Black Hangs On

I've gone deep down a rabbit hole on this one.  

It gets way deep, but it illustrates fighting back in a potentially losing position.  I think that this is instructive.

I got started down this path because the computer said that I made the wrong move.  However, I didn't realize just how deep the analysis would get.

Re: Improve Your Chess Tactics

I have uploaded to the website at least a couple of dozen changes to the tactics problems.   Many of these are cosmetic, but I have also fixed a few errors.  

I added one or two new problems.

White to Play

This would seem to be too deep for mere mortals, but not for a world champion.  This was played in 1895, one year after Steinitz lost the world championship to Lasker.

https://positionalanalysis.blogspot.com/2025/10/white-to-play_30.html

I could see Hikaru Nakamura playing something like this.  The weird thing is that he would see it all the way through.

BTW, decades ago I watched Hikaru Nakamura as a child playing in a blitz tournament in Las Vegas.  He beat a grandmaster.

GM Daniel Naroditsky

I have been waiting to hear the cause of death of 29 year old Grandmaster Daniel Naroditsky.  He was a popular chess Youtuber having made hundreds of videos.

The police said that they were investing his death as a possible suicide or drug overdose.  His family was requesting privacy, so I am not sure if we will hear the official cause of death.

The night before Naroditsky died, he was playing a marathon session almost till morning. He may have been streaming his games at the time.  Reportedly, some of his friends tried to intervene, saying that he was playing himself to exhaustion.  He said that he was fine.

I looked at his history on chess.com.  He lost his last 6 games, which is when he probably decided to stop playing.  In his last game he hung a rook before resigning, which is rare for a Grandmaster.  It probably shows that he was exhausted.  Hanging a rook is an unfortunate way to end one's chess career.

Former world champion Vladimir Kramnik has shown paranoid levels of suspicion about online cheating.  Although online cheating is a problem, Kramnik has accused way more people than what would be reasonable.  He has accused some of the world's best players of cheating.  In particular, he slandered Daniel Naroditsky for over a year in a way that was harmful and Naroditsky said caused him distress.  Many people believed the former world champion.

Although we still don't know the cause of death for Daniel Naroditsky, the world chess federation (FIDE) is considering sanctions against Kramnik for what they perceive as improper behavior.  They even tried to warn Kramnik that he was getting out of line.

The Type of Chess Problem I Don't Like

White to play and mate in 2



Solution...
































































I don't particularly like problems with castling as the solution. They feel like trick problems. I was thinking that it was impossible until I realized that White could castle.

There is no reasonable way that you would reach this position in a real game.

Chess for Babies?


I doubt that babies are capable of abstract thinking.  (BTW, the games on this video are really interesting.)

I remember that at a young age, maybe 9 or 10, I was fascinated with any kind of grid, like a tiled surface.  I would imagine a ball traveling along a diagonal and bouncing off an edge at a right angle and continuing on bouncing off other edges.  This was long before ball and paddle video games were invented that did essentially the same thing.  

My point is that humans have a natural fascination with geometric patterns and chess is a geometric game.

A World Champion designed this, white to move and win!

https://www.youtube.com/watch?v=1Jc0hDxV_Gs

I would call this a master level endgame.  These corresponding-square problems arise when the king is trying to advance on one of two sides, and the enemy king is trying to guard both sides.  So the two kings do a dance to out maneuver the other.

It was obvious to me that this was a classic corresponding-squares problem. Starting from the left, the Black king must be on b6 when the White king is on c4. If the Black king is on a6 then he is too far left to prevent the White king from marching to h5. From this we obtain five more corresponding squares: the White squares d3, e3, f3, g3, and h4 correspond, respectively, to the Black squares c7, d7 e7, f6, and g6. If it is Black's turn when both kings occupy corresponding squares, Black is forced out of position. 

From that I knew White would need to triangulate at some point, but the actual triangulation move was not obvious to me. Maybe in a real game I would stumble on the correct move. 

The key idea is that after 1. Kb2 Kb8 Black wants to move to a corresponding square after White does. White also wants to move to a corresponding square after Black does. 

Note that 1... Kb7 loses to 2. Kc3 because both players attack two corresponding squares and it is Black who has to move first. This is tricky to see. 

(I'm still trying to wrap my brain around 1. Kb3 Ka7 draws.  After 2.Kc3 Kb7 we have the situation described above where both players attack the same two corresponding squares, but it is White's turn.  Can't White still try to triangulate?  Apparently not.   I need to look at this further.)


So where's the triangulation? 

2. Kc2 Kc8 
(2... Kb7 3. Kc3 is still winning.) 

3. Kd2 Kd8 
Black stays in range of b6. 

4. Kc3 Kc7 
Still keeping in range of b6. 

5. Kd3 
This is the triangulation because Black must still guard b6. Both kings are on their corresponding squares and it is Black's turn 

5... Kd7 
(5... Kb6 6. Ke3 wins on the kingside.) 

6. Kc4.

Rook and Pawn Ending

I did a detailed analysis of this ending from one of my games.  This is how I have learned most of my endings.  🙂

Some of the lines are complicated.  

With propper play, White can barely hold the draw.

Little Big Shots: Chess champion Emma Cheng

40% of chess players on chess.com are rated below 480???

https://www.youtube.com/shorts/FQH-GGQPyy8

The ratings used to be different.  I remember having a conversation with a Class A friend 35 yeas ago, who said that anything below 1200 was meaningless, because he reasoned how can you be worse than bad?

However, there were a great many more children who participated in tournaments after that.  This brought the average down by a huge amount.  Kids who had no real concept of how to play chess properly were competing for rating points.

I've talked to adults who have very low ratings on chess.com, like in the 400  to 500 range.  If they are able to find people on their level to play chess with, then more power to them.

It seems like Magnus was being generous.  I see a rating of 800 as a base level competency.   It is really not hard to get 1200 or 1300.  You just have to not make simple mistakes.  Any form of regular tactics study would get a person to that level.

My USCF rating history graph

This is an interesting graph of my chess rating. The records only go back to 1991.

https://www.uschess.org/datapage/ratings_graph.php?memid=11080847

I first crossed the 1800 rating mark in 1985. However, I was frustrated by my lack of progress until 1988, when I moved near Purdue University. There, I started playing regularly with the Purdue players and running many tournaments, which helped me to improve.

Around 1990, I reached my peak rating of 2079.

After moving to Utah in 1993, my rating dropped back to 1800.  Part of that decline was due to the stress of starting a new job.  Additionally, in the 1990s, there was a perception that Utah players were underrated. This was largely due to the state's relative isolation—traveling to out-of-state tournaments required significant effort, which meant there was less mixing of rating points between regions. I used to drive 420 miles each year to play in the National Open in Las Vegas, which I attended for 12 or 13 consecutive years.

The 1990s also saw deliberate rating deflation by the USCF, following concerns about rating inflation during the 1980s. The USCF aimed to bring its ratings more in line with international ratings, which were generally lower. However, the deflation was so unpopular that the USCF eventually revised its rating system.

Around the year 2000, I set a goal to raise my rating—possibly to master level—by memorizing 200 opening lines. I originally planned to accomplish this in 200 days, but it ended up taking about 400. Then I played in a five-round state championship, and all of my games went out of book by move 5. As a result, I shifted my focus to tactics training. I put a great deal of effort into improving my tactical skills, and my rating began to rise.

I crossed back over 2000 shortly before moving back to Indiana in 2015. In the years leading up to that move, I had several notable tournament results, including winning or tying the Senior Championship four times, winning the state G/60 Championship, and claiming the Expert trophy in the Class Championship.

Taliban Ban on Chess

 "They shouted at us, they grabbed our chess sets and pieces and they beat up two of my friends," he recalled. One of his friends tried to challenge the men, who work for the ministry for the prevention of vice and promotion of virtue, which upholds the Taliban's hardline interpretation of Islam, as fleshed out in its recent morality laws. He says one of them told him: "Playing chess is forbidden. Buying a chess set is forbidden. Even watching it — is forbidden."

"In short," Hassanzadeh said in a telephone interview, "this healthy and harmless entertainment was snatched away from us."

Update to my online chess lessons

For those who might be interested, I have updated my online chess lessons.  

I have improved the order of the posts and grouped some items by openings.

The Future of Road to GM


@john2001plus
0 seconds ago
Levy,

At 64, soon to be 65, I find that I have a different perspective on things.

I play chess for fun and to learn. I am always learning. If it ever felt like a job, I wouldn't find it worth playing. After all, jobs aren't supposed to be fun.

At my age, I deal with enough minor physical issues that attending tournaments feels like unnecessary work and a time-consuming burden. Unless I were to make significant progress, I have nothing to prove by going to a tournament. I could spend an entire day or weekend at a tournament, possibly gaining 8 rating points, or losing more than that. What would I really accomplish?

Tournaments used to be fun, but they're better suited for younger people with more energy to spare. I haven't given up on tournaments completely, but I'm waiting for the right time.

When I returned to my home state after 22 years, I noticed that many of the players I used to compete against were still playing in tournaments, and their ratings were exactly the same as when I left. My rating had fluctuated quite a bit, but ultimately ended up around the same level. It seemed like we were all chasing a higher rating for 22 years—and making no real progress. That's a lot of effort for no return.

People often go to tournaments thinking they're the key to increasing their rating. But what really matters is whether a person has the skill to reach their goal. Either they have the skill, or they don't. If someone is GM-level, the title will eventually come.

Chess is a game, and like any skill, it can be improved through practice. Some people become exceptional at video games after practicing for hundreds or even thousands of hours. So, I have a theory that I can improve by practicing against the computer and analyzing my games.

I'll let you know if it works.

Best wishes,

John Coffey

Rod Serling's Greatest Obsession (William Windom)

The episode starred Wiliam Windom, a character actor who played supporting characters on many old shows.

He is maybe most famous for a Star Trek role...

Sicilian Defense: Black to Play

Steve,

You might find this interesting.   I wanted to know which line the computer regards as absolutely the best...

https://sicilianopening.blogspot.com/2025/01/black-to-play_27.html

The computer chose either 6. Be3 or 6. e3 following up with 6... e5, which seems counterintuitive. I assume that the Najdorf variation with 6. Bg5 e6 is more common.

These 70-py searches take days to complete.  Often there isn't much difference between 70-ply and 40-ply, but sometimes they are different.  

In the middle game and endgame, there isn't much difference between 30-ply and 40-ply searches, but the opening choices are often different.
