Re: Stockfish wins CCC 3: Stage 1 only after last 60th game

The games I was complaining about mostly had both sides with evals in the same general value/direction. I agree though they differ between engines. Stockfish too I have noticed seems to give some big evals in opening positions but if you push the game another ply forward the evals change quickly. Th...

Re: Stockfish wins CCC 3: Stage 1 only after last 60th game

I find even during the match, the only way to see/download games is to look at the crosstable and select them from there. Seems not optimal. Another comment (and I do appreciate the tourney): the openings are sometimes quite unbalanced. I understand that seeing a whole series of draws is something m...

Re: Schizophrenic rating model for Leela

My impression is that when Leela wins, it is usually very interesting: it found something that alpha-beta searchers miss. When it loses, it is usually not interesting: it just goes down to a tactic, like a weaker alpha-beta engine.

Re: On-line engine blitz tourney January

From a theoretical opening point of view, white's response 9.BxB seems bad. It allows black to a obtain a pawn steamroller formation in the center, and a black gets a rabid attack on the f-file. White has a already conceded the f-file defender with 8.Re1. Stockfish evaluates White as better out of ...

Re: On-line engine blitz tourney January

AndScacs finds an opening innovation that whips up an attack on the king side. The line starts with 8.Re1? This unusual move is from the Cerebellum book. The normal move is 8.b4. Blacks response 8...Be6! is not found in the databases that I have. Maybe someone can find it somewhere. After this, Sch...

Re: Playing transposition table moves in the Quiescence search

I have looked at my code again after seeing this thread. I try to use the hash move in the q-search if possible, to possibly avoid calling the move generator. I found though that it wasn't quite filtering hash moves that originally were not from the q-search so that they met all the q-search conditi...

Re: AMD Ryzen 3000 Series CPUs

Interesting accent - Scottish (YouTube guy)?

I don't know if I believe most of what I hear, but it does appear that Intel will not have 10nm in production before 2020. If AMD can start shipping 7nm, it will kick Intel where it hurts, even more than the 2000 series is doing.

Re: Hard-Talkchess-2019 set

I think this shows, chess is an extremely deep and complex game. Not as big a search space as some, but still very deep.
