Stockfish 12 is available, and surprise surprise it includes NNUE (efficiently updatable neural network) out-of-the-box. It would be significantly stronger than its predecessors.

Did anyone try it in deep already? Any thoughts?

not that good in corr chess for now, because the network is not good enough

Now it tops CEGT rating lists, 40/40 and 40/4

On Larsen openning, SF 11 find theoretical moves, not SF 12.

By the way, if SF 11 finds these theoretical moves, it can find it kind of "luckily"... it does not mean with certainty that it finds it "better".

I do not put much faith in CEGT rating lists. What those rating lists measure is engine play v engine play.

Whilst that can be interesting to see if any 'newcomers' or updates are worthy of consideration, for our purposes of correspondence chess analysis, engine v engine play has some major limitations.

Tried downloading this engine. After trying the first three options, could not get any of them to work.

What options do I need to select to get this engine to work?

Usually I choose the executable with BMI2 set up. But for SF12 I've choose SVX2 version.

I've Install it on my old Fritz 11 GUI and all SF version work very well on it.

If you can't use the executable, you must have a very old computer. On wich GUI have you try to install it ?

Hello Stanislas,

Thank you for your reply and assistance.

I believe I have been able to solve the issue and it was more simple than I thought.

I was thinking that my attempts to download SF12 and use the engine were being thwarted due to issue with the Neural Network.

But I re-downloaded the engine, loaded it and then changed the parameters and it now loads just fine.

I use Fritz 12 GUI, but I also have Fritz 17 GUI.

And my computer is a decent one and less than a year old, so no issues there.
