Re: mmt Vs. Ovyron (G4 D5 BG2)

ICCF rules 7.2: 7.2:"If during a non-server game, it is found that an illegal move has been completed, the position immediately before the irregularity shall be reinstated. The game shall then continue from this reinstated position and guilty player shall be penalized ." In what way is the guilty p...

Re: mmt Vs. Ovyron (G4 D5 BG2)

if 6... Ng6 or other then need to analyze. I don't know ICCF regulations, but if 6... Ng6, I say White claims victory for illegal move. It is not based on the ICCF rules ICCF rules 7.2: 7.2:"If during a non-server game, it is found that an illegal move has been completed, the position immediately b...

Re: 1.g4 opening is losing?

When I played 30 games between SF10 and SFdev 16 games were 0-1 (here 10 first). Other games were draws. Does this indicate, that 1.g4 is losing move? Easy question. Since chess hasn't been solved, no first move is losing. This really is common sense, and no engine games are really needed to stumbl...

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: Can current top engines still be beaten?

Note that stockfish with many cores is not determinsitic so you have no way to find a single winning line that you can use to win against it. You don't need it, all you need to do is leading Stockfish to a position that it misevaluates, then it doesn't matter exactly what moves it plays, because it...

Re: Can current top engines still be beaten?

I'm tempted to believe that unaided top engines, running on some baseline hardware with reasonably limited time controls, can still be defeated at corr chess. A strong, skilled human can guide the play [while analyzing] and gain a huge depth advantage in critical lines. Not to mention the additiona...

Re: Stockfish 11 at 120k nodes per move

What is the meaning of "fixed nodes per move", though? Because when you force the engine to play like that, you're forcing it to abort the search on some random point of the current iteration, and then I'm not sure what's the best strategy to follow when choosing a move. Suppose it's on the middle ...

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...
