if it is, you are giving an opinion on TCEC without knowing how it is organized.When are the games played?The only (or one of the few) programmers I did not see in the TCEC chat room is you, and that explains why you think nobody gathers.
As far as prestige goes, TCEC is not a tournament in the strictest sense of the word. No one "gathers".
Actually, it is very convenient and one of the secrets for its success! you can watch and chat with other spectators, programmers, and organizers the whole weekend if you want.
I am in my office 8-5pm (or later with 6-7-8pm classes on occasion). Weekends are my only chance for the most part. An event that spans weeks is not exactly convenient.
Many do watch it.
The CCT events are done over two days, and don't take all of both days.
I'm not looking for a new career watching a long-running chess tournament.
Response to what? The prestige cannot be debated. Prestige is given by spectators interest, coverage, impact outside the field, and peers respect, which drives motivation to prepare and win it. Just looking at how much talk and preparation for TCEC both SF and Komodo team had, it is great hint about how they respected the tournament. Not to mention that many other authors provided last minute development versions. Even between stages! I have not seen (non-author) FIDE titled players very interested in any other tournament outside TCEC. I saw some in TCEC chat rooms.
The ICGA events started off as 4 day events, once a year. Doable.
So no response? Is longer better? CCRL is longer. Is shorter better? WCCC is shorter. So what makes something "in the middle" the most prestigious? Just a casual vote?The prestige of TCEC is not under debate.
The time period is impossibly long to get a group together. So for max prestige, why is not topping CCRL the "cat's meow"?
