On a side note: I think Pentagram did an amazing job with the WCC branding [1] in 2014. It's ridiculously non-conventional for a serious organization such as FIDE to adopt it. They did reject the proposal for Shuka Design for the new "pawnographic" (as it was hastagged on twitter) logo [2] for the 2018 championship and only kept the arms tangled up around a chess board. Still, its extraordinary and personally I love…

Thank you for sharing this. I love the logo, but IMHO the overall look of the 2014 design (type, grid, illustrations) is a little too similar to theguardian.com aesthetic.

Edit: I was commenting on the 2014 design.

Another nail-biting draw!

It's hard to change a game that's so old, but draws shouldn't be allowed, only stalemates. Imagine if the Lakers played the Warriors, and late in the 4th quarter, the game is tied, and LeBron and Curry decide they are tired, declare a draw and go to their locker rooms. Not particularly satisfying.

Your analogy doesn't make sense. In basketball, if your opponent gets tired, that gives you a better opportunity to win. In chess, if the game nears the end and neither of you can see a way to win, then there's no good opportunity. Your analogy would make more sense to say the basketball game was tied and there are three seconds left on the clock and both players have broken wrists. Playing three seconds of game to risk injury is not worth it for either player.

It also doesn't mean the game was unexciting.

Women aren't naturally less interested in or good at chess. There must be some other explanation for the top 90 chess players all being male.

What evidence is there that this is true?

There exist women who are good at and interested in chess.

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.

Err...sorry no. At least not for Stockfish (maybe for AlphaZero or LeelaZero).

0 means that the position is exactly equal (material + positional)

The engine always has an idea of what's going on through simple material calculation + positional heuristics (although it maybe be flawed)

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.

Almost all tournaments are mixed. I have never played a men's only tournament in my life and I have played fair bit of them in my chess career life.

So, 70 million nps or about ~3x 2950x threadrippers [2] is relatively weak cpu compared to 80 thousand nps or approximately 2x 2080tis [3] for Alphazero? > AlphaZero compensates for the lower number of evaluations by using its deep neural network to focus much more selectively on the most promising variation [1] Even if you compare CPU to GPU by price, and not speed, it seems pretty even. It clearly has to sacrifice…

AlphaGo engineers didn't really know how to configure Stockfish correctly. The computer itself was strong. But the weird timing setup, the disabled databases (ie: both opening book AND endgame book was disabled. Stockfish normally plays PERFECTLY when the board is reduced to 6 pieces or less, as well as perfectly knows the winner / loser in every 6-piece setup. But that was disabled for the AlphaGo games) Without the…

It's not that they didn't know how to configure it correctly; some of it was purposefully (and rightfully) disabled to see real difference between stockfish and AZ.

Remember that if stockfish uses tablebases and opening books it's really "cheating" by using human knowledge.

Although I am surprised that they reduced the hashtable so much and also used stockfish 8 when stockfish 9 was available. It was not RAM but just the hashtable size also their "test" has been replicated by plenty of people.

We have our own "replica" of the NN playing chess in lichess.

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?

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

Second agadmator, lots of personality and humor along with the detailed analysis.

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.

Opening book I agree, but tablebases are definitely not human knowledge. They are a bruteforced database of every possible position, or in essence a precomputed position. Put simply, giving a massive time advantage to the user during the late middle and endgame.

So if A0 wasn't built to access them, but stockfish did in the match, then that would be an unfair advantage.
