Fritz GUI (technically Komodo 12 ChessBase GUI), and yes, new engine. It was obviously not playing like normal Lc0 versions. Evaluations of positions with material lost were drastically different.
WOW. Then these results are very very impressive.

Re: Lc0 51010

I noticed that Lc0 started a new network from scratch, and after just ten iterations it showed a rating around 1500 (now 1466). I have read that these self-play ratings are inflated, so I imagined that its true strength was lower than 1500. So I played it a couple games at 5' + 5" (I'm too old for ...

Re: End of Era is there: SF is finally beaten!

And why the AB that contains handcrafted positional data is not a database? :roll: By your definition it IS also, so no problem.... You call software coding a database ? Well done :D You said "or some positional data" and coding e.g Rook on open file worth +0.02 more is positional data. Eval functi...

Re: End of Era is there: SF is finally beaten!

While leela is a very interesting project, you just cannot compare it to AB engines, that use manual tuning for all positions. Whether the network contains images or samples or patterns or some positional data, it is still a database (and a considerable one too) And why the AB that contains handcra...

Re: End of Era is there: SF is finally beaten!

There is no any "spectacular" and there is no any "plan" on the side of Leela. In reality the position after 20.-c4 and the good continuation is in the 32930net of Leela. To prove this I used the weak GTX 1060 to find the 21.Bg6 move. From net30100 to net32000 Leela want to move 21.Be4, 21.Bxc4, 21...

Re: End of Era is there: SF is finally beaten!

A 1000 core Clusterfish may not be suffering from the same horizon effect Stock and Bluefish are. After all, it would get 800-1000 million NPS. A 1000 core Stockfish would be like regular stockfish getting 1450 minutes + 3 minutes per move vs Leela getting only 120 minutes + 15sec per move. It coul...

Re: End of Era is there: SF is finally beaten!

There is no doubt that we are in a new Era ... you have to be living under a rock if you don't see that. Lc0 basically outplays SF almost every game. Sure it doesn't win many games it has a big advantage in and will lose to one move tactical blunders because it still has some tactical weaknesses, b...

Re: Knight equals 48 pawns?

I downloaded the latest Lc0 about a week ago on my laptop (with GPU 1060), and looked at its analysis (infinite mode) on lots of positions. Typically, in the opening evals are roughly double what they should be; in general a clean pawn up shows as about two pawns. However, the initial position with...
