Re: Dylan Sharp Vs. Harvey Williamson (G4)

I do not know if the opening position is a draw. I believe it is a draw but I am not sure about it. It may be a win for white and I even have no proof that it is not a forced win for black. It is clear that what I meant by the word conclusion is not only to the claim that the position is a draw but ...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

The conclusion is wrong. You meant to say "the conclusion could be wrong", for the reasons you stated. But after I found 18. Rc2 Re6 it took me less than an hour to see black was winning, and I didn't need to solve it to a mate in X. My conclusion is only wrong if Harvey and me can't tell the diffe...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

Bf5 also wins after Rc2. White is holding on by a string in the current position. I think I can defend Rc2 Bf5. Of course it'll all be moot if Harvey beats me. But think about it, white MUST have a draw with best play, lest Harvey wouldn't care if I played Rc2 or Rcc1, because he'd know a line that...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

I am afraid that the game is going to get dark again if people suggest alternative wins. I did not give a lot of computer time for the relevant position but I did not see a forced win after 18.Rc2 not with Re6 and not with Bf5. Note that even evaluation of +3 by stockfish I do not cosider as a force...

Re: The day when imagination and will was stronger than artificial intelligence. Man against chess machine. November 201

You can see the engine having to move instantly or within a second to keep up with the clock. Without lag every engine move could have been played with 1 second more. Father wouldn't have been able to draw that game if it was in person (not over the internet) or with increment. And if he could, why...

Re: The day when imagination and will was stronger than artificial intelligence. Man against chess machine. November 201

I see bad engine moves. Would a little bit of more time really change them? Yes. Father wouldn't be able to win his games if there was increment, because he's abusing GUI bugs and lag to do what he does, if increment was set to compensate for GUI bugs and lag, he wouldn't be able to do it. And if h...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

You have no way to know if only zullil can see his PVs.
The only thing that you can know is that you cannot see his PVs.

You have no way to know that zullil does not share his PVs with other people assuming the relevant people do not share them with all the world.

Re: Limiting nodes to reduce engine strength

Not a fan of a depth limit, since they can occasionally be quite "coarse" in terms of time. I have a pretty decent NPS idea in the works. I have normalized on 2800 Elo == 6M nodes per second (on my MacBook). Elo scales down the NPS and introduces evaluation randomness. And it is actually working pr...

Re: italien opening

I think that even in the last case they can generalize from their experience against engines and play correctly moves that they know to be good in similiar situations. Engines and humans play so completely different chess that even if you get a variation where you perform relatively well against en...
