My Strong Chess Engines



Today, more than 20 years since Deep Blue defeated Kasparov, chess engines have even become a lot stronger and increase in playing strength each year. This is partly due to the increase in processing power that enables calculations to be made to even greater depths in a given time.

In addition, programming techniques have improved enabling the engines to be more selective in the lines that they analyze and to acquire a better positional understanding. Even better than the World Chess Champion Magnus Carlsen. Nowadays, there is no human player who can beat one of the best chess engines.


Stockfish is an open-source UCI chess engine available for various desktop and mobile platforms. It is developed by Marco Costalba, Joona Kiiski, Gary Linscott, and Tord Romstad, with many contributions from a community of open source developers.


Today, many chess players spend a lot of time working with computers. Any ambitious chess player can and should download at least one strong chess engine. Chess engines evolved to one of the most vital chess training tools.


Having a chess engine gives you the possibility to have a Super-GM at home who will give you his evaluation and the best move in any position you want.


Although there is a great variety of chess engines with different styles and strong points (and weak points also), most of them play better than any human player, so there is no better advice to take! And some of them are even free!


In essence, chess engines are a great chess training tool to have. If they are used correctly, they can help any chess player to improve. If not, the extensive use of chess engines can result in the stagnation of your playing ability and you might stop improving.


Therefore, firstly, we want to caution you a little against the topic of chess engines in the following article. Subsequently, we will present you the three best and latest chess engines which are available on the market.


Such a position might well have received a +2.00 evaluation not very long ago. However, thanks to the continuing advancements in chess engines, Stockfish 13 now rates this position even no matter which side is to move.


As the fortress position has only five pieces (where pawns are considered pieces), a tablebase with this position has been available for many years. Any chess engine that utilizes tablebases would instantly evaluate the position to a draw because it only needs to check the tablebase. No analysis is required.


A lot of nonsense is spoken about computer chess engines. I am confident that the very best human chess players would never beat Stockfish 14 set at maximum strength. To claim otherwise is disingenuous. A novice chess player using stockfish 14 can easily draw or beat the best human players who are not using chess engines. Why pretend otherwise?


thanks alot sir thi article deals with the many interesting facts and topics abuout engine i am sure that any of the chess players can learn a lot about that and elimainate the bad habits that is because of enginges thanks alot sir yo uare the bst


Chessify is the perfect option if you want to be able to work with the strongest chess engines, have premium service, and don't like settling for the second-best. I believe the Chessify Cloud service is great for professional or aspiring players as well as the chess fanatics eager to analyze with the hardware that only the very best allow themselves to use.


I can confidently say that Chessify is one of the tools that revived my career after a rough patch. I use their servers every day and enjoy playing around with different setups for Artificial intelligence engines. Knowing that the Chessify team is within a call or an email that gets answered immediately I can safely concentrate on my chess journey.


So now that we understand that a suggested variation presented by a chess engine after sixty seconds is better than a variation suggested after two seconds, we can move on to the more important matter at hand: how to make your chess engine stronger.


Claude Shannon calculated that there are around 10^120 possible games of chess in his seminal paper Programming a Computer for Playing Chess in 1950. In Rage Against the Machines, Nate Silver quotes Diego Rasskin-Gutman, who said:


Given unlimited resources, it actually doesn't take many lines of code to calculate every legal variation of chess. Here, the Python package python-chess is used for board representation and legal move generation.


The evaluation of a chess board is one of the things that's kept me interested in chess engines. Evaluation rules are easy to add and take away. I refactored the code from Go to Python to be able to prototype different rules faster.


At first the premise seems absurd - the computer engine relies much more on brute-force search (Shannon's Type A Strategy) over selecting a few strong lines with heuristics (Type B Strategy). But can the process of creating and testing the evaluation function actually help my human chess playing at all? For example, I learned from Chess Programming Wiki that a bishop pair gives a small bonus roughly half a pawn, knights do better than bishops when there are many pawns on the board, and that certain pieces are stronger in general on certain squares. By testing out what the computer values, perhaps these ideas (such as checks, captures, threats) can transfer a little to real-world play.


I wrote an engine a while back. I would call myself a "competent inactive chess player," defining that as in the uncomfortable divide where playing people who aren't active chess players is so easy that it isn't even sportsmanlike, but playing against active players is humbling. For a class, I had to write a chess engine. From my experience, I do not believe you can learn much about chess this way.


When building up an engine, you spend much of your time teaching it not to do monumentally stupid moves. In my class, I was the only person who wrote an engine that didn't fall victim to the 4-move checkmate. My classmates were amazed at my ability to not hang pieces. Getting my chess program to out-perform an elementary student with 1 month of Chess under their belt was quite the challenge, and it certainly didn't teach me anything about the game. It taught me a great deal about game theory (which was, after all, the purpose of my course). It taught me about bitboards and perfect hashes, neither of which are used by humans during play.


If you are a beginner, then yeah it would help. As you wrote, "bishop pair gives a small bonus roughly half a pawn, knights do better than bishops when there are many pawns on the board, and that certain pieces are stronger in general on certain squares" - these are nontrivial pieces of chess knowledge that you can learn from writing an engine.


Past the beginner level though, it's not likely to be helpful - especially if you use NNs or NNUEs like the best modern engines do, in which case all the chess knowledge in the first paragraph don't matter anyway.


No. Humans and engines play chess in completely different ways. Being able to conclude that the evaluation function bonus for the bishop pair should be 0.3 rather than 0.2 will have pretty much no impact on your actual chess skill. People just don't think like that.


Even if there was a benefit to your chess by writing the code for an engine, there are definitely more effective training methods, like tactics, analysis, practice games and so on. You can learn the ideas you mention from a strategy book in a more complete way by watching illustrative examples and analyzing those games.


It is the other way around. Being a strong chess player allows you to write a good evaluation function.The evaluation functions of strong chess engines are known, and the principles they encapsulate are already taught to chess players in books and other means.


For example, there are countless videos, book chapters, etc. on the power of the bishop pair, similarly, it is well known to even weak players that bishops generally strive in open and knights in closed positions (this is why knights are better when there are more pawns).You would learn all that while reading chess books, without needing all the overhead of engine programming.


Yes, engine programming can make you aware of certain important concepts, but it won't necessarily help you to apply and understand them.On the other hand, the best way to improve in chess is to devote time to studying chess (not to fix annoying C++ bugs, so you would even have an opportunity cost if your goal was solely to improve in chess).


All that being said, I would like to encourage you to build your own engine.It is far more impressive to anyone if you can build a chess engine than if you have gained some Elo instead.Knowing how to program is also far more valuable in today's world and will bestow much more transfer use upon your life.


Nowadays, programming a chess engine is not as difficult as it used to be in the end of the 20th century, mainly thanks to the huge technological leaps that took place ever since. There are tens of chess engines today, some written by a single person, some written by teams of programmers.


When a chess engine presents a numerical score for a given position, it assigns positive values to indicate an advantage for white, and a negative sign to indicate an advantage for black. For example, +0.56 means white is up by 0.56 of a pawn or 56 centipawns, if you will. a value of 0 means equality.


DecodeChess explains the moves of Stockfish, which is considered to be one of the top chess engines in the world. It won the 2018 computer chess championship on chess.com and appears on the analysis boards of leading chess websites, including lichess, chess.com and more.


When I had to decide what software to use for my chess environment I did quite a bit of research on what GrandMasters get. I am software engineer (is my full-time job) and have a few insights to share also on how to set up your chess software environment.
