Re: my Lc0 spreadsheet

Are we sure Lc0 & A0 use the same definition of "node"? No, but it's quite possible. Also, I was thinking of the upcoming TCEC superfinal, where the effective Leela Ratio (as defined in the paper) is close to 1.0. According to my results, Lc0 t40 should win. According to the results of Hugo, it is ...

Re: my Lc0 spreadsheet

Then again, what constitutes as fair or unfair anyway? Yes, it's not about fairness but about comparison with A0, so the name itself is wrong because it has nothing to do with Leela. And the number 1 does give the wrong idea that it is "fair", when really it just means "equally unfair as A0's hardw...

Re: my Lc0 spreadsheet

Leela Ratio is in deed hard to estimate. I would say mine is average 1.1. From the startpossition Stockfish with 12 cpus has about 18.000 kNs in 1-2 Minutes and Lc0 24.000nps - 25.000 nps. So this is 1.2 ratio. But when I observe the games, SF is far over 20.000 kNps after very few moves, while Lc0...

Re: Dual RTX 2060 for Leela

What is a node in lc0? This is not a stupid question, btw. Could be every node in the tree. Could be every node in the tree plus every node outside the tree. If it’s a tree node, does it count 1 for every time the search goes through, or just the once when it is visited the first time? Could be the...

Re: Playing the endgame like a boss !!

I have posted this previously on a different thread and MikeB's 12-core took also minutes to find the correct moves... Thanks, MikeGL & MikeB. I take it the evals in the game score are those of the engine that just made the move. (This isn't so important, but I found that after 69... Kxh6, SF's eva...

Re: Playing the endgame like a boss !!

Sorry but I disagree, I have seen endgames of Lc0 where winning moves can't be reproduced by AB engines because it involves zugzwang at the end of the PV which would win. Ok, but to be fair I have seen very strong tactical combinations of SF too with many mating nets at the end against Lc0, which L...

Re: Playing the endgame like a boss !!

If Kingcrusher thinks "science fiction move" is a compliment, he should think again about what "fiction" means. What he means is some chess moves that are so amazingly incredible that they seem taken out from a science fiction novel. Something that is real but seems unreal because of how unbelievab...

White is dead lost, no?
Draws because of fortress with Kf1 or stalemate with Ke2 and R on first rank.
