    Considering that White has voluntarily immolated his rook...who really cares?

  • #6

    59. .... b6 looks obvious. Black will effectively playing two Rooks versus one (one White Rook being trapped on g5).

     

    p.s. 59. ... b5 ia also a possibility. Some calculation is required, after all.

  • #7

    Well, it's either that or ... b5 (lol)

    Where can you buy a slominski jerry engine? The houdini is easy to find, but this one...

  • #9

    Still, might be worth the effort (at least the Slominski keeps its rooks free).

  • #10

    astounding!

  • #15

    I don't believe for a second that a 2200 computer could entomb a rook like that.  Hell, even a 1200 would have a hard time coming up with that genius plan.

    11. g3? Are you sure Houdini did that?

    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
