    The strength reduction is mostly based on a combination of two techniques:-protocol compliant version of Strength parameter.

    Limiting the number of positions searched - this reduces mostly the tactical strength of the engine;
    Purposely picking a move the engine knows is not optimal - this reduces mostly the positional strength of the engine.

    The combination of the two produces a game with both tactical and strategic (positional) flaws.


    The following table shows the estimated Elo of Houdini at reduced Strength levels. It is based on the feed-back of several users:


    Strength  0 => 1200 Elo
    Strength 10 => 1500 Elo
    Strength 20 => 1800 Elo
    Strength 30 => 2000 Elo
    Strength 50 => 2300 Elo


    What is the highest strength level that you can consistently beat?


    UCI-protocol compliant version of Strength parameter.

    Default 3000, min 1200, max 3000.


    Internally the UCI_Elo value will be converted to a Strength value according to the table given above.

    The UCI_Elo feature is controlled by the chess GUI, and usually doesn't appear in the configuration window.


    UCI_LimitStrength (checkbox)

    Activate the strength limit specified in the UCI_Elo parameter.

    This feature is controlled by the chess GUI, and usually doesn't appear in the configuration window
