Incredible! It's amazing to see what these Neural Network engines are coming up with.

It is better than SF 10. This is latest SF devepment version from yesterday(see the version number).

This version of SF is +8 elo above SF 10. And no testers use SF 10 anymore, too old.( As far as I can recall, SF 10 was released in 29.11.2018 I think).

 

And do you know that the game ended as SF loss. The position is already lost for black.

Leela realizes the potential of the fawn pawn :)

When an engine evaluates a position it is comparing alternatives against its own valuations. Can you compare engine evaluations of such different engines? what I mean is as long a the valuation works for that engine it doesn't matter how it compares to another engine. isn't evaluating positions as the number of pawns just a relic of early engines which becomes less meaningful in complex positional play?

Lc0's evaluation is still not on par with the top engines yet. It only scored 3/12 against SF, 5.5 against Houdini and 5/12 against Komodo.  The above game ended in a draw. SF had right evaluation it seems.

 ps. Lc0 finished with a minus 34/72 vs sf 51/72

@pawn_checkmate it was a draw? In the final position even SF says white is completely winning

 Am not sure about the above game.. SF hasn't lost a single game since the championship started. So it's safe to say it was either a draw or lose for lc0... 

edit.. SF suffered first loss against Houdini just now in the semis

Now the truth comes out. If it was just a bonus game, they could have been experimenting with something. Don't you hate fake news?

How are scores equal? Stockfish is at 19.5 and Lc0 is at 17. Stop with your fake news updates.

 

 

Get out of your narrow knowledge, There are more than one chess engine testing site!

And the network in TCEC is already 2 weeks old. Leela network is bonus site is approx +30 elo stronger  and SF is also approx +3 elo stronger than TCEC.

What is my agenda?

Did I tell you Leela is stronger than SF?

(Read it twice, I already said, SF as no 1 and Leela as no 2)

 

I just post the pgn and give source of location!

 

There is no incorrect information!

You just need to see your doctor or take your own pill.

Doctors and their pills.  Got a problem?  We have a name for it and a pill.  Sure the ingredients are taken from a common plant, but the chemists have isolated the active ingredients, patented the process, marked up the cost and pressured, bribed and bonused the doctors who prescribe it.  As a doctor, you are a pawn of big pharma.  Doctors and pharma are one big team focused on money, who actually need sick people to survive.  Give them a pill, don't tell them about diet.  Sorry, a pill is far from any solution for your patients.  Pills are band-aids and doctors (in the us) are traitors and ignorant.  They have sold themselves and their patients for a little money.  The medical associations is a big cruel joke.  See a doctor, take a pill, well said mrbossdoctor...

Although we both love chess, your posts are harsh and you are quick to attack others, I have noticed.  You are probably a very good doctor (meaning you push many pills).  With all that expressed, I do know you and I share similar interests in chess, but we are very different.  As a doctor you are in the thick of the matrix and you feel successful based upon income.  However, the army the pawn fights for is much more important than meeting the status quo of being "employed".  If you are a good pawn, and work to help your team, you may want to ask what the bottom line of the team you work for is.  If it is money, don't be surprised if policies imposed by your team injure rather than help others.

Doctors who don't prescribe pills, -that is the good kind.  Please take the pill yourself before prescribing it.

As a doctor, your most likely agenda is...money.

Whether or not your conspiracy theories say it's good, modern medicine saves lives. Just look up world population charts dating back a few 100 years.

In the 1800s about 40% of people died before age 5 and over 50% died before reaching adulthood.

Now only ~3% die before age 5.

I wonder when all top players will feel the need to have nn engines.

Maybe you've mentioned it before, but I've forgotten, what kind of hardware is Leela using for those games?
