I have just discovered something very interesting that I never realized! De la Maza had mentioned it, but I didn't really pay attention to what he had said in his article. Anyway, if you input one of your games into Chessmaster 9000 or Fritz (perhaps) and have the programs analyze the games, you can get a data sheet that shows you an: agreement percentage, Total Error and Relative Error. Well, I analyzed one of Morphy's games and there was: Relative Error: 0, Total Error: 0, and Agreement percentage (100😵. And so, I was thinking, what if I input a Master of 2400 who played a 2050 player, and the 2050 player won. So I did. The 2050 player (eventhough he won) had the following after analysis: 91% agreement percentage, 0 relative error, and a little bit of total error. So, I was like, hmmmm... Oddly enough, the 2400 player he was playing had 100% agreement precentage eventhough he lost. Goes to show you can't win every game even if you make great moves. Anyway, to get on with the story, I figured, if there is a 9% agreement difference between the 2400 Master and the 2050 Expert, then wouldn't it be obvious that there is a 2.5% percentage different for each 100 points in rating over 400 points span? Yes, indeed. So, I took one of my own games I played against my 1700 chess computer and figured if this 2.5% different each 100 points was true, I would find out my true strength when I'm playing seriously. After my game was analyzed, the agreement percentage was 85% versus the 83% the e-chess computer earned. I am now in the process of understanding what De la Maza meant. So, I am making a chart and I am now trying to insert other rated games of different levels to see if my theory works. Needless to say, I was wondering if you guys think this is the equivalent of a performance rating? If it is, stupid me. But, I figured this out yesterday, and I was astonished. 🙂 Anyway, if you don't understand what I mean, look below:
2400 (IM) - 100% Agreement with Chessmaster 9000
2050 - 91% Agreement Rating with Chessmaster 9000
1700+ - 85% Agreement Rating with CHessmaster 9000.
Going to try other ratings below 1700 at specific increments to see if these ratings are applicable within a 2.5% Agreement rating percentage. 🙂
I've had > 90% agreement on some of my 1400-level games in Chessmaster.
So, your "theory" hasn't much meaning. If I didn't make mistakes I'd be a GM, but the reality is that I do even whether I'm fully focusing or not.
Your problem is that you take ONE game and consider that as a foundation for your "theories." You beat a computer and say you're at 1700, or you pick one Morphy game and say 100% agreement means you play at GM level. The reality is that the sample size has to be substantially larger than one game. I can almost guarantee that each RHPer has at least one or more games with a >= 90% agreement in CM or Fritz, but the question is whether or not they consistently perform at that level. If that 2050 expert in your sample consistently played at that level then he wouldn't just be a 2050 expert any longer...
Originally posted by Sicilian SmaugNo, I'm not saying that means I'm 1700. That's only my opinion. But, as Chesswick said, everyone on here might have a 90% agreement rating on one of their games. That's true. I'm not disputing that! But, if the computer consistently plays at a 83% agreement level and I beat it every time - which I do - then I'm not only judging one game. I'm judging lots of them! If you consistently hold 1700+ performances in standard OTB play, then you obviously are a 1700+ player. That is my mission to prove. I will research all of this. I will insert 20 of my games, and get the agreement percentages on all of them. I will post the data later. My research isn't over. Although I did look at all of Morphy's games and he has consistently a 100% agreement percentage. 🙂 So does Fischer.
hmmm, so you have proved to be 1700 strength? Doesnt your RHP rating say otherwise? About time for you to prove this 1700 ability on this site or forget about it and these tiresome threads.
Anyway..im heading for 1700 on RHP maybe in the next few days, the holy grail. woohoo 🙂
Originally posted by Sicilian SmaugHey, those are good game! 🙂 You want me to enter them into my Chessmaster 9000 and see what your performance rating was? LOL Wouldn't it be ironic if it was 85% and the equivalent of your RHP rating? 🙂)))
ok, fair enough, anyway check these clan games ive just completed against Via, one won, one lost. One of the most enjoyable and competitive challenges ive had in a long time..
Game 1654443
Game 1654441
Originally posted by Sicilian SmaugI just know it has to be above 85-88 agreement percentage in both games. I'm going to run it through. I already e-mailed to my yahoo e-mail. 🙂 I'll let you know when I've inputted it all. Oh, incidentally, check this game out I'm playing. It's almost over. I took more time and really thought on this one: Game 1683218
Sure go for it.. i dont have access to any programs, Any thing i missed would be helpful. I know i could have won a pawn in the game i lost (move 23 Nxe5)but i had other ideas. Wrong ones. 🙁
p.s. Game isn't over. So, no comments until it is. 🙂
Not sure what all those numbers mean.
If you studied a lot, played alot, got lessons, a coach, etc. You will get better.
Sometimes strong players, make weak moves against weak players.
It could be they dont get pumped as much as playing someone stronger.
This is why sometimes you score wins against higher rated players.
True strengh and ratings are each players own to know, and expand on.
The best thing you should know, is your true capibilites, and weakneses.
This way you can work on them.
Too much technical stuff, takes away from the object of the game...have fun!😀
Originally posted by Sicilian SmaugHey, guess what! Grandmouse-ter is going to give me my points back and more after I lost that 1 out of 2 games to him. Down with the mouse! Game 1683218
Nice1, cheers 🙂, will it say about anything i missed, any missed tactics etc? I dont know how these things work 😕
Down with the mouse! Down with the mouse! Down with the mouse! time to squeak! I'm just picking at him. Don't mean any harm. Just happy with the win.

I ran a morphy vs another gm into CM10000 when i first got it and the agreement for morphy wasn't 100% more like 90% some. When your playing weaker opponents its easy to find good move because they can't play at you level.
Anyways, your can't use the chessmaster % agreement like that. 2-3 years ago when i was, i'm guessing 1400 OTB I used to get agreement percentage 85% average on my wins, and 77% on my lose on CM8000. Recently I was playing CM10000 tournaments on a 2.4GHZ computer and just analysed my loses vs the personalities I was playing against in the tournament. I had a 82+% on my loses! These games were blitz games with 10 minutes each side. Imagine if I had put in my rhp games or OTB games. Ponder over that will ya.
