Ponder ON or OFF ?

The main difference between you and me is that I know what rankings, and what tournaments I have won over the years. You on the other hand, just THINK you can play
because you waste your life away digging up pointless facts about chess which you then consider makes you a chess player.

You are not even worth the effort.

It may be an idea if rather than wasting your time thinking about chess you went back to school (if not there already) to learn a little more about English grammar, that would be more useful

Pondering is simply using the opponent's move time to consider likely opponent moves and thus gain a pre-processing advantage when it is our turn to move, also referred as Permanent brain :)

Whether to use ponder off or ponder on is entirely the user's choice.
Personally I find ponder on much more interesting, even though all my CCRL testing has to be ponder off.

However, in relative terms, there is very little, if any, overall difference in terms of strength. There was a prolonged experiment carried out a number of years ago that showed this. If I can remember who it was or find a link, I'll post it.

If the Experiment you mention was done so long ago before better Engine Algorithms used today that can Search much Deeper that have pushed the Engines up to (3300)+ ELO then it may not be so Relevant ?
As I have mentioned there are some Positions where if Stockfish is Not using Ponder ON then it misses the Winning line!
Maybe a collection of such Positions would be a Good idea :) which may Nail the Ponder ON or OFF decision once and for all! And just as important if the Same applies to other Engines ?

Does anyone have some Positions where a Single move has changed a Game Score very Quickly for One Engine getting a Big + Score ? and maybe even Some Mikhail Tal Winning moves if found by the Engines could do it :)

I read somewhere that pondering is equivalent to increase strength by 30-50 ELO with proper setup and conditions.

I Can believe that :) and I believe the (60%) Guessing the same Moves as the Other Strong Engines with Ponder ON is going to Increase! the reason I believe it is because I see all Chess Engines being made in the same way Now that the Blueprint has been made...there will always be some slight differences but the Target every Engine designer is aiming for is to make the Most efficient & Deepest reliable Searching Engine possible! Just as you see all the time with lot's of Creative Calculated problems Humans end up with the same end product!

Though engines have been created and written in virtually the same code, the programmer has sought to find ways to improve on the evaluation capabilities of the engine and not just the depth of the search (which is responsible mainly for more aggressive pruning and Late Move Reductions). Engines themselves will inevitable search deeper and faster as hardware and software improve over time. So speed and depth of computer chess is unavoidable. What is left? Changing the evaluation code to be better than it was before. Why do people think that creative  calculations offer the same cookie cutter solution? It is (in my opinion) because people have abused the open source right to copy and paste their ideas in whatever fashion they like (and they have the GPL right to do so) and slap a name on the engine call it King of the Hill. However, this does not in any way mean that all roads lead to Rome (in this case).

I Agree with a lot you say Nathanael the Problem is that if a Person thinks Outside the Box too much ? and tries to avoid the Straight Single line approach (which is the Shortest root to Solve most Problems) then their Engine will Suffer in other ways!
And I am sure that's the Reason famous Engines like Fritz,Hiarcs,Shredder,Junior, Etc. have not moved on is that they are Still using Outdated Engine methods because that's how they have always done it! Trying to get a Programmer to change their ways to a more Modern way is a Very hard thing for them to do! (I also suffer from it :) ) I program in a certain way that is not the most efficient but I trust what I do! it out weighs the risk of going along lines where I feel My Programs may Crash Etc.  But if I was in the Competitive World of trying to compete with the latest Engines I would have to go back to Square one and Start again! I recently Contacted the Famous Engine maker Richard Lang Pleading with him to bring out a New Version of Chess Genius to show these upstarts how to do it :) and he Replied that the New Engines are for a Whole New Generation of Programmers...basically saying that he had his day when he did!

Now you understand why as much as I adore Stockfish and its magnificent Fishtest Network (I was a supporter when enthusiasts said it was a Rybka derivative), I hope one day there will be an engine with code enough to destroy Stockfish and once again open the opportunity for other developing programmers. That is why I applaud Komodo that Don Dailey envisioned.it is a testament to thinking outside of the box

Watch this Space "The A.R.B Chess System" Engine may be on it's way :) but there are some Problems with getting it to think in a Human type way :( you would never believe how hard it is to get an Engine to Move just a Pawn up one Square for a long term Strategical Advantage...rather than trying to capture another pawn for a Short term Advantage Etc.

Another method for making pondering useful is by using a dual socket motherboard. Two identical processors like for example i7-5960X. This allows 8 cores to be running continuesly (Hyper-Threading disabled).

Very expensive but you get what you pay for!

What is the view regaring dual socket mobo and identical CPU's`?

I could do this on my octal if I chose to, as it has a dual socket motherboard.
You could pick up an older motherboard and chips fairly cheaply I'd have thought.

A simpler way to think about it might be to consider the engine's "strength" as a percentage of its maximum strength. Without pondering, each engine plays at 100% strength. With pondering, each engine plays at 100% strength during its turn and 25% strength during the other player's turn (assuming 25% accuracy in pondering guesses), but each turn is half as long (because only half the CPU time is available). So with pondering, the overall engine strength is only 62.5% of its maximum.


How about this scenario - my CPU is 5960X (8 physical cores) if i enable ponder 4 will be asigned to each engine. From my engine testing the predicted move ratio is much higher than 25% it is actually in the 50-60% range, most often 58-63% so lets make it 60%. Can you calculate the difference in performance between 4-core ponder and 100% CPU resource.
 
Assuming same engine, fixed time per turn, each engine able to use all cores at 100% if available, 0.5*100% + 0.5*60% = 80% –  intx13 16 hours ago
 
In general you can estimate the new strength as 50% + 1/2 * (predicted move accuracy). But this becomes less relevant the more you move away from the theoretical scenario I described in my other answer. If you were running two different engines with no per-move time restriction and those engines might not use all cores to 100% during normal operation, this estimate is meaningless.


It looks like with 60% ponder accuracy it comes with an 20% penalty in overall playing strength, if shared cores  think

My 5960X is no exception sad
