Leela Zero( A Neural Network engine similar to Alpha Zero)

You can try vs hard mode. Hard mode is just 100-150 elo better than normal(I think). She still play weak tactics in hard mode.

I cant wait 5 sec, i make move instantly..

Leela Hard level ID 119. (my thinking time, about 15-20 mins)

1. Leela did serious blunder at 3 ply tactics (not acceptable at 1000+ level) 

2. Another serious free hanging rook at 9 ply tactics (not acceptable at 2000+ level) 

Results so far, +2 =0 -4 ( in favour of Leela) 

I thought I am going to get draw in this game, but at move 30 Leela did serious blunder (3 ply missing blunder). 

At move 39 she did another blunder again (It is hard to see at lower ply but I immediately sensed that there was possibility of free hanging rook. (Leela should do defensive fortress, it would be still hard to play Q vs R in defensive fortress. 

Leela network will be upgraded from 6x64 into 10x128 larger network. Some tests claimed +50 elo immediately after upgrading into larger network. 

Great, that was long overdue. There was no progress in strengh the last 1.5M games (or 1/3 of the time since first release).

Unfortunately 50 ELO is few. So maybe the new NN is weaker than the old one if it has the same thinking time. I am eager to see how fast it can learn and which strength it can reach.

Edit: Oh, I see that it has gained 50 ELO in matches against other engines, right? So it gained 50 ELO despite the computational cost of the larger NN. Then 50 is a good value. Great.

Another 150 elo jump from new network in yesterday. Leela is close to Grandmaster Level.

If Leela doesnt stall like A0? She will pass both SF& A0. 😋😊

Is there a website through which I can play her, without having to download software? (except maybe a simple interface) A browser-based interface could relay chess moves between the public and a remote implementation Leela? (is that what you're already doing?)

Thanks, very impressive, she crushed me in Normal setting.  I had better stick to Easy for now!

She is still losing badly....actually playing worse French defense on version 125 than 122. Really bad bad on Nc3, Nd2, and e5.

I will admit she pulled off a nice positional sacrifice against me... finally!..worth 2 pts.

1800 beating Leela? Huh, Are you saying easy level?

Leela Zero vs Stockfish 9 in long time control 60 mins game. Leela attempted to kill Stockfish with one piece sacrifice for better position!! (same as Alpha Zero), unfortunately, she missed some tactics/blunders and eventually lose.

Leela is a piece down for positional sacrifice, SF agreed black is minimally better, Wow!

I like the way how Leela evaluate the position, in move 14. Leela saved her pawn on c6 by playing d5?! (rather than taking back stockfish's light bishop. Of course stockfish light bishop as worthless as a pawn because all white pawn are in white color). This is out of box thinking in chess or too much positional sacrifice!!

Are easy and normal mode been upgraded as well, because do seems shem makes same or even worse blunders specially easy. 

As non hard coded engine i do expect even with elo going up to still make blunders , just like human would.

I count tgis as a win, just didnt calculate anything really in normal mode.

Could you tell us a bit about the website that the screenshot is from?

What I really like about leela is how she puts pressure on your development as early as possible, it seems she just tries to really tries so hard to make it as hard as possible for you. Guess against a good player it's still a mistake sometimes as blunders can happen with such behaviour, but against beginner like me it seems my plans can never be carried for long as she really does (easy mode) what can embarrass me the most and the fastest. Probably is she sacrificing her own development through for that and I'm sure if I new openings better, I would immediately take benefit of this (? at least in easy mode ?) anyway it gives Leela a real personality, nothing like StockFish, to play against. Real tigress attacking you as hard as she can and as hard as she can always.

Macer what are your questions about lichess website? Just go there and just check by yourself if you want to know what this website looks like, it's not our business here talking about Leela! This website is not linked to Leela if that's your question.

 Now the very interesting thing about Leela is she always play the same. Any human player tries to find the weakness in her move order then, I wanted to use London System against Leela, she did every misery to me I can expect (very interesting helps you improve alot!) but after some times I found some situation she's not at ease that much, indeed because she did too much aggression, sacrificing long term development. After these 26 minutes from my previous message, I found a way to find a draw with her.

My best accomplishment by now as previously I abandoned as I was done a piece every time at some moment.

If you want to improve one of your opening against Leela, working on the weaknesses, that's really a very good way. Much more interesting than playing against SF.

But the very one scoop I had to give here is that Maybe if A0 worked the same, even if SF had hard time against (without his books) then any human player would have him beaten easily, just have to work on the same suit of moves until the weakness is found (as it's obvious that the same way I found a draw, I could if I want to spend a few hours, find a win).
