# Ponder ON or OFF ?

What is more real and effective when you do a test between 2 engines and Ponder Ponder = OFF or ON?

Example: Engine with 4 cores

Use 2 cores for each engine, Ponder = ON with double play time ?
Use 4 cores for each engine, Ponder = OFF?

I hope that some expert clarification.

Thank you.

"Current programs cannot create strategic plans, so a program simply tries to predict the opponent's move and begins to calculate its response. If the opponent's move has been guessed correctly, then the program continues to calculate. If the prediction fails, the program begins a new computation.

Pondering is less effective than normal thinking. For example, if the program guesses 25% of the opponent's moves correctly, the use of pondering is on average equivalent to increasing the normal calculating time by a factor of 1.25.

In chess games between two computers, pondering makes sense only if the competing chess engines use separate processors or cores. If they share the same core, the pondering program steals half of the time from the program thinking in the normal way and uses the stolen time less effectively. For this reason, chess GUIs have an option to turn the permanent brain off."

In my case i have 16 threads available at disposal, with pondering enabled 8-cores each. Is it advisable to enable this in blitz matches?

You could do that if you wish, but hyper threading will only degrade the amount of performance per physical core.  Since 5960x has 8 physical cores and not 16 physical cores, you would need to enable your engines to ponder constantly on 4 cores for each.

Pondering is only effective if engine A successfully predicts engine B next move. If unsuccessful, engine A must begin new computation which many have agreed to slow the efficiency of the overall evaluation process.

Thanks for clarifying this. In this case the raw calculating power for each engine will be halved in favour of in-directly increase the total time, as a result of predicted moves.

Yes, you will in affect increase the amount of thinking time by a factor of two (2), decrease the raw processing power of each physical core by a factor of two (2) since assigning 8 additional virtual cores requires physical core processing. Thus, virtual threading becomes inefficient because you create more pathways for the engine to the processor therefore more needless precesses (unless you are using two different operating systems on the same computer).

Hi QueensideCastler

Your game above is a Classic example of Chess Engines not being able to Plan! a Wining idea,I have found that a Minimum Speed of play for Engines should be (60) Seconds each per move then they have more chance of getting a Grip on the Position where they can make some kind of progress! otherwise they tend to Shuffle Pieces around when facing a Stand off!
Try a Match with the Two Engines above at least (10) games alternating White & Black you should see much Shorter & more decisive games ? even if they are draws!
An interesting idea to Stop long Book lines which can lead to an unfair Advantage :( is to turn the Opening Book off and Start each game Alternating with the first Moves only! (Entered by you) so that the Engines are thinking at Move ..2 Example 1.e4 Game each 1.d4 Game each 1.c4 Game each 1.Nf3 Game each and 1.f4 Game each :) is always Interesting.

I think pondering have it's usefulness in low time controls like blitz, even if they share same cores. In my case i had to turn off hyper-threading in the bios because according what people say it only degrade overall performance. 16 threads to 8 physical cores.

"If they share the same core, the pondering program steals half of the time from the program thinking in the normal way and uses the stolen time less effectively"

the use of pondering is on average equivalent to increasing the normal calculating time by a factor of 1.55.

Still not sure if it is advisable.

Pros:
Both engines thinking continuously
Predicted move ratio is over 55%

Cons: Decrease raw calculating power from 8 to 4 cores (50 % penalty)
In other words my total kilo nodes per second is divided by 2.

Ponder On if fine :) I always Test with Ponder on...When an Engine is thinking along the Same line as another Engine which is most of the time...it can lead to some Very Deep calculated moves where as Ponder Off will miss it!

Are you sure it is any beneficial in longer time settings?

From my experience, it is not beneficial. It will waste your computer engine time control and resources. The statistical probability of the opponent engine anticipating the correct move is about 25%. With half of your processing resources used in continuous pondering to the other engine, you are reaching only half the depth for both engines search for the correct reply. So in this sense, you would need to ponder twice as long or constantly ponder to reach the same performance of rotating full processing power between two engines.
Komodo won both games with each color, with permanent brain enabled. Now let's see how the game results turn out if i increase engine power to 100%.

Ponder On if fine :) I always Test with Ponder on...When an Engine is thinking along the Same line as another Engine which is most of the time...it can lead to some Very Deep calculated moves where as Ponder Off will miss it!

Are you sure it is any beneficial in longer time settings?

From my experience, it is not beneficial. It will waste your computer engine time control and resources. The statistical probability of the opponent engine anticipating the correct move is about 25%. With half of your processing resources used in continuous pondering to the other engine, you are reaching only half the depth for both engines search for the correct reply. So in this sense, you would need to ponder twice as long or constantly ponder to reach the same performance of rotating full processing power between two engines.

The "anticipating the correct move is about 25%" is way too low! the Best way to get a Confirmation is to use the (Tools/Analysis/Compare Analysis) using a Group of different Engines) in the Fritz GUI then you will see how many times each Engine agrees with the others! :)

W.C.N

25% is indeed to low.

"According to Robert Hyatt, in about 50% the prediction is right"

"Pondering is less effective than normal thinking. For example, if the program guesses 50% of the opponent's moves correctly, the use of pondering is on average equivalent to increasing the normal calculating time by a factor of 1.50."

Different as night and day between 1¼ and 1½.

In my engine matches the predicted move ratio is in the range between 50-60%
The Best way to get a Confirmation Regarding (Moves Engines play the same) is to use the (Tools/Analysis/Compare Analysis) using a Group of different Engines) in the Fritz GUI

Below is an Example using (5) Different Engines for a Famous Computer v Computer Game Hitech v REBEL 1986
Hitech was a Mainframe Computer and REBEL a PC

Just see how many Moves they Agree on :)

25% is indeed to low.

"According to Robert Hyatt, in about 50% the prediction is right"

"Pondering is less effective than normal thinking. For example, if the program guesses 50% of the opponent's moves correctly, the use of pondering is on average equivalent to increasing the normal calculating time by a factor of 1.50."

Different as night and day between 1¼ and 1½.

In my engine matches the predicted move ratio is in the range between 50-60%

It is still an exercise in futility. Let's say the move prediction is 50%. Both of your engines would still be reaching the correct response line half of the time in the time control and in the other half will have wasted considerable time finding the wrong move for nothing to gain from it at only half of the potential depth. Your engines might agree on the same predicted reply at 15ply for example but may change course once 30 ply is reached. An exercise in futility.

So in a nutshell the Core-penalty outweighs the time factor?

Read my last statement but more carefully this time.

If you really love pondering, I highly suggest you set up two computer match :) "There are some who feel that Pondering should be set OFF when testing on one computer. This ensures that when it's programs A's turn to move we can be sure that all the computer resources are used by A and A alone"

You have some Good examples above! with Ponder ON :) as I have Stated the Best Engines Search the Deepest like Stockfish Where Strong Engines Guess the Other Strong Engines moves about 60% of the time! that's a 10% Advantage for Stockfish because it Searches the Deepest! Rather than hoping for a 50% Ratio Where it may not be such an Advantage.
