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.

Favorite Video Sources

 Chess Videos

These are not in any order. Read the brief description to determine if you want to view the material.

Hanging Pawns on YouTube covers all facets of the game. I find his delivery pleasant and understandable. He gets right to the point. So be ready to pause and review.


Anna Rudolf is very entertaining. She branches into other areas but her chess videos are both instructive and entertaining. 

Krishna Prem for beginners openings. He has other videos but his coverage of openings is what I like. he gives the basic ideas and main moves.

agadmator's Chess Channel a lot of chess here. Coverage of events as well as study material.

Chess.com has instructional videos, news, and game reviews. Plus videos from other producers.

I'm just getting started. I'll be editing this list and adding videos. If you have a favorite please share it in the comments or send me a message.

Here are some that were shared with me on Chess.com by Dr_Risiko. I will have something to say about each one as I have time to check them out. Let me just say that as you look for help with your game or entertainment. Take a quick look at one of their videos. If you don't care for the delivery or can't understand the presenter you are not going to gain much from watching that persons videos. The good news is there are plenty out there so keep looking.

GothamChess IM Levy Rozman's Youtube channel covers a lot of topics. From exposing cheaters, to analyzing top games in the news, to playing various bots. It's entertainment with some learning thrown in.

GM Benjamin Finegold A lot of game analysis and lessons.  

chessbrah's A couple of masters with a variety of content.  

John Bartholomew Chess IM John B. Again a lot of learning here. The main thing is for you to take a look at each of these and see what you want and like.

Rosen Chess IM Eric Rosen. The formula is consistent. Lessons and analysis of top games.

Jonathan Schrantz A chess teacher out of St. Louis Missouri. Lots of lessons here.

I hope you will find two or three here that you enjoy. If you have a channel you want to share leave a comment below.

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.

How I Installed Chess.com on Amazon Fire 7 Tablet



First you need to change a setting on the tablet. Goto Settings (swipe down from the top and tap the little gear) - Security & Privacy - and turn on "Apps from Unknown Sources".

Next you need the Android install file called an apk file. To get this you can install the Chrome browser app "APK downloader" in the Chrome webstore.

https://chrome.google.com/webstore/search/apk%20downloader?utm_source=chrome-ntp-icon&_category=extensions

It will generate a QR code you can scan into your tablet.

Or you can skip this step and scan the one below.


I used the Kindle app "QR & Barcode Scanner". By Gamma Play.com As soon as it finishes the option to open / run the file will appear for a few seconds. Click and install / open the file. If you miss it you can start over or go find the file on your device and run it from there. In the download folder. When it opens input your user name and password for Chess.com and your setup is complete.
