If you are not old enough, you didn't see the days when a world champion could beat dozens of best computer chess programs even in a simul.
In 1997, the equilibrum has shifted in favor of the computers, after Deep Blue has been the first computer to beat a human world champ in a match.
The 6 game match is a historical moment of the human vs machine, so there have been many books & publications & media articles about it.
Let me share two of them, although not very recent, but still interesting to read:
1) @ THE CONVERSATION:
Twenty Years on from Deep Blue vs Kasparov: How A Chess Match Started the Big Data Revolution
2) @ TIME MAGAZINE:
Did Deep Blue Beat Kasparov Because of a System Glitch?
3) @MEDIUM.COM: CONVERSATIONS WITH TYLER COWEN (BONUS PACK):
...and the third, as a bonus, speaks about the future of AI from Kasparov's point of view. Don't forget to read what GK suggests about a match opportunity between Magnus Carlsen and the strongest computer program available (Stockfish?).
Garry Kasparov on AI, Chess and the Future of Creativity
I was still a kid when Deep Blue defeated the indefatigable GK and it's beyond my imagination before that we could have strong engines in our pockets(thanks to Android platform) that can whip super GMs.A Carlsen-SF match would be interesting.
Carlsen has no chance.Stockfish can even give him a head start. This will be a one-goal game.
Kasparov is best in the world
His anti computer tactics is awesome
Fischer only play e4 but Kasparov is encloypedia of chess
Carlsen is like baby tell him to play like Mikhail tal or sacrifice some piece
he wont stand a chance
only high elo rating doesnt mean he is best
For me the best players are Alekhine, Tal, Kasparov! In nowadays all the players use engines to find better lines, without having understanding the meaning of the moves, just watching the evaluation of the engine. :) P.S. without any offense, but (for me) Carlsen is the most "boring" player.
GK thinks that if lost games don't count, MC can have a chance to beat SF once in a ten games match. The stress of losing a game puts deep psycological pressure on human player and pushes him to lose precision on winning positions. I agree with him. The computer becomes more and more unbearable when the human catches a superior position.
GK is my all-time favorite and a superstar attracting millions of chess fans. But i would be cautious to say he's the anti-computer tactician. He failed vs DB and changed his style against Junior and Deep Fritz X3D to cope with their deep calculations. Many chess gurus tell the anti-computer play doesn't fit the agressive tactical style of GK because that relies on more computation than positional sense. Kramnik is the most succesful in these terms against computers. However he also failed in 2004. After all he's human too.
Carlsen on the board is boring most of the time but he did the best he can to promote chess worldwide, i give him that. What's boring to watch in his play is in fact is ehat makes him the strongest human player. He blunders rarely and he has a presictable stability, kind of a machine. When you look at his blitz outcome, you see that difference. He's close to 3000 in blitz!
As much I know, the time of tactics has gone nowadays, its time was from Paul Murphy,till Mikhail tal.
Nowadays people's are worried about losing their elo..
Waiting for Alexei New updated chess engine.........
Hey Gurcan can u tell me
game format of rapidroid games
can someone suggest me where to put opening book that i hav downloaded with chess engine ?????
I m using droidfish n chess tournament app
i m using downloaded opening book but it seems every engine has its own book
so i think it should be better to have only one book or should i keep every book concerning with that engine ???????????
plesae answer m confuse
My compilation new aggressive Stockfish-230118(arm7,arm64v8).
Set the default contempt value of Stockfish to 20 centipawns.
The contempt feature of Stockfish tries to prevent the engine from
simplifying the position too quickly when it feels that it is very
slightly behind, instead keeping the tension a little bit longer.
Various tests in November 2017 have proved that our current imple-
mentation works well against SF7 (which is about 130 Elo weaker than
current master) and than the Elo gain is an increasing function of
contempt, going (against SF7) from +0 Elo when contempt is set at
zero centipawns, to +30 Elo when contempt is 40 centipawns.
See pull request 1325 for details:
This november discussion left open the decision of which "default"
value for contempt we should use for Stockfish, taking into account
the various uses ofStockfish (opening preparation for humans, computer
online tournaments,analysis tool for web pages, human/computer play,
This pull request proposes to set the default contempt value of SF
to twenty centipawns, which turns out to be the highest value which
is not a regression against current master, as this seemed to be a
good compromise between risk and safety. A couple of SPRT[-3..1]
tests were done to bisect this value:
Contempt 10: http://tests.stockfishchess.org/test...bc5902977e2901 (PASSED)
Contempt 15: http://tests.stockfishchess.org/test...bc5902977e28fa (PASSED)
Contempt 20: http://tests.stockfishchess.org/test...bc5902977e28fc (PASSED)
Contempt 25: http://tests.stockfishchess.org/test...bc5902977e2904 (FAILED)
Surprisingly, a test at "very long time control" hinted that using
contempt 20 is not only be non-regressive against contempt 0, but
may actually exhibit some small Elo gain, giving a likehood of superio-
rity of 88.7% after 8500 games:
What's the name of the engine you're using that has an opening book?You can just install it in DroidFish book folder...
Yes as Paulzzz said copy and paste into Droidfish book folder.Also why do you use so many question marks ???????????.I counted 11 in your last post :-D
Hi Lazar,I also downloaded the CT800 engine in its official site and when I tested it in DroidFish and CfA(no book settings) it seems that it has it's own opening book within...
Ah yeah...you're right! Cool :-D i hope Alexei at some point can compile a working arm8 version of CT800 for us.Its a good weaker engine with some interesting settings to experiment with !
Yes and the tests results of 10000 games for this dev version looks amazing!! Looks good enough to release Stockfish 9 perhaps?:
can u give me link for cyclone xTreme ?
Demon chess is open source any compile ?
and any fire chess engine coming for android ?
why there are many abandon chess engine whose rating are still higher ?
Deepsaros ippolit are still under development or what ??
should we discontinue using it or just wait for next update
i want to know all about chess engine give me links n sites
Hi,Cichess and Aristides is best.
Actually Cichess is know how to win it plays outstanding while it came from sf.
I saw this site after a long,it is great to see many updated and new engines for android plateform.Many thanks to Gurcan Uckardes and keep going on with more and more engines for chess lover.
Pedone 1.7 http://www.talkchess.com/forum/viewtopic.php?t=66341
My compilation official version Vajolet2-2.5 TCEC-11 (arm7,arm64v8):
Its confusing.So Dec 28 release is just tcec 11 even though pc exe is 2.5? Anyway so this is now the proper 2.5.According to the author there is a big elo improvement!Lets hope this shows up in Android too.Thanks Alexei!
Welcome back :-) Stick around and share your thoughts.Keep the excitement going !
Yes CiChess is much stronger than SF bev builds. In fact it is stronger than any other SF clone. It has much more detailed understanding about zugzwang positions (tactical and positional both). I have some of the toughest zugzwang test postions which SF is just can't understand even after minutes of thinking but CiChess is very quick to pierce through the hole situations within seconds. But there r some postions also which even CiChess also can't solve.
I won't agree, recently in a tournament among SF and its four clones, on two rounds and 20 matches, using hawk chess app, no book and 1 second per move tournament, the first position got was sugar xpro latest version from Alexis. the second was cichess,, and the fifth was SF, and I have both screenshot and pgn of the tournament, if someone not believe, tell me how to share it with you......
From my tests CiChess is the best for game analysis and problem solving by far in mobile devices, it finds solutions much faster than stockfish and other derivatives of fish, some times in less than a minute when the other engines need 5 minutes or more.
Isn't CiChess = to CorChess plus C language? And Corchess is optimized for TL that are 30min and longer? Thanks
Alexei, please compile latest version, thq s much,,
Alexei, please compile Brainfish latest version, thq s much,,
Yes, Cichess is almost the same Corchess, only in C language and therefore faster.
On February 1, there will be a release of stockfish-9, then Brainfish-9 will appear, then I'll do it. Wait.
yess Alexei, i very glad
there are many open source chess engine but why stockfish is only developing by community ?
Thanks alexei and gurcan wow stockfish 9 love it. Im so excited about it alexei.. thanks you so much more blessings in life sir
Haha i knew it.Once they got the extra elo from contempt set to default 20 it was going to happen.Nice!
Hi,sir Alexie please compile Nemorino latest version,it will be new gift for android community.much thanks
Hi Gurcan.There my compilation Stockfish-9 (arm7,arm64v8):
Thank you very much Alexei!:D
glad to have it
(even website shows only 8)
i think this should beat stockfish contempt 20
its time for match between aggressive , stockfish clone n derivative
thanks once again Alexei
On the official website, stockfish-9 will soon appear, while they select the fastest compilations.
Hi, sir Alexie please compile jinx1.0 it is based on fridolin2.0 and almost +146 elo higher.thanks
His rating in Rapidroid will be 2700+ Elo. I do not see the reason to do it.
Woohoo st9 ! Good luck Alexei! Lets hope your complile is the fastest Android build.then it will be yours that is hosted on the official site..if its the fastest?...is that correct?
Thanks alexei yes yahooo! Sf9 oh yeahhh!
Alexei can u tell me which is best betn them arm7,arm64v8
both support in my device?
Arm8 is faster of course
Arm8 is faster of course
chess tournament app playing with these all sf ( clone derivative contempt ) few round robin games
Still Sugar xpro is no. 1
I enjoy playing different chess engine wondering who will win match ? watching their style of play is exciting
thats why i m eagerly waiting for new 1
Does Zevra chess is new or stockfish clone ?
once again pgo vs arm8 which is best
I've tested games SF 9 vs sf8 and damn sf9 destroyed sf8 (no opening book 4 cores 3ach both armv7 and 1+15
I found the reason to the problem i had with armfish and tablebases in Droidfish, if you start analysis with any other engine and the number of variations is not 1 and then you select armfish for analysis, it can't use the tablebases, if you reset the value back to 1 then armfish works fine with tablebases and you can increase the number of variations as much as you want.
There is a bug but I don't know if it's Droidfish or armfish.
Well arm8 should be best for your device.its faster and therefore stronger :-)
I think zevra is a weak engine that Alexei ported a few months ago.its aboit 2000 elo i think.not sure.
Yeah same here.It seems like a fast compile too from Alexei!
Hi Gurcan.There my compilation Cfish-9:
Hi kevin, can you please share the link of sf9, if its for android...
u make this blog awesome
Anyone please compile this for android
it will be best to have
It's written in Pascal. I do not know anyone who could port it to an android.
Can u suggest me best tactical ,
beat positional chess engine ??
which games are awesome to watch in between
Alexei u r the only 1 which brings chess engines for android
hats off to u
today i spent reading all post from this blogspot
lots of contribution from lots of people
thanks for their dedication n their way of sharing information
My compilation was made the official port of Stockfish-9 on android. I can celebrate. I'm glad.
Wonderful Alexei. Congrats.
Hey Alexei Stockfish 9 is now out in official site.and it seems they are your builds.Nice!
What about the last version of ThinksFish for Android?
Cfish 9 for android Awesome Alexei, that was a fast compile!
Thank you for your effort
Sir Alexei, there's a latest update on Brainfish now, can you please compile it if you have spare time. Thanks in advance :)
This clone is stockfish.
Brainfish-9 has not been released yet. Use Cfish, it also uses the Cerebellum book. Brainfish is Stockfish, only with support for the book. The style of the game and all the algorithms in Stockfish, Brainfish and Cfish are the same. It's the same engine.
My compilation Brainfish-010218:
Brain is a bit stronger than cfish..
Alexei! Once upon a time when I was a Windows user, I remember there was a very very strong portable and lightweight software, called yeachess, I couldn't beat its first level, and it had 15 level hardest to play, can you tell me which engine was preinstalled in it?
No,Cfish stronger than Brainfish.
I played with arena chess
my fav is Spike 1.4
still no update for it
Currently playing with Embla chess
its perfect for my elo in Android ( Droidfish )
thanks for this
Using analyse this app, two matches between st8 and st9, I found no difference, both are drawn... anybody agree With me?
What is your online playing elo?
Karim , games goes up n down thats why need hundred or thousand of games required to calculate which is best
i m club player but i dont play much as i love watching engine tournament which shows variety of strong moves
I ran a small test stockfish-9 vs stockfish-8 .330 games, 3 cores, control 30s + 1s.
Stockfish 9 showed +76 (+ -20) elo. You just need a lot of games for the error to be less than the difference in the Elo.
Hi Gurcan,do you have the latest TCEC opening book?Thank you very much.
Alexei can u please compile any new chess engine or updating some chess engine
You makes android community chess happy
Alexei please compile
Firebird which beats shameless Rybka
Chysiddh! What do think how much time would it take to compile an engine to android? everyone request his favorite engine for compilation...
Alexei ! I don't know, why you never agree with me, I told you the brainfish is stronger than cfish, you replied no, now check it yourself, brainfish elo is 3379, while cfish is 3348...
no Karim, really Cfish is stronger than brainfish
But how? Explain your experience.
Brainfish is Stockfish, only with support for the book, and so it is no different. Cfish is Stockfish in C language, so it's faster by 20% and therefore stronger. You do not look at the ratings on the PC, the android is a bit different. On Linux android the same Linux) there is no stronger Cfish, even asmfish loses to him. Give the match at least 200 batches of Cfish vs Brainfish and see.
Cfish also supports the Cerebellum book by the way. I do not agree because I checked it with hundreds of parties. And if you connect a book to Brainfish and make a match against Stockfish, but put their debut book 8 move.pgn (it is used for stockfish testing) then Brainfish will not advantages, even the book does not help. This is all checked by thousands of parties.
You can not draw your conclusions on the basis of 10-20 games, they will not say anything about the power of the game.
Well,its not based on my conclusion I search on Google I found brainfish won some of championships, there you can see the cfish on list,I won't mention the blog until you allow me to do so, and according to my experiment I found it stronger, that's all I know
In my opinion SF is still not that good in understanding complex zugzwang positions. This is my experience tells me and I have many zugzwang test postions (which r in fact reveals true positional and tactical beauties that no other chess positions even dare to offer). SF will be truley versatile if it ever will manage to solve those tricky postions or develop understanding how to play those positions correctly in short times. Hope in future it will be able to cross those ultimate hurdles.
Yes brainfish is literally byte for byte the same as Stockfish ECXEPT in that it allows Cerebellum book as a book.In fact some users use Brainfish without Cerebellum book on PC instead of Stockfiah because they find the compiles faster than the Stockfish compiles. Cfish is basically at LEAST 20% faster than Brainfish whilst beung the same program.So its hard to see how Brainfish/Stockfish can be stronger than Cfish.If Stockfish/Brainfish was stronger than Cfish then it means the Cfish project has failed and shouldnt be continued imo.Either way Happy gaming karim :-)
Now I'm surrendered to your experience lol. I won't argue again about this topic.
you are right, I faced with the same issue.
Friends, I apologize. There was a problem with arm7 versions of Cfish and Stockfish. They play below their strength, it's caused by pgo optimization. I used the command bench 16 1 15 and the -fno-peel-loops flag when creating. It turned out that it improves speed but worsens other algorithms. I revised the creation of versions of PGO and I think that everything is OK now. I note that the arm64v8 versions work fine, the problem is only with arm7.Low you can download the improved versions of Cfish-9 and Stockfish-9. Also I think that with a simple analysis , arm7 version worked well. The problem arose with the game.
Thanks, and God bless you.
Thanks once again Alexei for ur hard work
But I'm not sure even in these versions, tests are needed. I may have to give up PGO. I do not know what is involved, but arm7 looks weak.
Downloading your revised one, immediately I deleted cfish ach version
Sir Alexie,Please compile this new one written in java.
Sir Alexie a new chess engine is available "butter1.0" in C++,take a look.
i hav 2 android, 1 using brainfish and other using cfish, every 100 game testing, Cfish always win, about 10% from 100 test playing
Yes butter.Good find Rahul! Im also still hoping "Opental" will be ported by Alexei.Opental is basically a special tuned standalone version of Rodent chess engine.Its tuned to play like Mikhail Tal!!...and it really does a great job at it.PC version produces some beautiful games!
C++ chess engine derived from Gull 3
please compile it for android
it is strong comes in top 10 in Jurek rating
Lazar, opental engine play great in PC version.
Had you ever see "Rashid Nezmetdinov" game. He has great attacking style,though he is not GM, yet he was IM.I love his playing style.
YOU MUST WATCH chessgames.com
Thank you for optimizing Stockfish_9 pgo. I wanted to ask - when you released Cfish 9 alonngside Stockfish 9 on: February 4, 2018 at 1:16 PM, did Cfish_9 suffer the same pgo optimization problem as Stockfish_9?
Does this problem exists at stockfish.org since you say that they use your compiltation.
I assume the arm7 binary at stockfish.org has veen updated by Alexei as well ;-)
Yes he has left us some exciting attacking games!
I think st9 with Cfish9 in one 7z file format is the strongest..
Droidfish just got updated to version 1.72 featurung Stockfish 9 ! This is Peter Osterlund's own compile of Stockfish and there are bunaries for arm8 arm7 (pie & nopie)
mips and x86.Nice!
previously u said Pedone doesnot work for ur device
download from it ,it has android version too
Still he doesnot put his own strong texel chess engine into droidfish
in playstore many review about chess engine tournament selectibf different engine
but no improvement in it
Why put texel in Droidfish? There are 2 seperate apps for texel in Open Exchange format
programmers trying different way to improve chess engines and apps for chess improvement, I found none of them to create an app for openings training, or an app to create your own opening book...
Here are the final versions of stockfish and cfish (9). After a long search, all problems are deleted. I checked stockfish-9 and it just tears stockfish-8 AP. Because of some patches, it became difficult to apply the LTO + PGO combination and I refused them.
Thanks Peter Osterlund.
My compilation stockfish-060218 + Cfish-060218.
Thanks Alexei! Any chance you would compile tbe latest rodent or even Opental chess engines? They play interesting chess!
Nakshatra is a variant chess engine originally built to play suicide chess on FICS.
please compile it Alexei if possible
Android version of Wyldchess present here in chessdroid n its website is same or not?
Gurcan , Lazar , Alexei
So sorry if i says mistakly say something wrong
i hav read post about hayabusa before
now i found out in
i hope u guys found it before me
Hayabusa is also available in the app store.I prefer the Magnus engine though whose author is part of the Stockfish team,Mr.Tord.
Hi, did anyone test senpai2.0.
its amazing,In next Rapidroid everyone will see its power. Plz see screenshot
Hi,see another screenshot.I think Pedone1.7 & Laser1.6 not strong in android but in tcec they play much stronger the android.
Match between fire&senpai
Hi everyone, see unbelievable result here. GAME PLAYED BETWEEN" BLACKMAMBA2.0 & SENPAI2.0"
Hi Chysiddh14,I know you always want new engine and me too,
You should try senpai2.0,it has great attacking style.
In next Rapidroid,surely,senpai2.0 will take place of blackmamba.
Chysiddh you must try senpai i. Your chess tournament.
Unfortunatly, sir Alexie didn't compile sctr(defenchess)latest version and now sctr chess link has been dead.,if he did that then we get another new and strong engine for android.(•_•)
Nice to hear from u rahul
but senpai 2 is not working in my device only senpai 1 works
it seems u have another version of Senpai 2.0 AP
please share this with me
n u r right i love new engine
only stockfish , with its clone , derivative game will be boring
every engine has own style which i loved it
please check vajolet
u r latest compilation it plays vry low
even defeated by zevra n zurichess
i guess only few round within them is the problem but also check once please
Hi Chysiddh,try this, it will work. It knps is low but result great.
Hi chysiddh, tell me above link is working or not(senpai).
Yeah , it works thanks Rahul
Stockfish is derived from Glaurung
Sugar, a UCI chess playing engine derived from Stockfish
Sugar xpro is much powerful than stockfish
then we should opt for sugar development not stockfish
what ur views everyone??????
few round robin between all chess engines
opening perfect2017 , 2 moves ,chess tournament default setting
My opinion,it might be not true
Sctr has ability to win many games but it rename as defenschess , its not appropriate
Demolito is much stronger than Pedone n laser
Komodo 9.42 beats stockfish 7 in few games
while Protector,Texel,Andscacs,Firenzina,Robbolito draw with stockfish 7
Zurichess speed increases as game progress n eventually win unbelievable with many chess engines
Ginkgo is perfect competitor for Andscacs while Fritz is weaker
Critter plays complex games,
Andscacs for pushing pawn strom n looking Knight alwz in C7 square n Komodo,Cheng for human playing style
Firenzina,Ivanhoe,Deepsaros stronger playing Like Gull 3
Critter should be developed by merging with others like ( Rykbba into Fritz )
Not only stockfish but also others open source should be developed by community to have tight competition between them
if u have working Nemorino , Scorpio n Crafty ,also bobcat 8 ( only bobcat6 works mine)
kindly please share this with me
u n i have same 64 bit naugat thats why it should work in my device
Hi,see result after 300 games between senpai2 vs senpai1.
Chysiddh, I have same problem as you bobcat8, crafty and also protector are not working in naugat.
One year ago, i had a kitkat android version mobile and all chess engine working superb in kitkat.
"Naugat" is too bad for chess engine.I HATE IT.
try downloading all chess enginr with all version from this chessdroid
( view web version , - all Android chess engine )
i have just given u name if u want i will share with link later
Chysiddh,Share link please of working protector.
Hi, sir Alexie please compile latest scorpio.It has been much improved.
After getting critter Firenzina Rotor works by ( Gran virt hex editor trick )
there is no way to hate it
even komodo 8 website works with this trick
Alexei all arm7 arm64 n pgo works best
even jim ablett compile some works arm5
only Aprijal compile dont work even arm7 arm64
rahul add me firstname.lastname@example.org or fb.com/Siddhartha.chy
please tell me it works or not
Hi chysiddh im curious .Do the arm64 rodent engines (rodent risky arm8 and rodent III arm8 engines work on your device?See all android chess engine link to download them.They are interesting engines as you can add pereonality files and slow the engines down etc.just want to know if they work on Nougat ? By the way AP Robbolito and Ivanhoe9.45 arm64 both work for you in Nougat?
Hi all, I found that alphazero beated stockfish 8, I liked its style of play, really tactical as a real GM, if someone is wanna know more about it, plz Google it, alphazero vs stockfish, you will get 10 matches pgn file.....thanks
it is from chessdroid which works in my 64 bit naugat
Hi Chysiddh, thanks for Ivanhoe and Robbolito working nice.
but Protector is not working.
Ok good do.they both work.what about rodent? All these engines work on my mobile but im not on Nougat.Thats why i asked about Nougat. :-)
Chysidh! Do you yourself compile android chess engine ? Or sharing others builds?
Crafty doesn't work both in my marshmallow and old jelly bean devices.I have no problem with rodent and it's one of my favorite engines.Hawkeye terminates during middlegame in DroidFish and CEPA.
Rahul,your link doesn't work(senpai)
Let's make a request to Alexei to compile the latest GreKo,CycloneXtreme,Nemorino and Scorpio...
please sir Alexie compile the latest chess engine Greko,Cyclone,nemorino and scorpio......please please please
Rahul...some friendly advice..NEVER beg...unless you are truly desperate.Begging makes a person look very weak.Just saying..
i have mentioned earlier , i have downloaded from this blogspot
every engine has many version ,only few works according to cpu architecture , firmware , android version
Rahul,try downloading every version and everything from this chessdroid then try on droidfish
then only u know which works
( if arm5 try hex editor tricks)
view web version - all android chess engine
These 3 version works in my 64bit naugat
Rodent_III.0.171 doesnt works which is latest
This is from this blog chessdroid
i tried aprijal also but not successful in any engine
Chysidh ! How can you prepare an opening book with only one opening ?
Nemorino I can not do, there embedded the code into assembler and my engine does not compile. Yes, and now I'm busy with the other.
Alexei thanks for this effort but in free time try compiling as there is lot of progress in chess engine.
N we all are waiting
In Opening book choose random move of all
i prefer book depth as minimum 2 as some openings advantage white or some engine
Its better to let engine choose which is best
if u prefer playing with human try to get him out of book by not playing series of line.
I think its not about preparing but about thinking n finding move which is best of the best
in engine tournament i try to find out,how they continue when human struggle to find strong move
How can I practice an opening with droidfish app ? Can someone understand my English, is it that bad?
Karim,im not sure you can practice a specific opening with Droidfish.
Lazarus! This is why I'm asking how to create your own opening book, just to contain simply one opening.
