my stockfish on scidvspc doesnt have the problem as qouted by analyzethis pgn and EscherehcsE. It works fine for me.
SCID vs PC
Sort:
I have no idea what the quote is.
It seems the bug appears when you turn on permanent brain.

Which version of Scid vs. PC are you using?
And what is this "click on the quote" you speak of?

Scidvspc 4.11.

what should these settings be set to. For example is the current setting of 20 considered high or low
and
what time control and thinking time should be set.
i normally play 30min games and occasionally 90/30. does the 30min time control limit how strong or what depth the engine can think.
MOST players, including me, usually leave most all these settings alone, and leave them at the program defaults. But there are a group of players that love to tweak them, in an attempt to get more out of the engine. I myself have never touched SPACE, or PAWN STRUCTURE ENDGAME, for example.
The higher the number, the stronger the setting. Unless you want to dumb-down the engine, SKILL LEVEL should be left at 20, for example.
Notice this version of Stockfish only allows one thread. There are development versions of Stockfish that allow 8 threads. The more threads, the better, of course.
As far as time controls that you use to play against, that's up to you. You can give yourself more time, or an increment, or both, to give yourself more of a chance against the engine. You can give the engine a max of x number of seconds per move, or give it a fixed depth. Playing with these Configure UCI Game options, along with the UCI SKILL LEVEL setting, should allow you to find a combination that will give you a competitive game against the engine, if that's your goal.
(When I play against the engine, I don't like to dumb it down. I want it to crush me, so I can learn how to to do the same thing to others.)
I haven't read every post in this thread so I apologize if I'm missing something. Anyway, I want to clarify that Stockfish DD defaults to 1 thread, but you're not limited to that. For best performance you should manually change the number of threads from 1 to how ever many real (not virtual) cores you have.

Oh, the Chess.com forum quote feature. I thought for a minute there was some Scid vs. PC quote feature.

Have you tried turning on permanent brain to see if the bug appears?
@ EscherehcsE : Yes, I did try just now, after your suggestion. And it did make silly mistakes, even at full strength. And I could beat it !!!.
> do you think the lack of the Ok button is the problem
Yes. Change the font size to get the Ok button. (Options->Font->Regular). The issue of the config widget not fitting the screen has been fixed in subversion. It is now a scrollable canvas.
> When you press Play Computer-UCI engine a dialog windwo opens and the default thinking time is 6 seconds and search depth is 3
Search Depth 3 is obviously the problem, and something you have set sometime yourself.
@stevenaaus : when i analyse a game with scidvspc, i just hit enter after clicking the annotate button in engine window. I also dont get the ok button, but hitting enter works fine for me.
Thanks Steven thats a great help,
I have set the font to 7pt and clicked ok button. the analysis started so im just waiting now for it to finish and ill let you know here how it went.
As regards playing the computer UCI. what depth should be set for the computer to be at full strength.
what combination of game time , thinking time and search depth is best.
Hmm - i'm not sure how useful my help is.
Fixed depth being 3 does not actually matter unless the Check-button is pressed. edit - The Stockfish engine doesnt log in this mode either, but start it in analysis mode and send me the log.
And just Pressing Return also works fine for me, so not sure how to help.
cheers.
well you said the ok button does matter so thats help for a start.
i satrted the analysis 6hrs ago at a depth of 30. its only on move 10 now. i dont like leaving computer on all night for it to finish.
what setting would you recommend to get a decent analysis but wouldnt take all day or night to finish
Today's engines are very, very strong. You can get what is probably a MORE than adequate evaluation of any position after just a few seconds, with the speed and power of your average computer today.
If you don't think that's enough, then go ahead and have the engine evaluate each position for a full half a minute or so. But that should be all you need. That should be MORE than enough time for your purposes.
If you don't think so, then run some tests. Evaluate a dozen or so different positions for 30 seconds, and note what is the best move and score. Then, evaluate those same positions but now for a full minute or two, and again note the best move and score.
I'll bet a large percentage of the time the score won't change very much at all, and the best move will still be the same.
At some point, evaluating a postion for too long is just overkill and a waste of time. If you're analyzing to a depth of 30, I consider that way too much. Like you said, it will take all night. And so what if it finds a different move at depth 30? The move it found at depth 29 was a good move too.
I don't know your strength, or your purpose for evaluating these games, but I'm guessing that you can EASILY have Stockfish or Critter or Komodo or Houdini or Rybka (or any of these strong engines) evaluate the positions from your games by spending just 20 seconds or less to do so.
Thanks Ed, Im new to using engines for analysis and now that ive got Scids analysis working I just needed some guideline as to how to use it.
Ill set it at 20s
I agree. Common sense tells me that the difference between the best move at a depth of 25 moves vs. 30 moves is totally in computer territory and far beyond my ability to utilize the difference. Additionally, unless you're playing against another engine, you opponent will never follow the best response lines getting to that infintesimal advantage your engine found at move 30. Such depth in analysis is overkill for humans.
what should i set the threshold for in the Add Variations section in the annotation window
and what should be set for blunder threshold. i have it set for .5 atm.
is that too low

You can set both to whatever you want. It's up to you. It's a matter of personal preference.
No, .5 is not too low. It depends upon what your purpose and your goals are. If you just want to review your LARGE blunders, for example, then yes, .5 is probably too low. If you're just looking for big mistakes, you might want to set it at 1 or 1.5, for example.
But if you're an Expert or Master, and you want to know when the engine thought you made even a small error, then you might set it to .4 or .3 or lower.
You have to experiment. Set the blunder threshold at .5 and see what type of analysis you're getting. Then set the threshold higher (or lower) than this and THEN see what type of anaylsis you're getting.
