I think it's pretty self-evident that chess as a game and sport is not in the same era that is being described in the "1945─present" subsection of the "history" section. The hallmarks of the era that are specified are, exhaustively, the following: 1) FIDE introducing a bunch of things, such as titles, changes to tournament structure, etc 2) Soviet/Russian dominance at the highest levels 3) chess theory being revolutionised by Botvinnik. The current era of chess shares none of these hallmarks: 1) the last major introduction by FIDE was the title of Candidate Master in 2002, but that is barely something worth even mentioning in a section that's supposed to summarise all of chess history 2) the last Soviet/Russian world champion was Kramnik,who lost his title almost 15 years ago 3) modern chess theory has been formulated almost entirely through the means of chess engines and game databases such as those provided by Chessbase ─ both features that did not exist 15 years ago. Additionally, chess as a game is completely different to what it was let alone 15 years ago, but even a couple of years ago: the vast majority of chess games is played online (a trend which is likely to continue even when the pandemic is over); in-depth analysis with superhuman engines like Stockfish is now accessible for free to everyone on websites like chess.com and Lichess ─ in combination with other factors like the existence of online tactics trainers and courses,this has made studying chess far easier and more efficient than previously and resulted in the average level of play continuously rising in the past couple of decades; top players engage with the chess community far more closely than they ever have done by streaming on Twitch, releasing videos on YouTube, and producing online courses; more generally, over the pandemic, online chess has grown into an e-sport, with e-sport teams now routinely signing chess players and with "chess" being one of the most-watched categories on Twitch; and, of course, it's hard not to mention (as far as I'm aware) the biggest surge in popularity in history spurred by a combination of the show the Queen's Gambit, online chess growing in popularity due to COVID-19, and online tournaments such as Magnus Invitational and even PogChamps.The past 15 years have probably seen more change in chess than all of the centuries that came before them, yet none of that is even mentioned in the "history" section. Does anybody mind writing up a subsection called something like "2000─present: online chess and computer domination" detailing everything that I described in this post?Maxipups Mamsipupsovich (talk) 22:32, 15 April 2021 (UTC)
@Bruce leverett: @MaxBrowne2: Just informing you that I've finished writing up the new section that I had initially proposed. Maxipups Mamsipupsovich (talk) 13:35, 20 April 2021 (UTC)
I haven't seen any reliable sources that refer to "The Boom" with a capital B. I am still not convinced that a TV series based on a novel is a uniquely significant event in the history of the game, or that the recent surge in online games is anything more than a blip caused by the pandemic. There is a clear WP:RECENTISM bias here. MaxBrowne2 (talk) 08:04, 21 April 2021 (UTC)
Hopefully most of them are improvements. I'll wait for the dust to settle. MaxBrowne2 (talk) 00:45, 23 April 2021 (UTC)
"In fact, the most important openings have now been analysed over 20 moves deep,[98] sometimes well into the endgame,[99][100] and it is not unusual for leading players to introduce theoretical novelties on move 25 or even later.[101][102][103]"
I am inclined to remove this, but because it looks non-trivial, I'll wait a little while for other suggestions. Bruce leverett (talk) 03:59, 23 April 2021 (UTC)
