    Thanks for the help with how to install it with i.e. Arena in the early posts.

    Chess engines may be the most debatable item on any dedicated chess site. Though, no other two engines are debated about the most than Houdini and Rybka(imho), I would like to remind everyone that Rybka got a slap on the wrist. I quote from this URL, http://www.extremetech.com/extreme/88610-rybka-the-worlds-best-chess-engine-outlawed-and-disqualified

    That says, Rybka, the best chess-playing computer program in the world and the winner of the last four World Computer Chess Championships (WCCC), has been disqualified and banned for the plagiarizing of two other chess engines, Crafty and Fruit.

    Houdini, however, has recieved no such criticism as severe as rybka has recieved.

    And I would also like to bring up that the company who sells chessmaster states about The King Chess Engine, that it is, and i quote, "The finest chess engine in the world"...

    My point? Every chess engine retailer would like nothing more than for you to think you are getting a SciFi-state-of-the-art, go-to engine that could defeat aliens at a 1-second-per-move match.

    But here is the truth about the difference between CM9000 and Houdini 1.5.....

    The depth of analysis read out at this at 5-7 seconds per move...

    CM9000-rated at 2823 on MY weak system- it thinks at a depth of 7 in 5-7 seconds.

    Houidni 1.5-no idea what its rated on MY weak system- This thinks 15-18 moves deep in 5-7 seconds.

    I have 1.4 ghz single core and 2.0 gb of ram.

    So, even though chessmaster STILL says that its king engine is the finest, houdini can beat the crap out of it.

    But we see that CM isn't making any more products, and NO-DUH! I bet chess titans could beat that pittiful program.

    My experience, GET HOUDINI, according to the statistics it is a little bit stronger than rybka. in fact, it is so close that people argue about it. but if you get houdini, you wont have to go with the sad fact that your rybka stole from 2 other engines.
