Re: Lc0 51010

What AZ and LZ showed is that there are serious weaknesses in existing A/B programs, which they can exploit. As for what it means for humans playing chess, the A/B engines already showed that mobility and king safety can compensate for material to a greater degree than was generally believed, and t...

Re: SIM new version

... Several are open source, easy to compare... Even if the engine sources are different, they use more and more the same known to work techniques. I expect them to be more and more equal in the best lines that they find. So they are not clones or derivatives per se, but are partial derivatives in ...

Re: Depth reduced but ELO increased

Yes, it happens often that a change increases branching factor instead of reducing it, but the tendence is, if the engine is improving, to reduce it.

Re: Draws with Knight odds are possible against a top GM?

I do not believe that lc0 is mimicking human play much better than a regular AB CPU engine in the first place. I read that lc0 does not care between different wins and does not care about the fastest win and it is not typical for humans. Anyway is a very interesting experiment, as should be more hu...

Re: QN vs RBB material distribution

Not exactly the same endgame but in the first game of the current Ccc event happened this: 6k1/2Q2p2/4b1p1/4p1P1/3b2p1/6K1/8/8 b - - 19 120 [Event "CCC 6: The Winter Classic Playoffs (10|10)"] [Site "?"] [Date "2019.02.24"] [Round "1"] [White "Stockfish"] [Black "Andscacs"] [Result "1/2-1/2"] [ECO "...

I see no reason for the assumption that dynamic stuff is better than combination of static stuff and dynamic stuff that stockfish has.
Personal experience tuning everything on hand.

Re: Top Engines without Piece-Square Tables?

Are there any engines above, say, 2700 that have eschewed the use of piece-square tables? Edit: Excluding neural nets. If Stockfish removed them, they will probably need to add some positional parameters and retune everything to compensate. I suppose that it will become a little stronger, as dynami...
