What About Chess Engines? Part 2

 In What About Chess Engines Part 1 we saw how powerful chess engines can give deep analysis of a complex position. This tool is helpful to point out what moves are strong, but this leaves you to figure out why and the ideas behind each move. This is where Decode Chess with it's AI (Artificial Intelligence) can be a real help. Using Stockfish running on it's servers Decode can analyze a game or position and give a lot of explanations as to the why and ideas behind each move.

I put in our position from Part 1 and let Decode "think" on it. The summery tab came back with a lot of good info. Explaining why Stockfish NNUE (what is NNUE) likes the idea of castling in this position. What are the forces at play. I like the graphics on the board too.

  Clicking on the + sign next to "How to find the best move. +" yields additional information. What is the Idea? the Problem? the Solution? It's all spelled out in a more human way of thinking.

If you click the tabs across the top you can learn even more. What is the role of the pieces involved in this continuation? Again the graphic is very well done.

The next tab deals with the Threats in the position. Before Black makes his move...

... and after.

So besides the best move. What are some other good moves? The "Good Moves" tab shows us.

Next are the "Plans". What is Black wanting to do? What is the problem? and the solution.

Finally the Concepts tab.

Here after expanding the Black uses the open d file concept. We see my original idea Nb6 wasn't totally without merit. I hope you enjoyed this deep dive into chess engines and how they can be used. I'd love to hear your thoughts if you would care to leave feedback below.

What About Chess Engines? Part 1

 Is one computer engine better than another? Should I let it "think" for a longer time? What about cloud computer engines? I decided to run some tests. First I setup SCID vs PC with a position I've been trying to figure out. It's a middle game with a lot going on. Not easy to say what is best. Below is the FEN (Forsyth-Edwards Notation) of the position. In case you want to do some tests yourself.

r2qk2r/1bpnppb1/p2p1np1/1p4Np/3PP2P/2N1BP2/PPPQ2P1/2KR1B1R b kq - 5 10

I thought Nb6 was interesting. It had only been played twice in my database of over 5 million games. Black appeared to be the winner of both games by the graph. I ran Stockfish for 20 seconds. Stockfish liked the number one entry from the database e6. With Nh7 as it's second choice which comes in at number 10 on the database list.

So I let the engine run while I did some errands. When I came back Stockfish had looked 36 moves ahead. Still e6 was it's favorite.

Well what would Komodo think? With only 20 seconds to "think" Komodo liked O-O with e6 coming in second. Note Komodo 12 only looked 18 moves ahead in 20 seconds compared to Stockfish's 27 moves.

Next I loaded the position into the Fritz 16 GUI. Again I let Fritz 16 analyze for 20 seconds. It looked 27 moves deep and liked the castle move O-O. While I was setting up the cloud engines were researching the position. Over 20 seconds but less than a minute I think. This time Stockfish looked 42 moves deep and again liked e6.

So I stepped through the database and decided e6 really is the best continuation. So back to the questions. 

Is one computer engine better than another? Yes Stockfish is King, but it never hurts to research with other engines. Should I let it "think" for a longer time? Yes if the position is complex enough that the engines don't all agree. What about cloud computer engines? They are more powerful. It may not always matter but it's worth consulting them.

Chess Websites

 Here are the biggest most important chess websites. I will give the cost for a one year full membership where applicable. Most have other purchase options. They are listed in no particular order, and I do not claim that this list are the only sites to be recommended.

Pay To Play:

Chess.com : It's the biggest. To enjoy all the features you will have to pay. Still there is a lot. Matches of just about every kind. Tournaments, news, puzzles, problems, computer play, bots, articles, and lessons. If it has to do with chess they probably have it. Currently $99 for a year of full access.

Chess 24 : Another big site with lots to offer. Again to have full access you will have to buy a membership. 1 year membership at the time of this writing $149.99.

Internet Chess Club : AKA ICC Has been around a long time in internet years. Another big site with a lot of content. USCF holds rated tournaments through this site. 1 year $69.95.

Free Chess Sites:

Play Chess : By Chessbase. This used to be a paid site but now appears to be free to non professionals. Chessbase is the professional chess database software company. Also home to Fritz, and other chess engines. Certainly worth checking out.

FICS Free Internet Chess Server : Before there were chess websites you could download an interface and play over a chess server. Both the ICC above and FICS date back to those days. You can still download a GUI Graphical User Interface and play that way. Also you can play through your browser. It's free. "We do it for the game not for the money". Appears to be their moto.

Lichess : Last but not least is Lichess.org. "lichess.org is a free/libre, open-source chess server powered by volunteers and donations." The name is derived from live/light/libre chess. It is another full featured website with game to play, watch, or analyze, videos, etc. I love the look and feel. The analysis graphics are excellent. It compares well against the paid sites and it's free.

Others: This category I could use some help filling if you know of a site to recommend please leave a note in the comments.

Decode Chess : Using Artificial Intelligence AI to analyze your games and explain why a move is good or bad. If you haven't tried it you really should. I find it interesting.

Chessable : A chess teaching platform. Using advanced teaching methods. You can use many free courses and samples and purchase full blown chess lessons.

Bill Wall's : A huge research and links site. Looking for pgn game collections, and books, this is the first site to look at.

Well that's all for now. Let me know what you think. Leave a comment / suggestion.

Study Chess Books On Your Computer

 Study From An ebook!

I like books I really do. However following variations and getting back to the main line leaves me scratching my head. I like to get the book in pgn and ebook formats. Then use readers to follow and study.

Here is my desk setup.

On my laptop is the Kindle reader. The book in this case is "The Modern Defence move by move".

The big second screen is showing the book in pgn format. Using SCID vs PC I can step through the moves and variations and jump back to the main line along with the flow of the book.

If you look closely you will see the text matches the book. With the advantage of comparing the book with a huge database of games, and analysis by an engine (Stockfish 14.1 in this example). I hope this gives you some ideas that will help you study chess from a book / ebook / pgn file.

The $1000 Game

I was playing the last round of the 2019 Southern Class. If I win it would put me in 1st place Class C. The prize was $1000. We both made multiple mistakes in the last moves of the game.
