Re: AMD Ryzen R9 3950X new build

I would like to keep my question in the same thread. I have decided to buy a new computer to upgrade my chess analysis using LC0. If I buy 2 video cards (say RTX 2080) what processor would be reasonable to also run stockfish at the same time on a given position? My idea is to run analysis on a move...

Re: stockfish 10 vs. Mephisto III S Glasgow

What Stockfish does within 1000 nodes is completely irrelevant because no sane people would use it like that. Basically, if Stockfish at 1000 nodes could defeat Mephisto, then it'd be used at 100 nodes and the question would be why it can't defeat Mephisto, with the same arguments. If the Mephisto ...

Re: AlphaZero No Castling Chess

It seems that AlphaZero has been trained to play "no-castling chess", see the interesting article Kramnik And AlphaZero: How To Rethink Chess‎ at https://www.chess.com/article/view/no-castling-chess-kramnik-alphazero Good to know the tastes of super-GMs like Kramnik for what they consider as accept...

Re: AlphaZero No Castling Chess

Hold on, back when the queen was made powerful in chess, wasn't that a radical change that made the game completely different? Yet it was adopted, so why do people want to keep the nature of chess unchanged? Why are people hesitant to add rules that destroy the nature of chess, if that was done in ...

Re: stockfish 10 vs. Mephisto III S Glasgow

Also, misdefining intelligence as adherence to some restriction pulled out from a hat is, well, not very intelligent. I could probably write na engine playing something resembling 1800 Elo chess in 1000 nodes searches, but its code would be ugly beyond measure. Thousands lines of code detecting tac...

Re: stockfish 10 vs. Mephisto III S Glasgow

To play a move or a game, a chess engine will get some hardware time. The strength and "smartness" of an engine follow from the quality of the moves played. Whether to select these move it uses 1 nodes, 1K nodes, 1M nodes, 1B nodes... is irrelevant, the important part is how good of a result it can...

Re: stockfish 10 vs. Mephisto III S Glasgow

"As long as the programs do not plan to win but make moves , that win material or mate, they do not understand chess."
What does this even mean?

So if an engine goes for the mate, it doesn't understand chess because it didn't plan to win? :roll:
I hope Mclane realizes that a mate is a win.

Re: Dylan Sharp Vs. Harvey Williamson (G4)

0.00 is only for positions that you are sure that they are drawn or you think both sides have equal probability to win. I'm sure those positions are drawn even though I can't prove it. Also, Harvey's moves up to this point have been pretty much forced, because other alternatives were 0.00. Even if ...

Re: AlphaZero No Castling Chess

Hard to see how this would increase the amount of decisive matches. No castling cuts down the search tree quite hard so it should be much easier for an engine to see the forced win or forced draw. Maybe for human chess it can make the game a lot more decisive because positions become sharper, but it...
