Chess Skill

Chess is a complex game.  One grandmaster said that it is too complicated for any single mind to comprehend completely, which is true, but the human race has made reasonable stab at it.  Thousands of books have been written about the game, and an inexhaustible list of strategies have been developed.

I have been thinking about chess skill.  I wonder if anyone has tried to study all the components of chess skill?  On personal reflection, I think that chess skill can be broken into four parts:

1.  Vision.  This is something I developed at the age of 14, when I realized I could see all the all the moves available on the board at the same time.  Chess vision is the ability to see things instantly that others would have to think about.

2.  Pattern recognition.  This is similar vision, except that chess can create many complex patterns.  Through experience and study, skilled players have developed the ability to recognize these patterns in their games, sometimes almost instantly.

3.  Knowledge.  Many complicated strategies have been worked out about chess, and players have to memorize some of them to compete seriously.  I have spent a great deal of time committing chess strategies to memory.

4.  Understanding.  This is by far the most important.  There are areas of the game that I understand so well that they require almost no thought or effort on my part.  I can play these positions with ease.  There are other areas of the the game where I feel completely ignorant.  For example, sometimes I get into positions that make me uncomfortable because I don't understand them very well.

The reason why understanding is so important is because the more we understand something, the easier it is to learn.  This worked really well for me on my computer studies, because the concepts came easy for me, so it didn't take much effort to learn them.

I think many players try to learn things in chess without fully understanding them.  At times I have been guilty of this.  It can be difficult because chess is a hard to comprehend game.  There are many different areas in chess, each of which can be separate field of knowledge.

So to be a good student at chess, one needs either good coaches or good books that explain the concepts well, and the student needs to make sure that he really understands what it is that he is learning.  The same thing could probably be said about any field of study.

My chess.com rating is up.   My round 5 opponent is listed as having "NM" title.  His last move was an odd blunder.  Mouse slip?

The Bunratty Riesling Gambit

Youtube recommended this video and I took an interest in it:  GM Analysis #13: Williams vs Wells: The Bunratty Riesling Gambit

However, when I analyzed the game with the computer, many of the moves from the game were a little faulty.  GM Williams seems to understand that he was playing a risky gambit line.  Rather than play the most perfect moves, he was going for his plan which he explains really well in the video.

So I think that the game is worth studying.

I am going to base tomorrow's chess lesson at my chess club on this great video

This is my suggested method for studying openings:

1.  Don't play into your opponent's book.  It is better to play something a little unusual than to feel like a deer in the headlights not knowing what to do.  Don't worry if the line you play is the absolute best.  Not even Magnus Carlsen likes to play the absolute best lines.  He is just trying to get to a playable middlegame where he can find a plan.
2.  If you just learn a line from a general opening book then this won't tell you how to play the middle game.
3.  Don't rely too much on computer analysis because that won't tell you how to play the middle game either.
4.  Instead find a chess game that is well explained.  It turns out that youtube is a good source.  There are probably other sources on the internet or books.
5.  Memorize this game.
6.  I also recommend practicing the line from both sides with a friend for at least a month if you can find someone willing to do that.  Maybe play the line up to move 10 or 12.  Don't be afraid to try different ideas.
7.  The first time you play the line against someone who is experienced in the opening, they will play something you don't expect.  First try to see if there is a way you can take advantage of them playing something different.   Then after the game, it is a good time to go the computer or database to see if you can improve upon what you played in the game.  If you repeat this process a few times then you will get better at this opening.  

Also see if you can find games with the moves that your opponent played.  Maybe try to find a game with strong players where your side won, but if there is no commentary then annotate the game yourself with the help of a computer.  It might also help you to show the game to other people.  With this new game, start the process over again.

​Best wishes, 
John​

You might find this instructive.

Trying to analyze with a computer as many of my online games that I have time for.  A few of these teach me important ideas that I missed.

In this particular position, I didn't know how to proceed and I made mostly random moves until I stumbled into a win through no fault of my own.

There was a better way to play this.  It turns out that White can follow a plan of aggressively attacking the kingside with pieces and pawns until the black position crumbles.  


In this particular game, I got more bogged down with analysis than I usually do.  In the web page above, I have placed a link to side variations below the diagram.  One of the side variations also has links to other side variations.

Regardless of how complex the analysis got, the principle of using the pieces and the pawns together to attack the king is a good one.

It is my policy to (mostly) memorize the continuations from these web pages for the winning side.  My goal is to be able to intuitively recognize similar positions in my future games.   It is my belief that if one understands sufficiently the reasons why particular moves are made, then remembering the moves is not that difficult.
