Anybody have a suggestion for a site similar to this (engine analysis and all) but also with human commentary to explain things to those of us whose chess skill earlier stage?

Svidler and Grischuk at chess24.com are fantastic, but they're both world class players and beginners will find their commentary and analysis difficult to follow. I'd recommend chess.com - Danny Rensch and Robert Hess are a bit more accessible.

The curious thing is that Carlsen’s ELO didnt’t get nibbled even after all theese consequent draws. They’re too close.

That's because ELO only gets updated at the end of a tournament, not every game.

At https://2700chess.com/ you can see the live rating with the effect of each game since the last periodic FIDE update. Expanding either Carlsen's or Caruana's rows will show you a list of the seven games since the last update, with a change of 0.0 next to each.

That's interesting. Do you have a source for that?

I always believed it is because either FIDE ratings are only updated once a month (see 7.1[1]) or because their ELO is too close, therefore the prob. of winning is 0.5 for both anyways.

Considering AlphaZero was orders of magnitude stronger than stock fish, it would be interesting to see AlphaZero's analysis if it was available. Edit: Alphazero's record against Stock Fish is 28 wins, 72 ties and 0 losses. In a 100 game matchup, AlphaZero had 28 wins 72 draws and 0 losses. I'd classify that as orders of magnitude better. https://www.chess.com/news/view/google-s-alphazero-destroys-...

AlphaZero was playing Stockfish 8. This is done using Stockfish dev which is more than 110 ELO higher than Stockfish 8 (see https://github.com/glinscott/fishtest/wiki/Regression-Tests ) and higher than what was reported for AlphaZero. Check out the Leela project, which is trying to reproduce and improve the AlphaZero project to also beat Stockfish dev: http://lczero.org/ (at this point they are about equal with Stock…

A 100 ELO difference is about a player twice as stronger. With a 100 ELO difference, Stockfish would have won some games.

28Win 72Draw and O Loss in my opinion reflects at least 300 ELO (8 times stronger).

Watching the game live with this open in another tab is cool. On Friday, it showed that Caruana had a winning position with a mate in around 30 moves. It was so non-intuitive that no chess player would have ever found it. But it is cool to see that the game "could have been" won.

True – yet extremely hard to find especially in a fortress situation end game when you can’t afford to wait cognitive brain to calculate new variations after each single move.

And also, Caruana would have had to trap his knight in a corner to get the win. To quote Kasparov:

The computer shows Black wins with 68..Bh4 here. But had Caruana played the incredible 69.Bd5 Ne2 70.Bf3 Ng1!! they would request metal detectors immediately! No human can willingly trap his own knight like that.

Chess24 has real-time human commentary as well as shorter post-game summary.

It is very fun but I think that to fully follow Chess24 commentary real-time you need to be FIDE 1900+

I don't have 1900+ rating and can follow most of it, although occasionally I need to pause the video to understand why some "obvious" things are indeed obvious.

It's true that without some basic knowledge of chess it would be hard to follow, but that can be said about many sports.

I like https://www.youtube.com/user/AGADMATOR. He goes over many interesting variations with clear explanations.

Am I understanding correctly that the score of 0 at the top means that the chess engine thinks their positions are exactly equally good?

When it's close to 0, it means the engine thinks the position is equal. But usually when it's exactly 0, the machine thinks the best move to play next must lead to a draw. As, in the next best move will lead to a worse position for the player making the move.

Exactly 0.00 can also mean that the engine has no idea what's going on.

Dumb chess question from a person that's never competed, why are international chess rankings divided by Male or Female? There are even olympic sports now that are mixed-gender such as Curling.

Chess is mixed sex. I'm guessing you're looking at the FIDE URLs like https://ratings.fide.com/top.phtml?list=men as provided on the FIDE (international governing body for chess) page here [1]. That URL seems to clearly specify men in spite of being linked to as "Top 100 Players", but the list includes both sexes. You'll find Hou Yifan on that list in place 91. The next highest rated female is Ju Wenjun who is 350th.

The reason for being able to see lists by the other classifications is because it's the same way that tournaments are frequently divided. Beyond having rating sections in tournaments there are generally also events that are only open to people below a certain age (or seniors events for players above a minimum age), or only to females. Females are also granted certain female only titles. For instance Hou Yifan holds the title of Grandmaster as well as the title of Female Grandmaster. The latter having substantially easier requirements.

To be clear, these divisions are all completely undirectional. Females, young, and old players can compete in any event and be rated against any player. Hou Yifan is regularly invited to top level events. For instance this year she was invited and competed in both Tata Steel and the Granke Classic closed events, competing against players including Magnus Carlsen and Fabiano Caruana. She scored a total of 0 wins, 10 losses, and 12 draws.
