Re: Chess.com 2018 computer chess championship

Lc0 now has a training run using tablebase rescoring for training, rather soon we should be able to see improvements in endgame play from this. And you still keep "0" in the name, what a joke... Yes. They do that, to annoy you. And it's good. :D But that's a side experiment, right?? The main nets b...

Re: Leela (lack of) endgame technique?

OTOH: if u state that after around 3-4 months of training a NN gets a playing-strengh that is lets say 200 elo weaker than the top of the crop (a-b-engines (PC) after more tha...

Re: Leela (lack of) endgame technique?

LC0 (formerly LCZero), a new approach in computerchess to play the best chess by using a "Neural Network" instead of prunning moves away by "alpha-beta-prunning" (as current engines are based on still momentarely as SF/Houdini/Komodo are), is more or less 1 year among us and performs increadable ca...

Re: Amazing fortress : Sarana vs Khismatullin 51.Rc1!

In this position: [d]8/2r3k1/8/1p1p1p2/p2PbPp1/PB4P1/1P1K4/4R3 w - -; seems to be that both the moves 51.Rc1 and 51.Bd1 lead to draw. For this reason it is better to change a bit the psosition (e.g.): [d]8/2r3k1/8/1p1p1p2/p2PbPp1/PB4P1/1P1K4/5R2 w - -; and now only move 51.Rc1! (Sting SF 10) solves...

Re: CCCC Rapid Rumble results simulator

It is easy to predict even with a short tournament , because each engine is ranked with a good margin over the other, except Komodo / Houdini. So Stockfish is number 1 with a good margin, Lc0 number 4 with a good margin, then Fire, then Shredder, so the probability to have the number in the good or...

I can NOT find the answer anywhere, and I have search with different search engines. It would be interesting to see these two pl...

Re: CCCC Rapid Rumble results simulator

lc0 memorizes patterns and was trained first with random move so probably each starting position even if of course she plays more and more the same openings with more training. But she can plays every positions thanks to that ( patterns and all opening trained ). I call CCCC fair condition for Leel...
