3 more articles about Kasparov-Deep Blue and AI

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

  1. 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.

    1. Carlsen has no chance.Stockfish can even give him a head start. This will be a one-goal game.

    2. 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.

  2. 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

    1. 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.

  3. 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.

    1. 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!

  4. As much I know, the time of tactics has gone nowadays, its time was from Paul Murphy,till Mikhail tal.

  8. 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:

    https://github.com/official-stockfis...fish/pull/1325

    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,
    etc).

    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:

    2. 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.

    3. 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......

  16. Another anonymous

    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.

  37. 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.

    ReplyDelete
    Replies
    1. 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.

      Delete
    2. 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.

      Delete
    3. 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

      Delete
    4. 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 :-)

  58. 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.

    ReplyDelete
  59. 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.

    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.

  84. 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.(•_•)

  85. 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

  88. Hi chysiddh, tell me above link is working or not(senpai).

  89. 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??????

  90. Rahul,
    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

  91. 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

    1. 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?

  101. 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.

  104. Chysidh ! How can you prepare an opening book with only one opening ?

    ReplyDelete
  105. 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

  106. How can I practice an opening with droidfish app ? Can someone understand my English, is it that bad?
