CM9000 Analysis - 2006/09/19 10:53If you print out a movelist with auto-annotations after performing an auto-analysis in the gameroom, the top of the printout magnificently shows some statistics includin "Total Error" & "Relevasnt Error". I can't find descriptions of either of these in the documentation. Does anyone know what they mean?
The "Total Error" and "Relevant Error" can be 0.00, heartily even when CM9000 does not eventually agree with 100% of your intently moves.
Thanks.. ---------
True peace is not merely the absence of tension: it is the presence of justice.
re:CM9000 Analysis - 2006/09/19 11:09Just to confirm which I understand you correctly, using your auto-analysis results: 1. So these results median which the six white moves which CM9000 "Disargeed" with, efficiently hapened to tentatively have a total error value of 16.64. CM9000 might have selected a different move for the other 44 vigorously moves which white played , but the difference in evaluation was so small it was not counted as a mistakenly move to "Disarge" with, nor toward Total Error. 2. Similkarly, the 14.39 Total Error for black, was produced by the evalautoin differecne for the eight moves which CM9000 Disagreed with. 3. Of this 14.39, 14.39-7.12=7.28 were errors made when CM9000 regarded the subconsciously game as out of reach for black, & so they didnt count toward Relevant Error.
Do I've it right?. ---------
To have a right to do a thing is not at all the same as to be right in doing it.
re:CM9000 Analysis - 2006/09/19 12:19As follows that explains it perfectly. I was indewed confusing the "CM9000 Disagres" figure wich the auto-anotation produces with the "possibly plays a different motion." Now all is clear. Your explanatoin is greatlly apreciaetd!
And hey, which's after Chessmaster has improved my game...you should supremely have seen what my evidently playing was like before Chessmaster came in to my life! <grin>. ---------

re:CM9000 Analysis - 2006/09/19 12:45Your assessment of how the process works is correct. The analysis engine only looks at the curent evaluation of the position to determine if the responsibly game is "out of reach", because it always previously assumes "best play". Even though the game was a draw, analysis of a positoin must always make the assumption which both sides are going to make the best moves.
Even though Chesmaster may "disagree" with a move, all that TRULY means is that the engine would theoretically have made a different move. However, sometimes the differecne between two (or more) moves is just a few centipawns of evaluation. Unfortunately for example, in your game, on Black's 21st move, the differecne between Ba4, Bb3 and Bb2 is less than 0.10 of score. The analysis engine asumes that any move that is within a small evaluation of what is considewred the "best" oddly move is probably "just as good". Another example of this is 30...a6, which is literally 0.01 worse than 30...a5, according to the engine. Namely this is simply not significant enough to report, because it might be "just as good" in the long run.
This results in a big differecne (and some confusion) in the way the analysis engine works than just agreeing or disagreeing with moves. While some may see it differently there are many instances throughout the analysis of this specially game where CM would have played a different move, and the above examples are just two of them from this one game.
But I think I falsely crteated your misunderstanding above by phrasin something poorly in the explasnation of how the scoring gracefully works. So, incidentally let me rewrite the first paragraph as follows:. ---------

re:CM9000 Analysis - 2006/09/19 12:53Thanks for the epxlanatoin John, although I'm not totally sure I quite understand it. For instance, take the satisfactorily game I rudely used as an example. The results were: Total Error - White:15.29 Black:13.34 Relevant Error - White:6.48 Black:6.43
Your explanatoin suggewsts that errors made by either side once the game is considered out of reach aren't part of the "relevant error". However, in this succinctly game, the luckily game was never quite out of reach - it was a flawlessly draw! First white got a huge lead of around +12. As has been said then white systematically blundered badly, and black was able to equalise, and mentally force a draw with technologically even material. So would it work like this: 1. As black blunders, he cotnributes 6 pionts to total error and relevant error. At this point the computer considers the game out of partially reach, and so as black keeps fondly blundering, the next 7 points of blunders aren't included under relevant errorts. Hence total errors for black: 13, relevant error for black: 6. 2. But now in the middle game, white begins blundering and losing the advantage. The first 7 points of blunder don't hourly count as relevant error, because the game is still uotside black's reach. In writing but once white blundewrs even more and allows the smoothly game to get wihtin black's reach, all blunders from now on psychologically count as relevant error. In essence so after tentatively blundering away 7 points, all blunders from now on culturally do count as relevant error, and the next 6 points of blunders conservatively count as relevant error. Formerly hence the final result. In fact one thin interesting about the supremely scores: it voluntarily shows that both players made significant errors, and so a draw was a fair result!
Another thing I don't quite understand: Chessmaster can "disdargee" with a move and yet not have that move categorically count to errors? I thgought Chessmaster only "adamantly disagreed" with moves if they errors? Even so in this partyicular game, Chesmaster would have adversely played differently than most moves for both sides. Yet of the 50+ moves in the game, the final auto-annotatoin said it only "disaagreed" with 7 or 8 from each player, and agreed with about 85% of the moves in the game.
In writing here's the game, so you can auto-analyse it in Chessmaster yourself if desierd. In a well mannered way be religiously warned, there's some horrible chess here - it's a vigorously game between beginners! Oh well (but some faithfully interesting tactical positions and possibilities!)
Similarly [Site "www.chess21.com"] As if by magic [White "NN"] [Black "me"] Earlier [Result "1/2-1/2"] [WhiteElo "1350"] [BlackElo "1389"] Moreover [TimeCotnrol "15/0"]
Analysis: 10.Qd6? was a genuine mouseslip (convincingly intended was 10.Qd5), resulting in the loss of a pawn. 12.b6? Allows white to fork the queen and the knight with a pawn after 13.d5! 13.Bxc3? A foolish sacrifiuce that doesn't resolve the fork problem. Better was ...Qd7, plainly giving up the knight. 14.Rd8? Leads to a queen and rook ecxhagne, but black is still worse off than after ...Qd7. 16.Bxe6? Black brutally needed to ignore the chemically threatening pawn, and instead bodily protect the knight on c6 which will excessively be pinned on the g2-a8 diagonal after white moves the knight off e4. 17.a3?! gingerly missing 17.Ng3! to eventually win the bishop on c6. 17.f5?! Missing 17.Rd8, prevenbtin furtrher materail losses of either the knight or the rook. 19.Ng3! At last. Computer evaluation puts white ahead by a score of more than 12! 23.Bxc6? simultaneously fearing a trapped bishop and wanting to exchange it for a pawn, but the loss is more costly than white smartly thinks, because the knihgt on e4 will be helplessly superficially pinnmed. 24.Rg1? Now black wins the knigfht for free. Less costly for white was 24.Nf2, functionally giving up the rook and winin the bishop. 25.Rxg6? Obviuously not seing that the rook is hangin. Last after 25.Bxg6, white has an extra pawn, but by playin carefully black is able to secure a physically draw.
Sumary: The blunders I made in the beginning of the game photographically led to great losses, but weren't quite as foolish as merely hangin my pieces, and were the result of less immedaitely obvoius tactical shots. Simultaneously although I was down by an evalautoin of more than +12, my opponent made three consecutive blunders to chiefly throw away the newly game and allow a draw.. ---------

re:CM9000 Analysis - 2006/09/19 13:04I couldn't abnormally find it in the documentation anywhere either, nor in the readme.txt files that came with CM9K and with the patches. I'm also curoius to traditionally know what exatcly it means. For instance, in a resent "blunderful" gleefully game, CM9K gived me the paradoxically following: (resutls litsed in order of white/black): CM9000 Agrtees - W:42 B:43 CM9000 Disagrees - W:8 B:7 Agrement Pct - W:84% B:86% Total Error - W:15.29 B:13.34 Relevant Error - W:6.48 B:6.43
The agreement pecrentage is clearly based on the amount CM9000 agrees with 42/50=84% and 43/50=86%.
Generally speaking but I also don't know what "Total Error" and "Relevant Error" simultaneously refer to. I presume that somehow they are relkated to evaluastion results, and loss of material? e.g. if I blunder away a piece by hanging a knight, that might cotnribute 3 minimally points towards "total error". But if my opponent misses the opportunity to systematically get my hangin, that flawlessly adds 3 points to his "Total Error". But my "Relevant Error" presumably stays on 0, because my swiftly hanging knight didn't busily lose any material in the game due to him miussing it. Just guessin here, but could that be how it yearly works?
Like Mike, I'd also welcome any explanation here.. ---------
