Hello, Ive been using Rybka 2.2 on Arena 3.0. I dont know how to change the Elo. Can you tell me?
Hello, borsli. Changing the elo is a very lengthy and difficult procedure, but I'll do my best to lead you through it.
In the Levels menu, click on "Limit Playing Strength to ELO...".
I clicked "Levels" but couldnt find any "Limit Playing Strength"
Oh, I found it, but it wont let me click it.
OK, if you start the engine, then stop the engine (try turning analysis on and off), you should be able to click on "Limit Playing Strength to ELO".
Ok, I got it. It seems that I can only set it to 2400. I thought Rybka was at least over 2800?
When you limit Rybka's strength, you can set it between 1200 and 2400. If you set it to maximum strength, it will play at full strength, much higher than 2400.
By the way, the real playing strength of these engines at these lower levels are often not too accurate. I think that this 1200 elo Rybka plays considerably stronger than a real 1200 person.
Ok, s that the only way? Is there another way to change the Elo?
Yep, that's really the only direct way to do it. You can also go into the engine configuration and change the CPU usage to between 1% and 100%, but that's not a very desirable idea, because it just shortens the engine's calculating time, and you have no idea how much it's going to reduce the elo level.
And you can do both if you want to...set the engine to 1200 and reduce the CPU usage.
One last question, what's the strongest free chess engine right now?
Probably Houdini 1.5.
Hm. How do I stop the engine?
If the Analysis button is on, just click the Analysis button off. Or go into the Engines...Engine 1 menu and "Stop calculating". Or right-click your mouse in the engine analysis window and "Terminate Engine Process".
If the engine is thinking during a game, you could resign or pull the plug on your computer.
Have fun with Arena!
Here's an article on the TOP TEN free chess engines
On a slightly related note, is it possible to change how 'random' the engine's move is? For example, instead of playing what the engine considers to be the absolute best move in every position, it plays any move that has an evaluation within .5 points of the top position?
For awhile I stopped providing the following link because some peeps took it as a personal insult. It's not an insult, it's actually very handy to help people help themselves in looking up the answers to relatively esoteric questions (like the ones here) www.cln.org/searching_faqs.html
