Chessmaster personalities

Response to # 65........no i left that at 9 points......if u make the opponents value 9 and YOUR value say.....7. Then from the engine's standpoint a trade of 7 for 9 is GOOD. So in order to make Nezzy "hold on" to his Queen i set that at 10.3 while leaving the opponents at 9.....that way Nezzy rarely trade's Queen's but once in a while like the guys said above......he may not play the BEST variations. and here and there u see him trade his Queen but MOST times it would rather give up a pawn b4 trading off the Queen. I think that helps it maintain its attacking chances at times. 

Thanks for the clarification. I'm still setting up the Arena files. The reason it's taking me so long is that I'm trying to set up ALL of the Chessmaster GM personalities in Arena. Obviously, I'll probably only use a few GM personalities in any one tournament, but I want to have the ability to choose any GM personality from the Chessmaster list.

I've already converted all of the Chessmaster opening books to abk format, and I've converted the GM photos to the Arena landscape format. The next task for me is to convert the Chessmaster personality settings to Arena format.

For information, when running the GM personalities in Arena, I'll have to make a few minor changes to the settings. They won't use endgame tablebases, because the King engine can only use tablebases when it's running in the Chessmaster GUI. Also, I usually use a hash table size of 128 MB for all engines running in Arena. And finally, I always turn pondering off when running engine tournaments in Arena. I doubt that these changes will make significant changes to the performances of the personalities.

you can already i had that problem too.....when setting up a tournament......just click the button that says "my level" and THEN set the number range from 0-2999, Then u can put Fischer vs Nezzy and so on. I've already run a few tounrneys that way and Nezzy did ok

I had the SAME confusion it took my buy ANOTHER copy of Chessmaster to figure that out.......i was in the c drive trying to rename files......i messed up Nezzy and had to re install it.......thank goodness i had a template.....i dont think i would have remembered all those parameters. Cuz each change actually changes its playing style a bit. U cant do this with Stockfish or any other engines........that's y i think this one is MOST user friendly and the best. 

so funny i did the SAME THIng......i went in and and just backspaced a letter or two in the info section of EACH GM tab.......which was time consuming until i accidentally did what i just told u to do......and you can use ALL personalities as well as GM"S on the program. Fischer vs Nezzy.......Anand vs Nezzy......Petrosian vs Nezzy.......Nezzy has managed a draw vs Petrosian but i dont think he has beat him yet. But he beat Timman....Fischer.......Bkackburne.....Spasky(huge surprise) even beat Anand so itcan play in CERTAIN positions  i luv my little creation 

VERY interested in the results and i dont mind running a few of the games for you so you dont have to run ALL of them. Just let me know the parameters and i'll run the games and post the pgn's. U gotta tell me EXACTLY how u want it done tho so its ALL consistent.....keep me posted

Yeah, I *could* run a tournament in Chessmaster 10th Ed., but there are a few drawbacks to doing so. Every single game in the tournament has to be started manually, and that's just too laborious. I want to be able to tell the GUI how many games to run, then be able to walk away from it. Strangely, Chessmaster 9000 didn't have this "single game" limitation.

Also, the CM10 GUI doesn't display any analysis in tournament mode. I like to have at least a minimal amount of engine analysis during engine tournaments.

There must be something wrong here:

Look at how ridiculously low is my chess.com rating, never got over 1500.

But Im beating chessmaster on my computer at grandmaster personalities. My computer is an Intel i7 (8 cores 2,4GHz), 16GB RAM. Im playing 60 minutes/game. Chessmaster Grandmaster edition. The game says chessmaster personality is 2980 rating.

That's completely wrong, I can't be better than Magnus Carlsen! So I thought this chessmaster is broken or full of bugs or something.

I play Stockfish 10 in arena at full strength. It crashes me, just as expected.

So chessmaster rating is not what it says. Not even close.

Reading this thread I just learned about "analyse your games app". I introduced a match I played vs stockfish 10. I configured stockfish at 50% strength. According to this app Stockfish was 2300 rating and I was 2400 until I lost in middle game, in which I became 2100. That still cannot be possible.

How can we really know our rating? How can we know stockfish rating in arena (or Fritz)?

Yes, something is definitely wrong with your setup. According to the CCRL 40/40 rating list, Chessmaster 11 is rated at 2664 elo.

Thank you for the link. Actually that website has been in my favorites for years

But I don't know why it's name in the engines list is "grandmaster" instead of "The King".

Anyways, i'll check the set up of the game just in case. I never touched any slider though.

An important thing to take into account is that Chessmaster rating changes itself automatically according to the computer in which it's installed. In my other computer the chessmaster personality rating is lower because that computer is worst.

Which is the reason I trusted the chessmaster rating

Another thing to point out is that the microprocessor in CCRL is worst than mine, that's the reason I thought the higher rating of chessmaster in my computer was correct

No its not that its judging your rating wrong.......its like this.........in a 30 move game.......you might make 5 GM level moves.......20 (1500 level) moves and 5 blunders. but these can be spread ANYWHERE thru the course of the game. Say your 5 GM level moves are in the middle game......your mid level moves are in the opening and a few moves after.......and then u got 5 blunders in the endgame....for a loss  That is how i think the computer judges your rating. There was a game i played in the King's Gambit Accepted. I am ALSO a 1500 level player. So i played the Muzio Gambit where you sacrifice the Knight of F3 if the opponent pushes the g5 pawn to g4. I sac'd the knight and got to a position where the attack was fizzling out..........the ONLY way to keep it going was to sacrifice ANOTHER piece. I could NOT find another move that would allow me to keep attacking. I eventually won the game......and when i reviewed it with Stockfish.........from THAT SACRIFICE onward........AS WELL AS the sacrifice of the SECOND piece.......i played EVERY MOVE Stockfish recommended until the end of the game. So technically speaking in THAT game......for those 10 moves.......i played like a Grandmaster......in fact a bit stronger than the STRONGEST GM for about 12 moves against a 1700 level player. It doesn't mean i'm a GM or anything close to it......it just means that in THAT position.......for 12 moves or so.....i picked the SAME moves the BEST chess engine would pick.......kinda sucks for my opponent lol. The other thing to consider is that it was an open position that lent itself to tactics........i dont always find 10-12 moves in a game where i am playing so good.......but i DO like open positions and i can play them decently. 

That clarifies many doubts I had, thank you

This thread is very interesting, I always wanted to know if ELO could be measured using chess engines instead of going to rated official tournaments

Im not sure, but I think randomness just makes the engine perform a random move. More randomness will do the some more times. Usually a random move will be a bad move. That's just my guessing of how it works I don't know for sure.

When I Played chessmaster at grandmaster levels I always checked randomness was at minimum, because I don't think random moves by them would be realistic (in a rare case at most).

Anyways I never touched the sliders, just checked it.

@p8q(That clarifies many doubts I had, thank you )

I think to some degree you can measure your general playing strength with those engines. You can analyse how many blunders you made. Like on Chess.com they point out CLEAR blunders.....you can check inaccuracies and you handling of openings. I think its kinda hard to make an abstract measurement of someone's playing strength.....which is why i like how ChessMaster describes the personalities. Some ppl are GOOD in the opening......WEAK in the endgame and STRONG tactically. they will rip you apart in the middle game but if you can survive they might fall apart in a drawn out end game. Some ppl play VERY well in the endgame and in slow boring positions...D4 systems etc........but as far as speculative sacrifices and exiting tactical play where the balance rests on ONE single error and FLAWLESS handling of the postition.....they just CANNOT manage it. So when i look at a persons skill level......its not just TO ME AT LEAST at this was influenced by Chess MAster.....its not just his rating but the breakdown of the various situations in Chess and how each person handles them. I LOVE Nezhmetdinov but i ALSO like Petrosian who could make exchange sac's and hold on for a draw where you thought you had him.......this ALSO takes good tactical play and understanding of the position.

response to #82....yeah after watching Nezzy play a bunch and i know u werent a part of this aspect of the discussion but i think you are right. Randomness boils down to a bad move for the most part.......i was hoping to make the engine expolore some cool lines and variations but i  find it just plays poorly in the endgame or sooner if u play with that randomness functions too much......and i ALWAYS played with those parameters.......the MINUTE i saw you could do that i used to do that to ppl on Yahoo Chess........i had a profile that would sac its Queen......i let it lose tho becasue i REALLY wanted to see how good it was........on THOSE parameters back then which i dont remember but low queen value around 6-7......it was ONLY about 1750 or so.......NEVER got much higher than that ......it would STRUGGLE to beat an 1800 on Yahoo chess and no disrespect......i find an 1800 in Yahoo chess with 25K+ games played was about equal to a 2000 level guy on Chess.com.....YahooChess from what i remember was more gritty and gangster. If you were a 1500 on Yahoo chess you were a REAL 1500.........if ur 1500 on Chess.com i'd say ur about mid level 1300's on Yahoo Chess.......the had some GOOD players on there.....BadgerBridge......SO MANY deadly lounges.......only the strong could survive.

@p8q - Ubisoft tried its best to prevent "The King" engine from being used outside the Chessmaster GUI (using OPK codes). That's probably why the various terms like "Chessmaster Grandmaster Edition", "Chessmaster 11" and "The King 3.50" tend to be used interchangeably.

Regarding estimating the engine strength - You could get an estimate by going to a web site that benchmarks different CPUs and find out how many doublings of speed there are between your CPU and the CPU used in the CCRL rating list. A good rule of thumb is that for every doubling of CPU speed, there's about a 50 elo point increase in strength. Of course, these are only estimates.
