What does "first decisive game in the classical rounds of a world championship in over five years" mean?

lots of games at this level result in draws, this was a win.

I wonder if this is a limitation on how humans conceptualize Chess. Do games played with computers either vs human or another computer frequently end in draws?

If not, maybe there is some insight to be gained to raise high level play even more.

When Carlsen previously defended his title agains Fabiano Caruana, all the classical (slow) games were draws. The championship was decided by rapid games, where Carlsen demolished Caruana.

I love both playing and watching rapid chess, but I think it's better for the world championship to be decided using classical time limits. That way, we get more interesting games, rather than the indignity of top players blundering while under time pressure.

High level computers draw each other almost 100% of the time and beat humans 100% of the time.

Vishy Sir during the end game commentary said that the engines say it’ll be a draw. Where/which move did Ian make the mistake? Anyways, hats off to everyone involved. Magnus, Ian, commenters, and the chess twitterati. What a game! ~8hrs!!!

From the post game interview

Q. What was the decisive moment?

“I don’t know,” he [Carlsen] says. “But it felt like at the end when I got [133. e6] and maybe there was still some miracle defense there, but it didn’t really feel that way. At that point I felt very, very good about my chances.”'

Well done to Magnus. To Ian. To the commentators. This was an unbelievable 'play' in three acts. A game for the chess books. Great quality match so far and I hope Ian comes back from this blow and makes a fight of it. I believe he will.

It was an absolutely incredible match to watch live. Historical.

My jaw dropped when Magnus ignored his rook being attacked at the end in favor of the potential fork with his knight. It is ultimately what led to the sure win.

Bit of a spoiler :( I prefer to watch analysis of games from YouTubers like Agadmator or Jerry from Chessnetwork and discover who the winner was by watching the game. I wonder if these long games are not particularly helpful. Most chess final games end in draws as players are reluctant to create an imbalance and instead play it safe. There tends to be more exciting games played in games with a shorter time limit. I'm…

> Bit of a spoiler :(

I get your sentiment but this is really exciting news in the chess community. A win after so many years!!

In the game theoretic sense, it was move 130... Qe6 which moved the endgame from drawing to losing. We knew that under perfect play the game had been drawn since 115... Qxh4, since that's the point at which the pre computed table of endgames has the position (which is also why we know the exact move where the game from drawing to winning under perfect play).
