Anyone know if Naroditsky is working for Chess.com or anyone else for the World Champs? I find him and Svidler are the best at explaining super GM level play to intermediate players like me.

Interesting first game, I wonder if Nepo is going to be put off playing e4 in his white games? He wasn't exactly up against a wall, but he had to be extremely precise to hold off Magnus' pressure and never really looked like he was playing for a win at any point.

No doubt the Russian super computer has been fired up to analyse the poo poo out of this Na5 line overnight.

What analysis engine does Chess.com use? Obviously Lichess uses Stockfish but I about poo poo myself earlier when I was fiddling with openings on Chess.com and did a Ruy Lopez, Morphy Defense. Typically after 4. Ba4 Nf6 I would castle kingside as white, and here's why I have my question. Chess.com gave 5. O-O as a 100% black victory, while Stockfish on Lichess is giving it 30% / 52% / 18%.

As an aside, I really like how Lichess explains the tactics. Going a little further took me into a closed Ruy Lopez and then I scrolled down and saw this whole thing explaining 4 or 5 different next moves for white and the implications of each. This is kind of the stuff I need, and how Chess for Dummies resonated for me 15 years ago. That book is how I learned enough to understand open files, back rank mates, etc.

What you're looking at there is opening explorer, not their analysis engine. I'd guess that the results you saw are based on games that you've played at each website - the master level games database (that chess.com and lichess share) would be something like 40/30/30 for a Ruy Lopez.

Analysis will give you a centipawn evaluation for a position (e.g. +0.7 or -2.4) rather than a record of previous games.

Both sites use Stockfish. If you left them both to run a position for an hour you'd get the same evaluation, but on default settings it's only running for 30 seconds or what have you so there will be very minor discrepancies. You can see this by even putting the same position into Lichess at different times, the evaluation won't always be exactly the same at a low depth just based on which lines Stockfish happens to run down. Not that the difference between +0.5 and +0.7 is at all meaningful to a human anyway.

3.e4 in response to black accepting the Queen's Gambit is a perfectly respectable line and it's what I play.

The Ruy Lopez is super popular at all levels, but it is a crazy theoretical opening that has been studied to death and has a ton of traps as far as 15 or 20 moves down certain lines that are not intuitive to avoid if you don't have deep knowledge. I steer clear of it because even at like 1400 you never know if you're playing someone who may be a poor strategic player but they've read a book on the Ruy Lopez and will just out prep you in the opening.

The only one on the front foot was Karjakan went up a game didn't he? But that was after Carlsen missed winning chances in one of the others if I recall.

From memory, Carlsen was really off form against Karjakin in 2016. Had very strong near-winning positions in three games where he uncharacteristically failed to convert his advantage in the endgame before Karjakin won a game as black where Carlsen played recklessly pushing for a win in an equal position. Carlsen did play exceptionally well to level the match with his win in game 10 (I think?) and then obviously dominated the tiebreaks, but really he should've won the match at least 2-0 in the classical portion, if not by more.

Played an over the board 7 round Swiss with 13+2 time control yesterday, first tournament in person ever for me. Finished 2 wins and 5 losses. All the games were close and competitive other than one where I foolishly went into the Italian as black depsite not knowing the theory and got blown off the board in about 25 moves, and another where I was holding my own in a tense position against a stronger player until I blundered a full rook in such a comedic fashion my opponent spent two minutes thinking before capturing assuming it was a tactic. I found it much harder staying aware of those dastardly long diagonals in person as I'm so used to the flat 2d online board.

Overall though was a great experience and looking forward to doing again in the new year.

If you look at the stats, that second puzzle has had only about 1300 attempts, so is fairly new. The ratings take a while to normalise (they are dynamic based in the pass/fail rates of players at different elo, not set in stone by the creator) so for recently added puzzles the rating can be higher or lower than it probably should be.

A good rule of thumb is two more attacking pieces than defending pieces. Here black has a Queen, Rook and Bishop versus just a white Bishop defending the King. That means there is very likely a forced mate somewhere.

Finegold and Naioditsky are the best teachers on YouTube imho because they combine high level chess ability (both strong GMs, especially so in Nairoditsky's case) with a lot of experience teaching kids. It really shows in how they explain concepts that they have done a lot of teaching and know what works.

Someone like Hikaru is of course an insane player, but he can struggle to explain precisely his thought process in a way a sub-2000 player can understand clearly.

I guess never say never, but this cycle is Hikaru's last realistic shot to play in the World Championship and even then he's probably no better than fourth favourite if he qualifies for the candidates in the Grand Prix (which is far from guaranteed). If he passes that chance up then he may as well have actually retired.

At the very least he could do great numbers on twitch and youtube doing recaps of his games in the candidates.

Nepo fought well and had Carlsen on the ropes once or twice, it was exciting. Then he lost a game and disintegrated which was again interesting, just in a different way. I believe he'd be psychologically stabler in a rematch, and with Carlsen possibly less motivated, it could be a close call.

Fabi drew all the regular games and I don't remember him really threatening, or anything else interesting from that match. And he doesn't look any stronger now than he was then. I can't imagine why you'd want a repeat of that match, unless you're just rooting for an American player. Personally I'd even watch Karjakin rather than Fabi, politics aside.

From what I remember of the Carlsen-Caruana match, Fabi never seriously threatened to win a game while Magnus had two or three big chances but failed to convert any of them. Magnus was pretty scathing of his own performance afterward, said it was the worst he'd played in any match ever.

I was literally about to make this post. They have two world championships in short formats every year.

People were already complaining Nepo lost games in the WCC because he made dumb blunders. How exactly will shortening the time control and therefore reducing the quality alleviate that complaint?

As for 14 games being a long time, if anything I disagree. A longer match would encourage enterprising chess. As it is in a 14 game series just one defeat is so significant, and going two losses down virtually ends the contest, that it leads to more conservative play. They should change the format to a first to X wins, like Fischer wanted. Maybe first to four wins.

Are the top engines dominant against super GMs in the rapid/blitz time controls?

Yes, it's not even close under any time controls. Stockfish and AlphaGo etc. are like 3500 Elo. Them playing Carlsen is like Carlsen playing a strong but untitled club player.

1. b5 axb 2.axb and I'm pretty sure the bishop has to sacrifice in order to stop the promotion. Then up a knight for the pawn you should convert the endgame.

Edit: actually maybe not that endgame looks a bit tricky

Or Fischer accusing (probably correctly) the Soviet players colluding to shut him out of winning the candidates.

Or the 1978 world championship between Karpov and Korchnoi.

quote:

Karpov's team included Dr. Zukhar (a well known hypnotist), while Korchnoi enlisted the help of two American Ananda Marga yoga specialists who had recently been convicted of attempted murder and released on bail. There was more controversy off the board, with histrionics ranging from X-raying of chairs, protests about the flags used on the board, the inevitable hypnotism complaints and the mirror glasses used by Korchnoi. When Karpov's team sent him a blueberry yogurt during a game without any request for one by Karpov, the Korchnoi team protested, claiming it could be some kind of code.

Also I'm pretty sure there was a candidates in the cold war era where the Soviet government basically ordered a player to lose by threatening his family. Can't remember which one specifically.

The podcast he did with Magnus in August (so pre all the cheatgate stuff) is more interesting imo.

Magnus is the best chess player who's ever lived and he doesn't even, in a traditional sense, study chess. He doesn't solve studies or do tactics training or analyse his past games.

Reading between the lines it seems to me the big reason he doesn't want to play the World Championship (at least in its current format) is that is necessitates crazy deep preparation focused on just one opponent and Magnus hates doing that. He literally turned down working with Kasparov when he was younger because the first thing Garry did was ask him to analyse games he lost.

It's kinda crazy that every single piece of advice anyone will give you to improve your chess - tactical exercises, opening prep, endgame practice, puzzles etc - the best chess player ever is like "nah, I'm good I'll just think about chess subconsciously whilst I play tennis with my buddy all afternoon".

Yeah I agree that it being decided by tiebreaks is unsatisfying, regardless of the incredible drama it created at the end.

First to X wins is the best format I think. Encourages attacking play as you can't sit on a lead and means if you're behind you're theoretically never out of it. The farce of the 1984 championship has killed that forever though.

The c2 pawn in this situation is what I've heard called an 'overworked' piece. There's a saying that if one piece is defending two things at once it isn't really defending anything. Whenever you have two pieces defended by the same piece and nothing else there is very often tactics afoot, it's a good thing to be looking for all the time in any position.

My first thought is the white queen is the one getting in the way of attacking the king, so g6 is fairly obvious here to me. The queen doesn't have many good squares to go with the rooks being so dominant either, so g6 punts it far away from the defence. Then you play Re4+.

Redmark posted:

It seems like this would go like Qb5 Re4+, Kd2 Qxf2+, Re2 and I don't see the mating net, though Black can still trade down into a winning endgame.

In your position after Qxf2+, Re2 just walks into Qxe2+ as the rook is double attacked. The king needs to retreat to the back rank rather than blocking with the rook.

I think the white Queen needs to go to c5 to keep an eye on f2 otherwise white is in deep doodoo. c5 is still pretty passive though and Black should win very comfortably as long as you stay patient and don't trade rooks (which would dilute your immediate attack).

Looking at it again, I think g6 2. Qc5 Qe4+ is the correct continuation for black as it enables you to play Rd3+ or Qd3+ depending on which way the white king runs.

Started playing blitz chess online after a long break, only really played 15 minute rapid online or casual no clock games for the last year plus.

And just now got my first ever smothered mate in a game. :unsmith: Sporting of my opponent to play on and see it on the board.

https://lichess.org/BmwcKwKV/black

Please ignore the obvious missed Qxe3+ which is crushing earlier in the game, I am still so much worse at 5 min than 15 min. I feel like I play faster without properly processing the position even when I don't have too at the blitz time controls because I feel like I have less time than I do.

Daniel Naroditsky talks constantly in his videos about "Type-1" undefended pieces e.g. literally undefended and "Type-2" which are pieces only defended by one other piece (not a pawn). Looking at your opponents set up and seeing where the type one and type two pieces are is a good way to formulate an attacking plan.

First, look at all checks and captures (of course you should do this before every move). The knight trade is the most obvious move to analyse. When I quickly saw the knight is only defended by the queen, it was pretty simple to figure out the tactic. But you have to train yourself to look for things like that.

If you are at the level where it is worth studying opening theory then you will gain more by looking at a different opening than the London System. The whole point of the London is that you don't need theory and you can low effort yourself into fairly dull, equalish middlegames and wait for your opponent to make a mistake. If you want to study lines and start playing for an edge in the middlegame, but are new to opening theory and don't want to fall into the abyss that is Ruy Lopez/Sicillian theory, then I would suggest looking at the Scotch if you like open and attacking games.
