    does it matter what CPU performance u have?

    Houdini is strongest, no question. Does this mean it will be the best program to help improve your game?

    I ran games between Rybka and Houdini all the time. Houdini always wins. Some draws, but Rybka rarely wins a game out right.

    You really should look into TobyTal... unbelievably hard. I can't beat it at 1100 setting... it plays around 2500 no matter what.

    You guys are crazy? Rybka? Are you serious? Houdini will decimate Rybka with the blink of an eye! Rybka is the fake twin of Houdini.

    To Sheekrisna: I believed Arena has its own book. Good point. Well, I haven't read about an specific book utilized in engine vs engine matches. Probably this information has been posted, I don't know... I did my short test by just letting the engines play. I repeat, it is a good point, I mean the strengh in various openings. Some other ideas anyone?

    Herbanmusic, I check your info. Thanks and Greeting from this tiny Republic in Central America.

    In the several engine rating websites/forums theres dozens( hundreds actualy) engine books in several formats( bin for stockfish, , for fritz, for chess assistant, etc etc etc). For stockfish irs in .bin format. and one of the most stable is the perfect( dont know the number of latest version)...But f you use Lucas chess training program( has lots of top engones) you can chose the opening book i think in these newer version...Plus a great training program as well FREE !!

    I have an idea. Let's use Arena to settle this issue down. Arena allows the engines to play against each other. Later on publish the results of the test.

    One more thing is the the engines must have the same number of bits. For people who do not know what Arena is, let me tell you that it is a free GUI or program you can use to install all the wonderfull engines mention. The engines must be downloaded and install (some of them already come with Arena). I have done an informal test with Rybka, Houdini, Stockfish and Robbolito and it seems that Robbolito is better. All are 32 bits.

    First Stockfish won 6-0 against Rybka (6 games). Later, won 1 1/2- 1/2 against Houdini (2 games). Robbolito won against stockfish 1/2; 1/2; 1/2; 1-0. (4 games) Mi processor is Atom. Remenber this is a QUICK, INFORMAL TEST.

    Don't forget to publish the results for all of you who will do the test.

    You losers all say Houdini is better? Why? It has been proven by science that Rybka is superior. In fact, the developers stated categorically--categorically, comrade--that Rybka was better from the beginning.

    Svoj komentar sam dao,da li uvek trebam ponavljati,sad vise neznam i ne koristim ni jedan od pomenutih programa100 % .

  • 3 years ago


    Why are people still voting for Rybka? Houndini is the strongest, period.

  • 3 years ago


    True @lgbarn, Fritz will make you lose, unless you're playing D class players.

    I would suggest Toby Tal to anyone that lives in the Midwest. 3000 avg rating.

    which cost more? thats the strongest I would say. Pay for what you get.
