when i use rybka 3 yesterday, only instant moves available. she doesn't need to think at all no matter from move 1 or move 40. i'm scratching my head for the past many hours on how to set it to perform better than rybka v2.3.2a

You obviously have to provide much more data for someone to help you.  What GUI are you using?  Did you change any engine parameters?  What settings have done?

i'm using shredder 9. previously i'm using rybka 2.3.2a. i straight away install rybka 3 1-cpu 32 bit. i didn't change any setting. then i started a new game n also my previous games. rybka 3 do not to think at all. it'll move within 2 seconds. depth = 0, Kn = 0, time = 0. everything also 0 or blank

Did you set a time control level?

Instant, or almost instant moves would be typical for small fixed depth levels.
Parent - - By ronyjarod (*) Date 2008-08-12 08:05
time control as usual = 99:99:99. i change nothing at all from my previous settings

What exactly are you doing? For infinite analysis, you need no time control at all. Just switch to analysis mode. Your time seems to intend infinite analysis, but is very uncommon. Maybe Rybka cannot handle such a strange setting. For games, please use a normal time control.

How could you run games with Rybka 2.3.2a, with a time control of 99:99:99?! This seems impossible.

(Btw. 99 minutes or seconds is illogical; max. should be 59)

i tried infinite analysis just now. it's still the same. only instant moves
Parent - - By ronyjarod (*) Date 2008-08-12 08:19
but for my 2.3.2a, the above clock is shown 99:99:99, then it'll runs like a countdown clock
Parent - - By Permanent Brain (*****) Date 2008-08-12 08:27
I didn't mean the clock, I meant the playing level, set by a time control (like 40 moves in 2 hours or whatever).

It is not possible to get 99:99:99 on the clock, in a Fritz interface. Maximum I can get is 25:15:39 (25 hours).

Again, 99 minutes are nonsense. 60 minutes are an hour.

ok, now i understand. i set it to long game. so it'll be 99 days for the whole match

in a sudden, infinite analysis is working now. but there r 3 lines. 1st is 0.83, 2nd is -2.26, 3rd is -8.16. i don't understand those. till what number should i stop?
Parent - By Felix Kling (Gold) Date 2008-08-12 12:06
are you sure you are really using Rybka? :)
Parent - By Arkansaw (***) Date 2008-08-12 13:02
er....are you sure you know how to use chess software?

There are a few interesting issues.

1) Some of your former posts suggest that you have little to no experience with using modern Chess software.
For example: you claimed that "even infinite analysis used to move instantly, and all of a sudden, it's working.
Quite impossible, because of one simple fact:
Infinite analysis NEVER moves. At all. That's the whole idea, it analyzes and analyzes until YOU make a move (perhaps based on the analysis results), and then it starts analyzing the new position for as long as you leave it on it.

Unless you meant something different.
If you mean Infinite analysis never really played the move, but just didn't change the analysis after the initial one, then that's another problem.

The basic features (and all the features you describe are very basic) are pretty much the same for all modern Chess engines and Guis. Reading Shredder Gui's manual would really help, I'm sure. That way you can be sure if you're doing something wrong in the Gui or with Rybka's features.

2) There are two options for the 3 values:
Either you (or someone else) accidentally, without noticing set the PV (or multiple variation) paramter in Rybka's UCI options to 3. That would cause her to display the best 3 variations instead of only the best one (but is somewhat slower).

Pretty much Every modern engine has that feature.

Another option is that you are confusing 3 variations with the same variations at different depth, since the variation the engine suggests is presented with its updated evaluation on each depth.
This option is unlikely, however, because the 3 scores you give differ too greatly.

However, if you could post the position for which you got these values (or, better yet, a screenshot of the problem being reproduced), I could give a more educated and accurate answer.

3) "1st is 0.83, 2nd is -2.26, 3rd is -8.16. i don't understand those. till what number should i stop"
You don't understand those? Rybka 2.3.2 (which you used, according to your posts) was evaluating positions in the same way. Also Shredder, and every other engine, give the output in such numbers.

for most engines/guis/settings, a plus score means "better for white", minus means better for black, and the exact number states by how much (according to the engine).

How did you handle these in the previous version? They were there too.

4) (Apologies in advance if this does not apply, you are NOT being accused of anything)
I've seen strange Rybka behavior reported by two people I know. In both cases they downloaded the program from somewhere instead of buying it, and, as so often happens, got a fake, that only claimed to be Rybka.

A quick comparison with my own Rybka on the same positions convinced them to buy it.

I assume you have bought Rybka. If so, you are obviously doing something in a different way than it was meant to be done, and we find it difficult to help you, because we do not understand what exactly are you trying to do.

Please explain, why is infinite analysis not good for your purposes, but a 99 days match is?
What is it that you are trying to do? If we can understand what you're doing, it will be easier to help you.

infinite analysis is not suitable to me

What are you trying to do?
Parent - By ronyjarod (*) Date 2008-08-12 13:06
i just do not want rybka 3 to move instantly cause she isn't thinking at all. previously i'm using 2.3.2a n it'll start analysing with depth n Kn n time
