Re: Whatever is current - Amazing Leela

Winning a pawn increase significantly my chances to win against other human opponents. What if the best line for black includes sacrificing a pawn, and both exchanges (you keep the Bishop pair, so it's knights for rooks), so you end with huge material deficit in a position you have no idea how to c...

Re: Whatever is current - Amazing Leela

a human does not need to find the moves assuming all is home preperation so I believe 2700+ players are going to have motivation to learn the correct lines in order to win. All this has been going on for more than a decade, for example, back when Freestyle chess was popular, those players were cork...

Re: Whatever is current - Amazing Leela

I think that falls outside of the scope of this thread (where I've been claiming you should focus on the relevant chess lines instead of generic chess lines, so if it's "not played as often in engine tournaments" that means the line is generic), but, sure, I'll see what I can do about those lines a...

Re: Stockfish patches

They give elo estimate for every change and if you add all the estimates that they publish the elo improvement shouls be clearly higher. You have a basic misunderstanding of statistics. The elo estimate calculated by fishtest is (median) unbiased over all patches (both failing and passing). In othe...

Re: Stockfish patches

Simplifications can pass with slightly negative score but the cases when it happen are rare. The main problem that I see is that the stockfish team give wrong information about elo. They give elo estimate for every change and if you add all the estimates that they publish the elo improvement shouls ...

Re: buying a new computer

Some note: Only the NN engines (like Leela) has its "own openings". AB engines have only tendency to play lines from start position. If you want to create a good book for an AB engine you need huge number of games between that engine and many other engines to know the weakness of that AB engine. Th...

Re: ScorpioNN v2.9.0-n_maddex_INT8 is great:)

INT8 is much better than FP16. Some days ago at TCEC: Scorpio INT8 vs LCZero1pct v0.21.2-n42547 +0 =4 -0 Scorpio INT8 vs LCZero1pct +0 =4 -0 Now Scorpio INT8 vs LCZeroCPU v0.21.2-nLD2 +1 =1 -0 Will LC0 ever use INT8 instead of FP16? You are aware that LCZero1pct v0.21.2-n42547 was only using 1 pct ...

Re: Why there is no interest in Computer with odds Vs Humans match?

Each year the maximum alloted odds for engines increase as both hardware like cpu & engines get better. Now i'm curious to know what is possible the present sweet spot ? -> two pawns + move or knight for pawn with or without moving first ? P.S. -> Namakura said few years ago than he will beat any e...

Re: Whatever is current - Amazing Leela

We do not need the pgn if only the results count. It would be enough to write down the result 1:0, 0:1 or 1/2 if elo is the target. The game score information is unimportant if the target is winning. If the target is the result, we also would not need to watch a soccer game, a tennis match or a car...

Re: Stockfish patches

SF dev. Why are some (up to 6) patches released in one day (often less than 1 hour), and then again 10 or more days without a single patch? Why so many within 1 or 2 hour? It just depends on when the maintainer, which is Marco, has the time to make the decision whether a patch passes or not and upd...
