Lucas Chess engine settings are very weak - Chess Forums - Page 3

Eh, earlier today I restarted the Arena tournament again. I'm usually not this fickle, but I didn't like how I'd set up the tournament. I didn't have a good idea of two of the engines' strength (Clarabit 1.00 32-bit and Gibbon 2.01b).

I've expanded the number of engines from four to six, so it will take longer to get good results, but the four non-Chessmaster engines all have lots of games played on CCRL. Those four are: Bestia 0.90, Gerbil 0.2 64-bit JA, Matheus 2.3, and Wing 2.0a.

And yes, there are now two Chessmaster engines: Chessmaster 10 Vanessa, and Chessmaster 11 x64 Vanessa. Unfortunately, the CM11 x64 Vanessa doesn't have the OPK patch, so every time I reboot my PC, I have to generate a new OPK value. (It's not THAT much work; It's just remembering to do it.)

I'll give you an update when I have results worth mentioning.

Engines with 2100 of fixed elo have a handicap set by the author of the engine, normally the number of positions analyzed per second is limited.
Lucas Chess only sends the command setoption name UCIElo value 2100 to the engine.
When depth 3 is set, another limitation is added, the engine is instructed to analyze only to depth 3 in each movement.
There are two limitations, and only the most restrictive has effect.

To play against a 2100, it is preferable to remove the depth option (-- as indicated by EscherehcsE), and play for time (there is a tab to indicate it).

And the biggest problem with engines is finding out with less than 2000 of it and running properly, almost all engines have an elo superior to 2100, of course it is playing without limitations.
In the next version 11, there will be 33 engines with an elo greater than 2500, and 9 with an elo greater than 3000. I don't think it's necessary any more, perhaps they are more interesting those that have a minor elo, for the majority of the users of the program.

And thank you for your interest in the program.

Hi Lucas, thanks for responding. However, I'm still trying to figure out this issue. I selected an "Engine with fixed elo", specifically McBrain 2.1a (elo 2100). I set the depth to "--", and I left the time as "0.0". (The time control for the game was 6/2.) After doing this, the engine appears to be running at full strength. It beat engines rated in the mid 2500s. I even tried the same thing with McBrain 2.1a (1200 elo), and I swear, it still seemed to be running at full strength. Is there something I'm not understanding about these settings?

Lucas Chess 11.01 was released today.

The problem I was having with McBrain 2.1 has been fixed with McBrain 2.7 in this latest release of Lucas Chess.

Thanks Lucas!

can we export the engines of lucas chess to Arena or Rybka(fixed elo or internal engines) so that we can make a custom tree on rbyka and train the opening from the tree? And it would be nice if lucas chess announce move for playing over the board for training purposes cause playing games looking in the screen is tiring and not productive.

Hi,

In a tournament between engines I set an initial position, the FEN is:
8/8/8/8/1Q6/1K6/8/2Nk4 w - - 0 1
when is finished the game can't close the windows, can't close the Lucas Chess. How can I close the software?

Excuse my bad English!

It works perfectly on my Windows 7 system. I don't know what to tell you.

I won kasparov and carlsen engines easily!

kasparov engine blundered his queen in opening while its rating has written 2830 or something

stockfish11 tutor was helping me too but kasparov engine should not blunder queen easily in opening

When you pick one of those profiles, from what I recall there is also a level adjustment. I usually play the Tal profile at intermediate level.

I'm not sure what the different profiles do. I think it's more of a gimmick. I imagine that they try to duplicate the players style, (sacrificing vs defensive vs attacking etc). But at the highest difficulty on a decent laptop they should all be very hard, or impossible to beat

it was on depth 3! that is why they were playing bad. i changed it to (-)

is there any way to create tournament between GM engines like fischer kasparov and carlsen?

I don't think there's a way to do that - only normal engines without personalities. At least I wasn't able to find a way to do it.

what does engine priority mean in the analysis part? (it has normal, low, very high... options)

and "is considered the wrong move when the loss of point greater than: part was on 50 but I changed it to 100 because It was finding so much blunders. what is the best number for this part?

My version says bad move =90, very bad = 200 which are the defaults and the defaults work fine for me
