Thoughts on Getting Better at Chess
Players need to work on tactical pattern recognition and calculation. These are two sides of the same coin. We can't calculate very well unless we can also recognize the patterns on the chessboard.
My personal goal is to be able to either recognize or calculate 3 move tactics while playing speed chess. I think that there is a difference from 1500 to 2000 where the players go from calculating tactics to recognizing more of them instantly. Starting in the mid-1990s, I spent a great deal of time studying tactics and this took me from 1800 to 2000.
Many people claim that speed chess is bad, but I don't agree. It builds pattern recognition and teaches quick calculation, although it depends upon the person. Speed chess can create bad habits and some people just need more time to calculate.
There is this idea called "The Woodpecker Method" and a book by the same name. The method is to study the same set of a thousand tactical problems repeatedly. Each time you do them you will get faster at doing the entire set. Another author, Michael de La Maza, had the same idea in a book called "Rapid Chess Improvement". Before he wrote his book, he first published it as an article, but first, he sent the article to me to ask what I thought of it because I had already created a website advocating a similar idea.
I inadvertently discovered this method when I created my chess lesson website around 1996. The Internet was still very young and there wasn't much chess content so Chess Life magazine gave me an "award" for my site. After I spent months creating the 1, 2, and 3 move problems on my site, I challenged myself to see how long it would take me to go through each set of the white-to-move and black-to-move problems. It took a long time. However, the second and every subsequent pass was faster. I think that a 2000-level player should be able to get through each set of 1, 2, and 3 move problems in 30 minutes, but only after much practice. I have achieved this many times, but now I fall short so I intend to study the problems more.
I've been accused of just memorizing the answers to all my problems and not doing any actual tactical calculation. This is half right. For some problems, I remember the answers, but for others, I just remember the pattern involved and a few I don't remember at all. Even if the accusation were 100% correct, this would not be a bad thing. Chess skill relies on remembering what we have seen before and recognizing those patterns over the board.
Some people improve just by playing a ton of games, and this can work, but I think that it is less effective than studying tactics. Although most people play a great deal, I don't play many games and prefer to spend my time studying chess.
I also have thoughts on what it takes to become a chess master...
In the late 1970s, I studied basic King and Pawn endgames and became proficient at them. In the mid-1990s I studied more complex king and pawn endgames, all of which were from my games, and became skilled at those. I didn't have to memorize these endgames because I understood why the moves were correct. It is easier to retain information if you understand it, but this is harder to apply to other areas of the game like openings. I think that endgames are easy to learn, except the more difficult ones like the bishop and knight mate or the queen versus rook ending.
I have a full course covering King and Pawn Endings on my website.
My point is that I think that it is possible to take one small area of the game and master it. I have done this with King and Pawn Endgames. Chess is not just one skill, but many, so I think that a person could master chess by just focusing on one aspect of the game until they master it, and then move on to studying a different aspect of the game. For example, I think that it is possible to learn a particular opening as well as a master, although this would require much effort.
Online ratings mean very little to me. I can't control how well the anonymous person on the Internet plays or if they are cheating, which many of them do. What matters to me is how well I play. Likewise, losing games at the chess club doesn't phase me. I see losses as an opportunity to learn something. My goal is to always keep learning. Losing a game doesn't mean that I am a bad player, and I have confidence in my chess skill. I have no problem playing and losing to stronger players because my goal is to play the best that I am able regardless of the result.

Magnus explained why Chess is popular
https://www.youtube.com/shorts/aGc5lYv3cvI
Chess is too complicated for humans to completely master, but Magnus Carlsen has come closer than anyone.
KQ vs. KR Endgame
Recently, I have put much effort into learning the endgame KQ vs. KR. This is probably the most difficult chess endgame to study. Many moves are counterintuitive compared to other endgames where you crowd the enemy king until you get forced checkmate.
It tempting in many positions to check horizontally or vertically. This is often wrong, and the correct procedure is to check once or twice along a diagonal before checking horizontally or vertically. In some positions, the best move is to not check but attack the squares around the opponent's king. To win, you have to be able to calculate well.
Against a good defense, there is a desired position that you must reach to separate the King and Rook. I note this position on the web page below.
This is also the kind of ending that you might only see twice in a lifetime. Because of the difficulty, studying it might not be time well spent. You cannot learn it overnight or just through general principles.
However, I want to be prepared for it.
I have created 33 study positions on the webpage below. These start with the easiest and progress gradually to the more difficult. Most problems build upon the ones that came before them.
If you are interested, scroll down until you see "KQ vs. KR" on the right side.
This is not yet complete. I plan to add more positions regarding the "3rd rank defense" and how to push the enemy king to the corner.

As far as I know, ICC was the first place on the Internet to play chess.
I joined ICC back around 1995. I didn't even have the World Wide Web at that point. I had used a text-only version of the Internet called "Usenet" for about five years. Within a few months, I downloaded Netscape and accessed the World Wide Web for the first time. It was slow and I had no idea what to do with it. There was hardly any content.
So back then to play chess on ICC you had to download a program that would act as a graphical user interface. It communicated with the server using text but displayed the board on the screen. The most popular program was called "Ziics", but it would be later replaced by a program called Blitzn which was the standard until recently.
BTW, back in the mid-90s, I was having an online chat with the owner of ICC, who told me that he was inventing a new time control, which was less than 3 minutes for the whole game. He wanted to know if I had any ideas for a name for the new time control. I tried to come up with something, but he suddenly had an inspiration and called it "bullet". I told him that this was a terrible name because what do guns have to do with chess? However, he stuck to his guns, sort of speak.

Hitler vs Lenin | Chess Game in 1909
https://youtu.be/GYUQYsLWlMI?si=uvwAv7afS2WIOh6E
There is an old story about Hitler and Lenin playing a chess game and there is even a drawing depicting this, but many historians think that it is a myth.
Many famous people played chess. Albert Einstein played Robert Oppenheimer. Mike Tyson played Muhammad Ali. Humphrey Bogart and John Lennon were both officially Experts. Many movie stars would play chess on movie sets while waiting for their scenes, such as John Wayne, Lauren Bacall, and Tony Randall.
Benjamin Franklin was an avid player and met the French master Philidor.

Magnus on Generational Shifts
This is interesting. Magnus Carlsen relies a great deal on intuition. In an interview from about a dozen years ago, he said that he usually sees the best move right away, but still has to calculate to ensure that intuition is correct. His pattern recognition is the best in the world. He seems to know more about chess than anyone else.
Kasparov and Fischer were better at chess calculation than anyone in their generation. As a result, they tended to play aggressively. Karpov had a completely different style, where he was a strategic player who relied on being able to outmaneuver his opponents. Magnus Carlsen can do both, making him a nearly perfect chess player.
However, in recent years, we have seen the rise of many young players, especially from India and Asia, who could someday become World Champion.

Push to 3000 on chess.com puzzle rating
The puzzle ratings on chess.com don't correspond in any way to USCF ratings. I complained about this to chess.com, but they responded that their puzzle ratings are where they want to them to be. (BTW, the upper limit on puzzle ratings is ridiculously high at around 32768. Some people have actually reached this limit. For computer nerds like me, this matches the upper limit on a 16-bit signed number. This tells me that they are using 16 bits to store ratings in their database.)
I wanted to see if I could push my Chess.com puzzle rating up to 3000. I've been there before, but it is a hard rating to maintain.
My puzzle rating averaged around 2935. At this level, I am almost as likely to fail to solve a puzzle as I am to succeed.
I had a theory that if I did enough puzzles I could reach 3000 through a "random walk". The idea was that if I bounced up and down enough I would eventually hit 3000 through random variation. This wouldn't mean that I deserve to be at 3000, but got lucky.
It appears to me that chess.com will present puzzles with a sizeable range of difficulty. This is where luck plays a factor. However, every time my rating would creep up, I would face problems that seemed too difficult. This definitely took me out of my comfort zone.
It took me about 2.5 hours to reach 3000. However, to get there I had to analyze at a deeper level than I am used to. Whereas the simple chess problems on my website are designed to build pattern recognition, it seems to me that the puzzles on chess.com are more of a measure of how well a person can analyze. However, pattern recognition is still a factor.

NEW Hans Niemann Chess Cheating Accusations
https://www.youtube.com/watch?v=BJcYMCqCJ2A
Either Hans Nieman is cheating or he soon will become a world top 10 player.
Human beings can be sociopathic, and humans also have a great capacity for delusional thinking. I have met many narcissistic chess players, and these people can be extremely annoying. I am pretty sure that narcissism is more common among chess players because competition appeals to people's egos.
This describes Nieman whose egotistical statements have turned opinions against him. Someone like him might feel entitled to win regardless of ability. In this case, a person could justify cheating because they think they are not getting the recognition they deserve. He could be motivated by a desire for acclaim.
I hope Nieman is the next great chess talent, but I don't know if this is true.
If I have time, I will analyze his games from this tournament.

How to Stop Blundering and Start Improving Your Chess Game: Advice from a GM
https://www.youtube.com/watch?v=J4Gcl0YK034
Apparently, GM Ben Finegold believes the same things I do.
His comments at the end are funny.
2023-11-14
One of my best chess tactics
I consider this to be one of my better chess tactics. Of course, we have seen Grandmasters like Bobby Fischer make similar moves, so chess masters probably consider this to be pretty routine.
The Reason People Don't Get Better At Chess According to Ben Finegold
As a chess YouTuber, Ben Finegold is not my favorite. His presentation is just not as interesting. He seems rather casual, less informative, and cocky.
However, I like the point he makes here, which is that people suck at chess because they blunder and don't learn from their mistakes.
He is only partially correct. People try to learn from their mistakes, but they do so by just playing. It is repeated trial and error. People don't retain information this way, although if a person played a great deal then they would make progress up to a point, which I think would be around the 1700-1800 level. It is difficult to get better than this without some serious study.
So the way I learn from my mistakes is that I analyze as many of my games as I have time for, and I have a system for reviewing my past mistakes. This takes much time, and maybe some people would feel that the time would be better spent just playing.
I strongly believe that studying tactics is critical. There were specific tactics that I studied that took me from 1800 to 1900, and then a different group of tactics that took me from 1900 to 2000. I studied tactics 30 minutes a day almost without fail, which meant that I spent hundreds of hours studying tactics. However, this is something I haven't had time for lately, so my most recent goal is to study tactics for 20 minutes per day.

This is an opening trap that everyone should know, even if it wasn't part of our lessons.
In addition to this, in the Queen's gambit accepted, if Black tries to accept the gambit and hold onto the pawn, it is always bad:
This is a speed game I lost in Utah in the 1990s.

Bobby Fischer considered the knight to be worth 3 pawns and the bishop to be worth 3.25. I independently came to the same conclusion, after first valuing the bishop as 3.5. As evidence for this, a bishop and knight trade for a rook and a pawn is considered a bad deal. Likewise, in most endings, two bishops are technically winning against two knights, although there are exceptions where the reverse could be true. So the value of the pieces is very much position dependent.
My friend Al made a video about how valuable the knight can be in practical play between human players.

Chess Level 08: White to play
This is a simple attack and my opponent allowed a mate in 1. However, the computer line is complex and I think pretty interesting.

Carlsen: Haven’t Studied Chess Recently; It Showed.
Paul Morphy was considerably better than his contemporaries. So was Bobby Fischer. Neither benefited from computers, databases, or modern opening theory. For this reason, it is harder to compare the skill level of their play with the level of the top current players.
Gary Kasparov was only a bit better than his contemporaries but remained World Champion for 15 years.
Magnus Carlsen is the closest thing to a perfect human chess player. He knows more about chess than anyone ever. He definitely would lose to a computer, but that would be like a math contest against a scientific calculator, or a boxing match with a brick wall. Computers really are perfect, or at least close enough that we can't tell the difference, whereas all humans make mistakes, including Magnus.
As good as Magnus is, he is only a bit better than his contemporaries. There are a number of players who are not far behind.
Bobby Fischer reportedly had an IQ of 180. He was incredibly brilliant. I have heard that Magnus Carlsen has an IQ of 190. He is also incredibly brilliant. I don't know how one quantifies the difference between 180 and 190, especially half a century apart.
Magnus Carlsen once admitted that he had to drink less to play chess well. I have seen him play speed chess online while apparently drunk but he still won because he can play intuitively almost perfect chess. I've seen Russian Grandmasters also win while drunk. So, therefore, I've been wondering if Magnus Carsen is an alcoholic.
In this interview, he looks more disheveled than usual. It is also a bit odd that he decided not to participate in the World Chess Championship, giving up the World Chess Champion title that he has held for ten years.

Magnus Carlsen - Wikiquote
"I think in general the future of classical chess as it is now is a little bit dubious. I would love to see more Fischer [Random] Chess being played over-the-board in a classical format. That would be very interesting to me, because I feel that that particular format is pretty well suited to classical chess as basically you need a lot of time in order to be able to play the game even remotely decently. And you can see that in the way that Fischer [Random] Chess is being played now when it is played in a rapid format. The quality of the games isn't very high because we make such fundamental mistakes in the opening. We don't understand it nearly enough and I think that would increase a lot if we were given a classical time control there. So I would definitely hope for that." — November 2020 [1]
"I'm certainly somebody who hopes for more 960 in classical format because I feel like 960 is not that suited to rapid and blitz because you're just gonna play too poorly. You're just gonna have absolutely no clue, but if you actually have time to sit down and think for half an hour on your first five moves, then maybe you can get some more understanding of the game."— in a stream with Eric Hansen, April 2021 [2] 53:29 - 54:36 [3]

World Chess Championship cutting to the chase

"The match is best of 14 games; a score of at least 7½ would win the world championship. If the score is equal after 14 games, tiebreak games with faster time controls will be played:[36]
A match consisting of 4 rapid games with 25 minutes per side and a 10-second increment starting with move 1 will be played. If a player scores 2½ points or more, he would win the championship.
If the score is equal after the rapid portion, a mini-match of two blitz games will be played, with a time control of 5 minutes per side and a 3-second increment starting with move 1. If a player scores 1½ points or more, he would win the championship. If the blitz mini-match is tied, another mini-match with the same conditions will be played to decide the winner of the championship.
If both blitz mini-matches are tied, a single game with a time control of 3 minutes per side and a 2-second increment starting with move 1 will be played, and the winner would win the championship. A drawing of lots shall decide which player plays with the white pieces. If this game is drawn, another blitz game with reversed colours will be played with the same time control, and the winner would win the championship. This process will be repeated until either player wins a game.

One has to wonder if Magnus Carlsen would have made the same mistakes. I doubt it. He tends to be cool under pressure and more consistent overall.
If the match ends in a tie, there is a playoff day this Sunday using rapid time controls. The games are played at 3 PM Kazakhstan time, which is 5 AM Indiana time. I could see myself getting up early to watch the playoff.

Chronos Chess Clock Repair/LCD Repair
https://www.youtube.com/watch?v=4Zw3upjm18o&t=32s
Much to my amazement, this method fixed the display problem on one of my Chronos chess timers. I used my mother's hair dryer. I heated the ribbon cable to the point that it was almost too hot to touch. Then I rubbed my finger across it to make the cable stick better. No more display problems.
I've thrown away at least 3 Chronos clocks in Salt Lake City because they had stopped working. I kept the clocks in the trunk of my car year-round which seemed to ruin them. They are sensitive to heat, cold, and moisture. It is possible that my old clocks were fixable.
These clocks were considered top-of-the-line, were pretty expensive compared to other game timers, and are now collector items because they are not made anymore.

Re: Chess Puzzle - Magnus Carlsen
I usually have a knack for solving mate in 2 chess problems, some of which can be very difficult. I have a technique that I use to find the answer more quickly.
This problem seemed pretty hard. I kept looking at everything that didn't work.
I got it in 6 minutes.
When I first started solving composed puzzles, there were some that took me half an hour to figure out, but I got better at it with practice.

Chat GPT
Talk about Paul Morphy.
Paul Morphy (1837-1884) was an American chess player who is widely regarded as one of the greatest chess players of all time. He was born in New Orleans, Louisiana, and began playing chess at a very young age, learning the game from his father and uncle. Morphy showed an early talent for chess and quickly developed his skills.
In 1857, Morphy traveled to New York to compete in the first American Chess Congress. He won the tournament, defeating several of the best players in the country, including Alexander Beaufort Meek and Louis Paulsen. Following his success in New York, Morphy traveled to Europe to compete against the best chess players in the world.
In Europe, Morphy quickly established himself as a dominant force in chess. He defeated many of the top players of the time, including Adolf Anderssen, the winner of the 1851 London Chess Tournament, and Howard Staunton, the leading English player. Morphy's style of play was aggressive and attacking, and he was known for his brilliant combinations and sacrifices.
Despite his success, Morphy's career was relatively short-lived. He retired from competitive chess at the age of 21 and returned to his law studies in Louisiana. Morphy's retirement from chess was a great loss to the game, and many chess historians speculate about what he might have achieved had he continued to play.
Despite his brief career, Morphy's contributions to chess have been significant. He was one of the first players to emphasize the importance of developing the pieces in the opening, and he introduced several new attacking ideas that are still used by chess players today. Morphy's games continue to be studied and admired by chess players around the world, and he remains one of the most celebrated figures in the history of the game.
Talk about Paul Morphy in the style of Jordan Peterson
Well, Paul Morphy was a fascinating figure, and his story speaks to many of the fundamental aspects of human nature that I often discuss in my work.
Morphy was a brilliant chess player, and his success can be attributed in part to his extraordinary talent and dedication. But I believe that there were deeper psychological factors at play that contributed to his greatness.
Morphy was deeply curious and passionate about the game of chess, and he devoted himself to mastering its intricacies and strategies. He was also a natural risk-taker, unafraid to take bold moves and make sacrifices in pursuit of victory.
But I think what really sets Morphy apart is his ability to channel his emotions and intuition into his play. He was known for his aggressive style, which often involved sacrificing pieces in order to gain an advantage. This kind of bold, intuitive play requires a deep understanding of oneself and one's emotions, as well as the ability to channel those emotions into productive action.
Morphy's story also illustrates the importance of pursuing one's passions, even in the face of opposition or criticism. Morphy's family did not always support his interest in chess, and he faced significant challenges and setbacks throughout his career. But he remained committed to his love of the game, and ultimately achieved great success as a result.
In conclusion, Paul Morphy's life and career exemplify many of the themes that I often explore in my work - the importance of pursuing one's passions, the power of intuition and emotion, and the role of risk-taking and determination in achieving greatness. He was a remarkable figure who continues to inspire and fascinate people to this day.
Was Paul Morphy crazy?
There is no evidence to suggest that Paul Morphy was clinically insane or suffering from any kind of mental illness. While he did exhibit some eccentricities in his behavior, such as his tendency to pace and mutter to himself during games, these are not necessarily indicators of mental illness.
Some historians have suggested that Morphy may have suffered from obsessive-compulsive disorder (OCD), based on his reported need to touch each chess piece before making a move. However, this is purely speculative and there is no way to know for sure.
It's worth noting that Morphy lived in a time when mental illness was not well understood, and people with mental health issues were often stigmatized or marginalized. As a result, it's possible that Morphy's behavior may have been misinterpreted or unfairly judged by his contemporaries.
In any case, while Morphy was certainly a unique and sometimes eccentric figure, there is no reason to believe that he was insane or suffering from any kind of mental illness. Instead, he was a brilliant and passionate chess player who dedicated his life to mastering the game that he loved.
Was Bobby Fischer crazy?
Bobby Fischer was a legendary American chess player who achieved international fame for his historic victory over Boris Spassky in the 1972 World Chess Championship. Fischer's behavior in his later years was often erratic and controversial, leading some people to speculate that he may have been mentally ill.
It's difficult to say for certain whether or not Fischer was clinically insane or suffered from a mental illness, as he was never formally diagnosed. However, he did exhibit many symptoms of mental illness, including paranoia, delusions, and extreme mood swings.
Fischer's behavior became increasingly erratic in the years following his victory over Spassky, and he became known for his controversial public statements and bizarre behavior. He also became increasingly reclusive and isolated, cutting off contact with many of his friends and family members.
Some experts have suggested that Fischer may have suffered from a form of schizophrenia or bipolar disorder, which could explain his erratic behavior and extreme moods. However, this is purely speculative, and without a formal diagnosis, it's impossible to know for sure.
In any case, it's clear that Fischer's later years were marked by significant mental and emotional turmoil. While his contributions to the game of chess remain significant, it's important to remember that he was a complex and troubled individual who struggled with a range of personal and psychological challenges.

Draw by resignation?
Draw by resignation: Under FIDE Laws, a game is drawn if a player resigns and no sequence of legal moves would allow the opponent to checkmate that player.
5.1.2 The game is lost by the player who declares he/she resigns (this immediately ends the game), unless the position is such that the opponent cannot checkmate the player's king by any possible series of legal moves. In this case the result of the game is a draw.
Apparently, this is a new rule. Common practice would be that the player who resigns loses the game regardless.
This doesn't seem to be part of the U.S. Chess Federation rules, meaning that this rule would only apply to international tournaments.

The Woodpecker Method
https://zwischenzug.substack.com/p/the-woodpecker-method
Before Michael De La Maza published his book "Rapid Chess Improvement", he wrote an article by the same name. Before he published this article, he sent it to me to get my suggestions, because I had a website since around 1996 that advocated the same idea. I believed in doing a large number of tactical problems repeatedly to build pattern recognition. When I did this myself, I saw my rating go from 1800 to 2000.
I can't guarantee that this is the best way to improve one's chess tactics. For myself, my goal was to be able to see the vast majority of 1, 2, and even 3-move combinations instantly. However, doing new puzzles might also be good.
My website hasn't changed much since I first published it. It is dated. At that time, the Internet (World Wide Web) was relatively new, and most people didn't have access to it. Chess Life gave me an "award" for the website, but there weren't many chess websites at the time.

My website hasn't changed much since I first published it. It is dated. At that time, the Internet (World Wide Web) was relatively new, and most people didn't have access to it. Chess Life gave me an "award" for the website, but there weren't many chess websites at the time.
Chess Game against Novag Super Constellation level 1.
This game is interesting because I don't normally beat level 1. Here I blew the endgame, but so did the computer. The 39-year-old chess computer can't see deep enough to play the endgame correctly.

Even the infinite level takes 12 hours to see the draw with a 10 ply search after 33... h5 34. Rc7.

The Super Constellation fails at deep calculation. It sees shallow tactics very well, which is where its strength comes from, so it appears to be pretty strong at speed chess. It is not clear if the computer can calculate three-fold repetition or any repetition on a deep search because the 8-bit hardware limitations would make this check very inefficient. This might be the reason the computer fails in the above position. The computer would not normally search deep enough to see a three-fold repetition anyway.
Other than missing the draw, the Super Constellation played a very solid game. According to Stockfish, I made no mistakes in this game. This is what it takes because the computer will punish small errors.

Apparently, Magnus Carlsen is taking a year-long break from playing in Over The Board tournaments.
He mentions hating having to travel so much.

My Goal: Reaching a 1000 Rating! #chess #shorts

I shouldn't talk since I am an Expert, but this is the kind of combo that takes me a couple of seconds to see.
I believe that it is fairly easy to get to 1300. A person just needs to be able to see most 2-move combos. There might be a few unusual 2-move combos that a 1300 would not see, but being able to see most 2-move combos would make a person 1200 to 1300. I think that being able to see most 3 move combos would make a person 1400 to 1500.
A couple of weeks ago I was proud of myself for seeing a six-move combo in a speed game, but I made the same mistake that many players make where I didn't calculate the next move. After winning my opponent's rook I realized that he could trap my queen. My lower-rated opponent didn't see it, but he could have been winning.

Stockfish 15.1 - Stockfish
The Stockfish chess engine has switched to a new evaluation method similar to what Alpha Zero or Lela Chess uses. It is no longer about material but winning chances, which is dependent upon an AI that can train itself. This method allowed the program Alpha Go to beat the best Go players, which was previously thought to be impossible.
"New evaluation
This release also introduces a new convention for the evaluation that is reported by search. An evaluation of +1 is now no longer tied to the value of one pawn, but to the likelihood of winning the game. With a +1 evaluation, Stockfish has now a 50% chance of winning the game against an equally strong opponent. This convention scales down evaluations a bit compared to Stockfish 15 and allows for consistent evaluations in the future."
