    What do my Fritz results mean?

    I still use Fritz 8. Although I have had it for a year I noticed some "test sets" today. I found that you could run this "tactics test" for your program. It is a series of tactical positions where the progeram must find the best continuation in a time limit. For instance one position was dfrom the game Botvinnik vs Capablanca Avro [1938?] where Botvinnik is about to uncork that famous combo with Ba3! .

    The results: 195/210 success rate [92%] at average solvre time of 10.92 secs/53 secs . Time limit set at 600 secs. A brand new computer used with a very powerful chip.

    What do the results mean? How do they compare to other programs/engines/computers etc? Is there anywhere on the net where I can get a comparative schema? Or is it another example of Fritz assuming that I have 9 degrees in computer science?

    I think you may have a typo there and you meant 10.92 secs/9.53 secs.
    When you say a powerful chip what chip at what speed exactly.
    Also how much memory was allocated to the Fritz8 engines hashtable.
    Lastly do you have tablebases installed and if so are they the full 3,4,5 pieces tablebases and do you have any 6 piece tablebases installed.
    All of those issues will impact on your results.

    This is where it gets tricky.
    Firstly you will notice you failed on 15 of the tests.
    You need to remember that the test suite you ran (Marathon) is made up of 209 positions from the Encyclopedia of Chess Middlegames and 1 Shirov position. Therefore you need to determine did Fritz 8 really fail or did it actually find a better continuation.

    ok

    I am a computer ifnoramus. I went to control panels and system so the chip is:

    intel[R][TM] 2 CPU
    6400 @ 2.13 ghz
    2.14 GHZ, 1 gb RAM

    As for the hash tables and stuff, that is double dutch to me.

    What is a hashy table? What does it do?

    I only have whatever tablebases Fritz 8 came with. I have not installed any others. From what I was watching [ the"correct" answer is given as each test is attempted] I tried to go through the correct answer myself in my head. I was watching one of the instances where the computer "failed" and the correct answer was indeed better than the Fritz 8's alternative.

    Core 2 Duo. Very nice. I'd chuck another gig of RAM in there personally.
    So what's your excuse? To run like the devil's chasing you.

    See you in another life, brotha.

    yes

    It is a nice computer. Real fast. Got it all made by a technician rather than buying it at a shop.

    The dual core is a nice asset; as the tech said to me, it enables more than one thing at once to cruch into the memory etc.

    The supposed correct answer.
    I suspect some may be wrong.

    Can you please list the numbers of the 15 tests that your Fritz8 failed to solve.

    The Black rook isnt on h2 but on h8. There is a white pawn on h2.

    Rxh2 is the supposed solution.

    The correct fen for 207 is

    that's good

    Clearly my Fritz 8 takes its diagrams from the soln rather than original posn.
