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...

yes, sure, you are right that hardware-developement plays a major role in computerchess and the speed of progress as well ! 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...

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...

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...

hi Uri,
bad study as it seems after 15 sec SF-dev search:
SF says Kh7 is a dual !?

I agree bad study.

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 would like to know what top 2775+ player has the record without losing any classical games, and what top 2775+ player won the most consecutive straight classical games. I can NOT find the answer anywhere, and I have search with different search engines. It would be interesting to see these two pl...

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...
