Chess engines are a great tool to have. Whether they are used for analyzing games, accurately converting a large advantage into a win, studying openings, or watching cyber chess warfare, if they are used correctly, they tin help whatever chess player improve.

Any avid chess player can and should download at least i strong chess engine. However, at that place are thousands of engines out there and not all of them are created equal. Some of them have a fairly good rating on diverse chess engine rating lists, simply they don't function well. Some take diverse issues such as the disability to set search depth, searches longer than the set fourth dimension limit, or crashes every now so.

This can be a hurting, although most engines that accept these issues are costless for anyone to download. To avoid this potential frustration, I've decided to make a list of the 5 best free chess engines. These engines all follow the Universal Chess Interface protocol (UCI for curt), and tin be used in any UCI-compatible chess plan.

All of these engines are 100% functional and have quite a few configurations to play with. They are also all extremely strong, although some tin be set to play at a more human level, too. Please notation that the rating given to these UCI chess engines aren't mine, merely I get them from a 3rd-political party source, which tests hundreds of chess engines and employ a rating to them. The link to a higher place will accept you to the rating list I used for this article.

Okay, I've blabbered around long plenty! Let's continue to see what some of the best gratuitous chess engines are.

The Rating List I've Used

Computer Chess Rating List
As I said, this site tests chess engines, and gives them a rating co-ordinate to how well they practice. While the site's ratings don't match up with FIDE'southward ratings, it is within the ballpark. I've used the list with 40 minutes per 40 moves time control

1. Stockfish Chess Engine

Rating—3339

Stockfish is the strongest free chess engine. Stockfish vii, the latest version every bit of this moment of writing, has a rating of 3339. Although computer rating lists and official rating lists don't necessarily lucifer upwardly, it is easy to say that Stockfish 7 is well beyond the skill of whatsoever grandmaster. Information technology is also most 40 points above the next all-time chess engine!

The principal co-authors of this engine are Tord Romstad, Marco Costalba, Joona Kiiski, and Gary Linscott. It must exist noted that although these four are the main developers, this engine is open up-sourced and thus was developed past a whole community of people. It is licensed nether GPLv3, which basically means you tin can share to anybody, sell it every bit part of a larger project, and alter the source code, every bit long as you lot either point back to where you lot got it, or supply the original source code.

The Stockfish project is really a fork off of a chess engine chosen Glaurung, which is also open-sourced. People gradually started moving to stockfish, until finally Glaurung was abandoned altogether. It is interesting to note that the Glaurung chess engine'southward rating is 2902, so Stockfish has improved upon its predecessor past 430 rating points.

Stockfish has several interesting configurations; the near noticeable in my opinion is the power to calibration down the skill level, so an average human can beat out it. Information technology has 21 different playing levels, and at level 0, although I have to think, I tin can beat it.

Another configuration that defenseless my eye is antipathy. This setting is to brand it play more risky moves. A setting of zero is default and considered neutral, a positive number upwardly to 100 is more aggressive setting, and a setting of beneath zero upward to -100, it will play for a draw.

While Stockfish is undeniably a potent engine, it is not the strongest. There is 1 engine that is stronger than stockfish according to most rating lists.

2. Komodo Chess Engine (Latest Gratuitous Version)

Rating—3296

Komodo chess engine is actually the strongest chess engine in the globe. The reason why it isn't start identify in the list is because the latest version isn't gratis. The virtually recent version of this engine is Komodo ten.1, which costs $59.96. This version has a current rating of 3379, which is twoscore points higher up its "archenemy," Stockfish.

Still, with every new version of Komodo that is unveiled, there also becomes a past version available for free. Currently, Komodo 8 is bachelor without charge, and this version has a rating of 3296. The free version is nearly 40 points below Stockfish 7 and eighty points below Komodo ten.one. So even with Komodo 8, you're going to have a world-class chess engine.

The thing I wish Komodo would take just doesn't is a setting to weaken its play. This is true for all versions. It is a minor inconvenience though because I mostly use UCI chess engines for game assay, and if I desire to, I can still limit its skill by search depth, which when ready to ane ply, plays quite stupidly.

Komodo 8 does have a configuration to command its aggressiveness, called draw score. The default setting is -7, and if you set it lower, (i.e. -15) information technology will play more aggressively, and if higher, it will attempt to play for a describe more often.

And then, although the gratis Komodo chess engine isn't quite as strong as Stockfish seven, I tin't think of a reason why one wouldn't want to take fourth dimension and download the chess engine. In fact, I bought the engine back when it was the latest and the greatest, and although it was a while back, it's however among the strongest.

Andscacs Logo

3. Andscacs

Rating—3211

The Andscacs chess engine was first released in September of 2013. Since then, it'south merely grown in strength. Its current release, Andscacs 0.872, has a rating of 3211 according to CCRL and has participated in phase 3 of season 9, where information technology came in 5^th place.

The creator of this chess engine, Daniel José Queraltó, lives in the state Principality of andorra. Hence the name of the engine, Andscacs, "And" for his land, "scacs" for the Catalan word escacs, meaning chess. Daniel got his inspiration for creating this chess engine from a variety of open-source engines such every bit Stockfish and Gull.

Unfortunately, this chess engine is no longer available for download. That said this commodity is long overdue for an update, and I will practise and then very presently.

four. Fire

Rating—3208

Fire is another one of the tiptop costless chess engines. Originally called Firebird, this chess engine is usually among the superlative ten in many rating lists. Information technology's debatable whether Burn down or Andscacs is the better engine since they are inside 10 points difference in the CCRL rating listing.

Information technology originally started out equally an open-source project, but subsequently the code became closed. However, there is a fork off of fire 2.2, which has been rename Firenzina, which is still open-sourced. When the Burn chess engine became airtight, the code was completely rewritten and doesn't contain any code from the chess engine Ippolit, as the original open-source version did.

Burn 4 is available for download at this link. In that location is only a 32 bit and 64 scrap versions for Windows in the .rar file.

5. Houdini Chess Engine (Latest Complimentary Version)

Rating—3197

The Houdini chess engine is a very pop chess engine even though information technology is a distant 3^rd place on nigh chess engine rating lists. Houdini iv is the most recent version and it has a rating of 3255 on CCRL. Information technology is a 3 time champion in the TCEC tournaments, which is considered by many to exist the world computer chess championship. Only Komodo holds as many titles.

Rumor has it that Houdini v will be released for the concluding stages of TCEC season 9. Houdini 4 improved upon its predecessor by approximately 50 elo points. Volition this Houdini 5 have a rating of effectually 3300? We're going to have to look and see. I personally have my doubts, since at the moment I'm writing this, Stage 3 of season 9 is already under way, and at that place'south no sign of Houdini 5 equally of yet.

Whether or non a new version will ever be released, the free Houdini chess engine is besides very strong. With a rating of 3197, Houdini 1.5a is a chess engine that a human will never stand a gamble at winning. What'south more than is that Houdini has an interesting manner of play. Many chess players have remarked that this chess engine has a very romantic style of play, similar to such players like Paul Morphy and Mikhail Tal.

Rybka Chess Logo

Rybka

half-dozen. Rybka Chess Engine (Latest Free Version)

Rating—3024

I know that the Rybka chess engine is fairly outdated. Rybka four, the last release, has a rating of 3160. This is around xxx points lower than the complimentary version of Houdini! However, the latest release is still bachelor for auction on Amazon & Chessbase. On Amazon, the engine costs about $l and on Chessbase information technology costs a whopping $90.75! Even the latest version of Komodo's cheaper!

Thankfully, there'due south a free version too — Rybka 2.3.2a which has a relatively minuscule rating of 3024. And then, why am I recommending this engine as ane that every chess thespian should take? Because of a configuration that I think is quite handy! You can set the rating at which it works. With a range of 1200 to 2400, the lower one sets this rating the more mistakes they brand.

The rating will not friction match up with a Fide rating though, and then don't go into a tournament saying that yous have a rating of 1300 because y'all beat Rybka at that rating. That said, if you lot win a game at 1200, your rating volition likely exist college than this. I have trouble defeating information technology at this level, and my rating on chess.com is effectually 1600!

Sorrowdy on April 24, 2020:

And where is Raubfisch? According my engine tournaments it is the best engine always. And it'south likewise free.

noob on March 10, 2020:

It'southward 2020 and this article makes zero mention of the new Neural Network engines Lc0, Leelenstein, Stoofvlees, all of which are significantly better than every engine above except Stockfish.

Really? on October 27, 2017:

Check your spelling and grammar. Nothing added here beyond a rating list and some nonsense. You can find actual reviews elsewhere online, and links that aren't "hard to detect." A chess "fan," actually? Not a histrion, a fan? lol

ciarli on September 29, 2017:

what about 'demon' engine! I heard that information technology is prohibited because he tin can make whatever move and win once again and is insulting Godmaster way of thinking!

Dr.. Shahinur Islam on August xxx, 2017:

Thank you.. :)

Thomas on October 23, 2016:

Very nice and competent review of the best chess programs - thank you! I wonder, yet, if the new version of Houdini is not fifty-fifty stronger given it's current performance in TCEC Rapid - maybe 100 -150 Elo points over version 4? Anyway - we'll run across in the TCEC Super Final! Best Regards Thomas
