Re: Dylan Sharp Vs. Harvey Williamson (G4)

Everyone is obsessed with Elo, yet hardly anyone understands how important engine learning is in this regard. :shock: I suspect this is THE reason Learning died. The problem with it is that an engine with Learning will have a lower Elo on games. What seems to happen is that the engine faces a posit...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

The reason I want to do it without tablebases is that for analysis we do not have tablebases for every position and I want to know about the ability of chess engines to analyze chess positions and get correct conclusions and I can learn about the ability to do it for positions with more than 7 piece...

Re: Can current top engines still be beaten?

The question is: will there ever be an engine that wins 1 game vs that setup? Oh yes, Stockfish is nowhere near perfection, I could say that a top correspondence chess player using 6 days per move could find a string of moves that'd beat your conditions, so if some engine of the future is able to f...

Re: Can current top engines still be beaten?

I doubt if chess engines can be beaten today at correspondence chess. Correspondence chess is already dying based on percentage of draws and I often see tournament with more than 90% draws and I suspect that there are wins only because of clerical errors or games when both players play for a win and...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

I have used a gui that does the does basically the same thing. Hopefully you're not talking about Aquarium's IDEA, which is an abomination and you're basically wasting 90% of resources when you use it. The effects of learning can't really be emulated by a GUI, which would rely on Exclude Moves in l...

Re: 237 Mn/s for Stockfish on an 2xEPYC 7742

Yes, SF hasn't become any stronger at 1s+0.01. This is particularly related to this patch : https://github.com/official-stockfish/Stockfish/pull/2260 It lost 40-50 elo at 2s+0.02 ; lost ~4 elo at 10s+0.1 @ 1.6mnps ; gained ~1 elo at 20s+0.2 ; gained ~5 elo at 60s+0.6 and around ~12 elo at 180s+1.8....

Re: 237 Mn/s for Stockfish on an 2xEPYC 7742

How far it is above Crafty really doesn't affect my comments. 2K nodes per second is not going to beat a GM. Might not beat a master, since most of the speculative pruning stuff really needs exceptional search depth to bypass the holes it causes. 1 second per move vs 180 seconds per move? Maybe. Bu...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

You confused the order of moves in the pgn during the game without changing the position. Here is the full game for people to analyze [Event "PGN Import"] [Site "?"] [Date "?"] [Round "?"] [White "Dylan Sharp"] [Black "Harvey Williamson"] [Result "*"] [BlackElo "2400"] [ECO "A00"] [Opening "Grob (Fr...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

Note that for me more interesting then centipawn is analysis like white depth 20 lose against black depth 10 white depth 21 draw against black depth 10 white depth 21 lose against black depth 11 ... The idea is that if white want a draw simply play comp-comp game at small depth to see if white can d...
